MDT LSS-22 22LR RIFLE CHASSIS SYSTEM

The Modular Driven Technologies MDT LSS-22 Chassis System for .22LR caliber rifles is lightweight and compact, and adopts the same footprint as the centerfire MDT LSS Chassis. You will notice a significant improvement in accuracy due to the V-shaped bedding and free floated fore-end, which allows for barrel contours up to 1″ in diameter.

The LSS-22 Chassis System is manufactured out of billet 6061-T6 aluminum, and has been finished with Cerakote™ in Black or Flat Dark Earth (FDE).

To keep this chassis system compact, MDT has designed designed the rifle chassis to take collapsible AR-15 buttstocks. Fixed buttstocks can also be mounted with the use of a fixed stock adapter.

The LSS-22 uses your factory magazine and each chassis is compatible with all factory barrel contours.

Because we have lowered the buttstock interface, The Savage Mark II, CZ 455 and Ruger American are able to use iron sights with this chassis. If you are using a scope, we recommend a stock with a cheek riser. Visit Modular Driven Technologies

MDT LSS XL Chassis Details

The original LSS-XL chassis system was designed as a variant of our highly popular LSS chassis. The LSS chassis was designed for use with compact, short barrelled rifles. Many customers really liked the LSS chassis, but wanted to use a fixed buttstock, and get their bipod out further forward.

This prompted us to design the first-generation LSS-XL chassis system, which has a forend extended by 3″ and was designed to accept fixed rifle stocks without the need of using any adapters.

After the successful launch of our ESS chassis system, requests started pouring in for the new features that had been introduced on the ESS chassis to be rolled out on our other chassis systems. In response, we have upgraded our LSS-XL chassis line with a Gen2 lineup that incorporates the following new features:

  • Bold, modern new look
  • Ambidextrous magazine release
  • Thumbrest above trigger guard
  • Larger barrel channel to accommodate barrels up to the diameter of the action
  • M-Lok pattern attachment slots on all 5 sides of the forend
  • Barricade-stop grooves ahead of mag-well
  • Side-relieved mag well to accommodate bulging magazines
  • Collapsible and fixed buttstock interface options

The chassis is designed with V-shaped bedding surfaces, allowing you to drop your rifle right in without the need for additional bedding. The bottom profile of the V-block cutout has been kept round and close to the action without making contact, maintaining maximum strength. The LSS-XL Gen2 chassis will free float barrels up to 1.350” diameter.

MDT LSS XL Gen2 Mounting and Compatible Accessories

The LSS-XL Gen2 chassis are designed to accept any AR-15 buttstock and pistol grip (purchased separately), offering the option to customize from the wide variety of  Accessories available on the market.

The LSS-XL Gen2 chassis accepts AICS-pattern external box magazines, and supports installation of M-Lok patterned accessories along the forend.

Note: Long action magazines come in 4 different lengths: 3.560”, 3.715″, 3.775″ and 3.850″. Unless otherwise specified, our long action chassis use 3.715 length magazