Lockhart Tactical UBS-12 Mount Only

LT UBS12

The UBS-12 (Under Barrel Shotgun 12 Gauge) is a door breaching shotgun system manufactured by Lockhart Tactical.

Typically Soldiers or Law Enforcement officers are forced to carry a breaching shotgun in addition to their standard issue rifle during operations. Our UBS removes this requirement. Our system consists of a Grizzly shotgun embedded in our proprietary quick release mount which is to be used in an underbarrel configuration much like the M203 grenade launcher.

Our shotgun cannot be operated independently due to not having a pistol grip behind the trigger. When firing the UBS, the magazine of the parent firearm must be used as a pistol grip. We will soon be releasing a proprietary Pistol grip and Buttstock which will be able to be quickly attached and detached on the UBS for independant firing without being attached to another firearm.

What can the UBS-12 Mount do for me?
Whether or not you're a Solider, LE Officer or Professional using this device for breaching, our UBS has a lot to offer. Civilian Hunters can benefit immensely by carrying our tiny UBS under their favorite bolt action hunting rifle. Nothing is better than peace of mind and security of having 12GA Slugs or Buckshot at your finger tips when it's needed most.

Apart for security reasons, Hunters could also quickly attach our UBS to help ensure they don't go home from a hunt empty handed. Maybe you won't see a deer cross your path, but if an unlucky flock of turkeys happens to surprise you... Seize the day! Our shotgun features a 2+1 magazine which means its perfectly legal for hunting.

Use our Mount to attach your currently supported shotgun, and connect it to another firearm platform!

Attachment Mechanism
The Lockhart Tactical UBS-12 features dual locking levers manufactured 100% in the USA by American Defense. These patended quick release, automatic locking levers are the best in the world. Rest assured, these won't ever be coming off unintentionally!

Mount Features:
Our proprietary billet aluminum mounts are machined entirely in BC, Canada and requires a mere 10 picatinny rail slots (4" / 10cm") to attach securely. Our mounts will soon feature a proprietary quick attach Buttstock and Pistol grip combiniation to convert our UBS to a Non Restricted shoulder fired Micro Shotgun. Shortly we'll also release our Quick Attach Optic mount which will sit ontop of the UBS while in the shoulder fired configuration and shall hold zero on optics when detached and reattached.


Lockhart Tactical UBS-12 Quick Attach Buttstock / Pistol Grip

The UBS-12 Quick Attach Buttstock was built to allow the user to attach our buttstock in seconds, turning the under barrel into a stand alone combat / home defence shotgun.

Every aspect of the buttstock is quick release. Simply slide the top button back to lock or unlock the stock onto the UBS-12 mount.

The buttstock features 4 (four) internal spare shell tubes. The top three tubes hold 3 shells each, while the bottom shorter tube holds 2 for a combined total of 11. The tubes could also be kept empty or filled with small survival items such as matches, small first aid items, fishing line, hooks, paracord, small knives and more!

To open the stock to get access to the internal storage tubes, simply slide the recoil pad gate lock forward, and rotate the recoil pad to the side.

The sides of the UBS-12 are tapped for the attachment of 2.5" picatinny side rails (sold seperately) These rails could hold a compact laser, or quick attach 5 shell sidesaddles.

There is nothing like this on the market!

Specifications:

  • 100% billet aluminum
  • 100% made in Canada
  • 100% tool-less to attach and detach
  • Holds 11 spare shells internally
  • Can hold small survival tools internally
  • Rails can be mounted to the sides for additional attachments
  • Add 5 shell quick attach sidesaddles on the left, right or both sides

Lockhart Tactical UBS-12 Quick Attach Optics Rail

The UBS-12 Optics Rail was built to allow the user to attach any optic / red dot to the UBS-12.

Once you initially sight in your shotgun on our rail, you will be able to remove and replace the optic package on the UBS-12 without having to ever rezero the firearm.

To attach and remove the optics rail, simple unlock the UBS-12 locking quick release lever and remove / replace the rail.

Specifications:

  • 100% billet aluminum
  • 100% made in Canada
  • Holds optical zero when removing and replacing optics on the UBS-12

Lockhart Tactical UBS-12 Quick Attach 5 Shell Holder

The UBS-12 Five (5) 12ga Shell holder allows the user to quick attach a sidesaddle to the left, right or both sides of the UBS-12 buttstock.

Use the quick release lever to lock the sidesaddle into place in seconds when you need it most.

Bullet Selection
There is no "universal" bullet - that is, no single bullet for all shooting applications and all shooting conditions. The information below has been prepared to help you choose the right Sierra Bullet for you in any application, whether hunting or target shooting. Bullet selection is, of course, a personal preference, but there are some important technical considerations that must be addressed. We hope that the rifle bullet descriptions in this section will help you make the correct bullet selections for your applications as well as your shooting conditions. As always if you have any questions about the information below please contact us here or by calling 1-250-715-7290

The rifle bullets in Sierra's product line are arranged in six classifications, depending on the intended application, design features, and the range of cartridges that may use the bullet. One classification includes all of Sierra's match target bullets for target shooting, and five classifications are for hunting applications.

These six classifications are:

MatchKing Bullets: This is the classification for Sierra's pre-eminent target bullets. The driving motivation for the design of each MatchKing bullet is accuracy. These bullets have very thin jackets drawn to an exacting concentricity standard of 0.0003 in maximum variation, and their weight is held to within ± 0.3 grain. All MatchKing have a hollow point design with a very small meplat for high ballistic coefficient. The majority of these bullets have a boat tail shape to further minimize drag and improve ballistic coefficient. They are manufactured to the very highest quality standards.  Their accuracy has been acclaimed worldwide, and they have been used to win more target competitions than all target bullets from other manufacturers combined. While they are recognized around the world for record-setting accuracy, MatchKing® and Tipped MatchKing® bullets are not recommended for most hunting applications.


Hornet Bullets: These are 22 caliber bullets of 40 and 45 grains in weight designed in the traditional shape for the 22 Hornet cartridge. Their purpose is hunting varmints and small game, and they are designed to expand reliably at velocities in the 2500 to 2800 fps range, although they can be loaded in cartridges generating up to 3500 fps muzzle velocity.

BlitzKing Bullets: These bullets are designed for explosive expansion in varmints and small game and with accuracy characteristic of the MatchKing bullets. The tips of these bullets are made of a proprietary compound, and the jackets are thin for enhanced accuracy and explosive expansion. The lighter bullets in 20 & 22 calibers are designed to be fired at muzzle velocities up to 4400 fps. The lightest 6mm BlitzKing bullet can be fired at muzzle velocities up to 4000 fps.

Varminter Bullets: This classification of bullets is designed specifically for rapid expansion and instant kills on larger varmints and small game. The shapes of bullets in this classification include hollow point (HP), spitzer pointed flat base (SPT), and semi-pointed (SMP). Bullets in this classification have thin jackets to enhance expansion but with sufficient strength to be fired at the highest muzzle velocities in the cartridges for which they are intended.  Bullets labeled as Blitz are designed for medium velocity (under 3600 fps).

Pro-Hunter Bullets: All bullet shapes in this classification are flat base, and they include round nose (RN), semi-pointed (SMP), spitzer-pointed (SPT), flat nose (FN), and with a hollow point (HP/FN). A few bullets in this category have Sierra's proprietary Power Jacket to enhance bullet expansion in game animals when fired from medium-velocity cartridges. All these bullets have medium to heavy weights in each caliber, and they are designed for a combination of penetration and expansion in medium and heavy game animals for their calibers.

GameKing Bullets: All bullets in this classification are for hunting and all have boat tails. Their shapes include hollow point boat tail (HPBT), spitzer boat tail (SBT), and full metal jacket boat tail (FMJBT). The bullets in this classification have medium to heavy weights in each caliber. With their boat tail shapes, they have high ballistic coefficients, retain their velocities well, and resist crosswinds and vertical winds well as they fly. These bullets are designed for a combination of penetration and expansion in medium and heavy game animals for their calibers. 

BULLET DESIGNS

Sierra also uses several basic shape designs for rifle bullets, although some features of different shapes may be incorporated into a single bullet. Shape and characteristic features easily distinguish each design.  The most popular are described below.

Sierra Bullets Hollow PointHollow Point is a bullet shape used for the MatchKing bullets as well as a number of Varminter, GameKing and Pro-Hunter bullets for hunting. The Hollow Point shape has an opening in the nose, which depending on the use of the bullet, may be designed for complete fragmentation, controlled expansion, or no expansion at all (MatchKing). With the wide range of Hollow Point bullet performance capabilities, proper bullet selection for a particular use is crucial to ensure the desired performance in the field.

Sierra Bullets SpitzerSpitzer is a term taken from a German word that means sharp pointed. The spitzer shape is readily identified by a characteristic long ogive point shape closing with either a small diameter exposed lead tip or with the proprietary compound tips in Sierra's BlitzKing bullets. Spitzer bullets may have either a flat base or a boat tail and have much higher ballistic coefficients compared to the traditional round nose or flat nose bullet shapes. The spitzer shape with either a flat base or a boat tail has become the "standard" for hunting bullets today.

Sierra Bullets BoattailBoat Tail bullets have a smaller diameter base, a shape resembling the configuration of the stern of a sailboat. This shape significantly reduces the base drag on a bullet, giving boat tail bullets a significantly higher ballistic coefficient than flat base bullets of the same weight and point shape. Thus, boat tail bullets have lower sensitivity to crosswinds, higher retained velocity downrange, flatter trajectories, and higher energy and momentum delivered to the target than their flat base counterparts.

Sierra Bullets Semi-Point Semi-Point is a bullet shape designed to provide heavy bullet weight within a given bullet length, and at the same time provide a ballistic coefficient higher than either the flat nose or round nose bullet shapes. The semi-point shape features a nose with a tip of exposed lead that is larger in diameter and more rounded than the spitzer shape. This shape sometimes works well in rifles having twist rates too slow to stabilize the longer spitzer or hollow point bullets of the same weight.

Sierra Bullets Full Metal JacketFull Metal Jacket (FMJ) bullets are easily recognized by the jacket, which covers the entire bullet forward of the base with only a small amount of exposed lead at the base. Sierra's FMJ bullets also have the boat tail configuration. When used at reduced velocities, Sierra's FMJ bullets are nonexpanding in light game, and often are an ideal choice for varmint or predator hunters wishing to minimize pelt damage. FMJ bullets also allow hand loaders to effectively duplicate 5.56 mm and 7.62 mm ball ammunition for use in military style rifles.

Sierra Bullets RoundnoseRoundnose bullets are a traditional design often used by hunters in areas affording shots at game only at short ranges. This bullet shape is easily recognized by a large, rounded, exposed lead tip. The large amount of exposed lead at the nose causes positive expansion of these bullets at moderate velocity levels.

Sierra Bullets FlatnoseFlatnose bullets are designed especially for rifles with tubular magazines. The large diameter meplat greatly reduces the chance of recoil-induced ignition of cartridges in the magazine when the rifle is fired. A large amount of exposed lead at the nose of these bullets causes positive expansion in game at moderate velocity levels, especially those with a Sierra Power Jacket. The Power Jacket has a series of "skives" cut into the mouth of the jacket. The skives ensure positive and controlled expansion of the bullet at moderate velocities and are used in several Sierra handgun bullets as well as flat nose rifle bullets.

Pictured and described below are different design configurations of Sierra handgun bullets.

Sierra Bullets Jacketed Soft PointJacketed Soft Point (JSP) is a classic bullet design for deep penetration with high weight retention on medium and large game. Features include a special lead alloy core formulated to provide proper expansion qualities. On impact, the bullet will allow the core to flow over the leading edge of the jacket, in effect locking the core in place and retaining as much mass as possible. The jacket consists of specially dimensioned walls formed by Sierra's unique progressive draw process, which results in uniformly tapered, concentric walls with a heavy base. The JSP design is used in Sports Master bullets.

Sierra Bullets Jacketed Hollow CavityJacketed Hollow Cavity (JHC) is a design unique to Sierra and acclaimed for superior performance. Positive but controlled expansion is ensured by the unique cavity, which is formed in the core prior to final nose forming. The result is a small opening in the bullet tip over a large cavity for a good ballistic coefficient and balance. Sierra's Power Jacket provides positive, uniform and controlled expansion by means of specially placed skives in the jacket around the tip of the bullet. The JHC bullet design is used generally for handgun bullets in several calibers.

Sierra Bullets Full Profile JacketFull Profile Jacket (FPJ) is a design concept featuring a thick, tough jacket that covers the entire profile of the bullet. Intended for maximum momentum transfer to steel targets, this design generates good dwell time on the target for maximum "push." The heavy base is fully enclosed to withstand the high pressures of magnum loads and maintain "match" accuracy. The unique upset qualities of this design and strict dimensional tolerances combine to provide unsurpassed accuracy and performance. The FPJ design is a silhouette bullet with some hunting applications where deep penetration and minimal expansion are desired.

Sierra Bullets Full Metal JacketFull Metal Jacket (FMJ) is a traditional design configuration featuring traditional Sierra accuracy and quality. Designed for flawless feeding characteristics in semi-automatic pistols, it is also recognized for its deep penetration due to its heavy jacket. Although nose configurations and ogives were designed for positive feed in auto-loading pistols, Sierra's strict quality control and dimensional controls result in an exceptionally accurate bullet. Unlike other FMJ designs, the Sierra bullet is capable of match accuracy as well as flawless feeding for the utmost in shooter confidence. It is an excellent choice for combat or speed type competitive shooting situations.

Selecting the Appropriate Bullet
When selecting a match bullet for target competition, there are two paramount technical considerations: the maximum accuracy that a match rifle can deliver and crosswind deflection. Rifles are individuals also. One rifle may deliver fantastic accuracy with a particular bullet in a particular cartridge, but another rifle shooting the same cartridge with the same bullet may not deliver acceptable accuracy. This is why Sierra offers a number of MatchKing bullets in most calibers, sometimes differing by only a few grains in weight. The best bullet for maximum accuracy in any particular rifle and cartridge can be selected only by testing. Experienced target shooters know that they must try different bullets and often different loads (powder and primer) behind each bullet.

A bullet's deflection in a crosswind depends on two factors: the muzzle velocity and the ballistic coefficient of the bullet being fired. For muzzle velocities above 1600 fps, crosswind deflection decreases as muzzle velocity increases. Crosswind deflection always decreases as bullet ballistic coefficient increases. For almost all the MatchKing bullets in each caliber, ballistic coefficient increases with bullet weight. So, if there were no other considerations, we would choose the heaviest MatchKing in each caliber and shoot it at the highest possible muzzle velocity.  However, this is not always possible because of powder capacity and/or chamber pressure limits. With a big magnum case, we often can minimize crosswind deflection by using the heaviest MatchKing bullet in that caliber and load it to the highest possible muzzle velocity. However, large, heavy bullets always reduce the powder capacity of any case. Chamber pressure limits often restrict the selection of powders, so that full flexibility to achieve high muzzle velocities is just not possible. With many cartridge cases, we simply cannot fire heavier bullets with enough muzzle velocity to minimize crosswind deflection. A lighter bullet with lower ballistic coefficient but fired at higher velocity sometimes has less crosswind deflection.

This is where an exterior ballistics computer program, such as Sierra's Infinity program, can greatly aid the target shooter. The shooter can test the crosswind deflections of different candidate bullets and loads with this program. This approach might not lead to the best bullet selection, but it may reduce the number of bullet and load combinations the shooter must try on the shooting range.

Selecting a bullet for hunting is considerably different. Several variables are involved in most hunting situations, and these strongly influence bullet selection. The first considerations are what type of game will be hunted (varmints, small game, medium game or large game) and what rifle/cartridge combination will be used. When going after varmints or small game and shooting a rifle in a smaller caliber, shooters may want a bullet that expands explosively for instant kills. However, if shooters want to preserve the pelt of a small animal for mounting or selling, they may want a bullet that does not expand, leaving small entry and exit wounds.

When preparing to hunt medium game (deer, antelope, sheep, mountain goats, etc.), hunters might be using a rifle in 6mm, 25, 6.5mm, 270, 7mm, or 30 caliber, or even the venerable 45-70. In this case, a bullet that penetrates light bones and expands in flesh to produce a wide wound channel is needed.  To go after heavy game on the North American continent (buffalo, elk, moose or bear), or heavier medium game on the African continent, shooting a rifle chambered for a larger caliber may be preferred.  These situations require a bullet that smashes through large bones and expands reliably in flesh to produce a very large wound channel.

These characteristics will help guide bullet selection. Generally, sub-MOA accuracy is not required for hunting, except possibly for small varmints (ground squirrels, prairie dogs, etc.) at long ranges. But of vital importance will be the velocity, retained energy, penetration and expansion properties of the bullet and cartridge for your intended game animals.

Other factors that affect bullet selection include the distance of the shot, the altitude, and the terrain and foliage. For example, if hunting deer in a thickly wooded area in which the range distance of a shot is likely to be less than 200 yards, a round nose or flat nose bullet would be a good choice. These bullets have excellent penetration and expansion on medium game. Typical cartridges firing these bullets can have maximum point blank ranges exceeding 200 yards for deer-sized game. Note that firing at game through grass, leaves or brush is never recommended, because any bullet is likely to be deflected.

When hunting deer or antelope in open areas where the range of a shot might be several hundred yards, selecting a bullet with a higher ballistic coefficient would be beneficial to help retain velocity, energy, and penetration downrange. Ideal choices would be a spitzer flat base or spitzer boat tail bullet. If distances are limited to around 300 yards, a hollow point boat tail bullet could be a good selection. If crosswinds are likely to exist, the ballistic coefficient should be high, because a high ballistic coefficient will reduce crosswind deflection.

Hunting medium game in mountainous territory, where shooting across ravines, or at steep uphill or downhill angles, high ballistic coefficient and terminal velocity will be important in bullet selection. In such territory, there are likely to be both cross and vertical winds, which will deflect bullet trajectories. Shooting up or down hill will cause the bullet to impact high. Once again, a combination of high ballistic coefficient and high velocity will minimize these effects.

Hunting at high altitude can have advantages. The thinner air offers less resistance and bullets will experience a slight increase in retained velocity and energy. 

These are just a few comments illustrating the thought process required to select a bullet.  Shooting conditions and prior experiences are important factors in deciding which bullet is best for the individual situation.  Regardless of your needs, Sierra offers an extensive variety of bullets for your hunting and shooting requirements.

Who is MDT?
Modular Driven Technologies, like Lockhart Tactical, they're Located in BC, Canada.

Modular Driven Technologies Corp. (dba MDT Corp.) was founded in 2009. With input from a number of tactical competition shooters, F class shooters and others, MDT launched their first chassis; the TAC21. This revolutionary, 100% made in Canada, chassis which accepts any AR-15 buttstock and pistol grip, increases accuracy by as much as 28%!

Their manufacturing facilities are located in Chilliwack BC, Canada.

Over the last few years more chassis systems and other firearm accessories were added to the product line, and the company has grown to be a leader in the marketplace for manufacturing chassis systems for precision rifles. Our products are used by many shooting sports enthousiasts, Law enforcement and Military personel.

Our specialty is finding needs in the marketplace, and filling those gaps. We also manufacture products for other companies who need our knowledge in manufacturing and engineering. You can pick up their full array of products from Lockhart Tactical.

Whats a Chassis and why do I need one?
A chassis is the rifle component that holds the barrel, action, trigger group, grip, buttstock and accessories. You could say its the frame. Similar to a vehicle. The frame of the vehicle is what the engine, all body panels, seats ad more are bolted to. If you have a weak frame, no matter how good your engine is, your vehicle is going to have serious problems!


It must be strong enough to hold all the rifle components and not flex or come into contact with any part of the barrel when rested on any surface. A great chassis should also be light enough that you can packing it around with you all day if needed. Have you ever heard the term "free floating barrel"? This simply refers to the firearm barrel and weather or not it can ever come in contact with the chassis. A free floating barrel is optimal. All of our MDT chassis's feature free floating barrels. This is a must have for the precision shooter / hunter. If the barrel is not free floating, every time you touch the hand guards, you may actually be flexing the chassis a bit and causing it come into contact with your barrel. Contact between the barrel and anything else can change the barrel harmonics which can drastically change your bullets point of impact (POI) from your intented point of aim (POA).

From the moment that you pull the trigger and the firing pin strikes the primer, until the bullet leaves the muzzle, a series of vibrations begin in the rifle. All of these vibrations are transmitted to the barrel in various magnitudes. These include minor things as; the trigger sear releasing the firing pin, the firing pin moving forward, striking the primer, and the cartridge being moved forward. The powder then begins to ignite, and the bullet starts moving forward and engages the rifling.

Because of the twist of the rifling, the bullet while it is being propelled forward, begins to spin imparting a small but measurable torque, but more importantly as it traverses the barrel it also sets up a circular vibrational pattern, or arc. The heat of the burning powder along with the pressure wave generated by the expanding gasses start another vibrational pattern that is induced into the barrel. All of these movements cause the barrel to stress and vibrate with a number of different harmonic patterns which if not controlled by some means cause each projectile to leave the muzzle at a slightly different point in the vibrational arc.

Some people speak about the "whip" of the barrel, which would imply to some, that the barrel simply vibrates up and down. Although there are some of the vibrations that are traveling in this direction, the main vibrations are circular. If this were not true, then a 3 shot group from a rifle would always be in a vertical string. This would be because, one would leave at the bottom of the "whipping action", one would leave from the center and one from the upper travel of the "whip". As we all know this seldom occurs, and if it does, it is usually caused by the barrel being under a heavy stress, such as way to much pressure exerted against it, caused by improper bedding of the barrel (not free floating).

Most 3 shot groups you will see will be virtually triangular in shape, this is caused because as the barrel vibrates through its "circular arc" one bullet leaves the muzzle at say 12 o’clock, another at say 4 o’clock and the third at maybe 8 o’clock. The larger the arc of the barrel, the less accurate the rifle will be, and the larger the triangle. As a rule the less mass a barrel has, (the thinner) the more it is affected by the vibrations, this is the reason that a "heavy" barrel seems to shoot more consistently than a sporter barrel.

 Precision Vs Accuracy

The two biggest key factors of repeatability is accuracy and precision.
If you're a professional pilot, but the plane won't fly, you won't have much luck doing your part of the process. The same goes for a firearm. Having a quality chassis, barrel and action, trigger group and optic are all crucial parts of building a solid rifle. Without that, no matter how much effort you put into learning how to shoot professionally, you simply won't  be able to acheive more than the firearm's limit. You need each shot to land in the same place. Once a rifle is built properly, a new shooter should be able to fire the rifle and expect good results. This takes care of the precision part of shooting; Its the firearm itself.

Once the precision factor is addressed, the hardest part of shooting boils down to operator skill. Accuracy is a skill which is build on experience behind the trigger and learning to read your surrounds (wind, temperature, etc). Once that is mastered, you'll be hitting the V bull time and time again. The ergonomics of the chassis will help you acheive accuracy. The more comfortable, and easy your rifle is to use, the better you'll do with it. Period.

MDT Lockhart

MDT Timeline

The TAC21, named Tactical (21st Version) brought style, ergonimics and increased to the market. Its beefy, stable and well weighted design makes it a perfect fit for tactical shooters, military and police agenices, as well as F class shooters.

The LSS (Light Sniper System) and LSS-XL (Light Sniper System Extra Large) came right after the TAC21 offering a lighter, more compact shooting chassis. These are perfect for both short and long barreled rifles. Weighing between 1.6lb and 2.1lb depending on size, it is one of the lightest, strongest chassis around! If you're a hunter or target shooter this is the chassis for you! The XL version is the exact same in all aspects except for length of the foreend and the buttstock connection. The LSS is for carbine stocks and the LSS-XL is for fixed stocks, but we do sell the adapter required to change it.

After the LSS duo were released, MDT prepared their HS3 - Hunter Sniper Three (3rd chassis MDT made). This was build for the avid hunter. The HS3 is a light (2.2lb) chassis system for bolt action rifles that allows use of fixed buttstocks and grips to suit your needs. It is machined from 6061 aluminum, hard anodized and finished with black or FDE side panels for color, grip and feel. It has the same length foreend as the LSS-XL an allows you to swap out different colored side panels to match your enviroment even better!

Everyone has a 22! But no one made a ultra high end chassis for them. Stepping up to the plate once again, MDT launched their LSS-22 (Light Sniper System for 22's). You guessed it! It's the same incredible chassis but scaled down slightly to fit the 22 caliber world.

in January of 2017, MDT launched their 6th chassis called the ESS (Elite Sniper System). This chassis is by far their most impressive, allowing users to totally customize their stock. You get to choose from nine (9) different foreends, ensuring this chassis fits your needs exactly. The foreend options are No rail in three lengths, NV rail in three lengths and the full rail in three lengths. The chassis body is unlike anything else, a built in serrated barricade stop has been added to the front of the magazine well and a polymer fore-end grip at the balance point adds comfort. Thumb shelves have been added to both side of the chassis for shooters who prefer an open grip. The ESS comes with a proprietary buttstock and MDT will have a folding apapter and AR15 style adapter in the upcoming summer of 2017.

There is more to building a firearm than just a chassis. You'll need some magazines, a pistol grip, a buttstock and an optic for sure. Other parts you may want would be picatinni rails which allow you to add other accessories such as a bipod, a sling slud or a flashlight. MDT offers a wide array of accessories to finish most of your build. For everything else, there is Lockhart Tactical. Luckily, we carry it all to make it easy for you. See MDT's accessories here

 

MDT is also excited to announce their new minimalsitic modular buttstock the Skeleton Carbine Stock. The Lite buttstock will retail for only $219, while the adjustable version will sell at $249.99. Four (4) different custom lengths of beefed buffer tube and stocks will be available to pair perfectly with all shooters. These stocks will now also fit the LSS series chassis without the need for an additional adapter.
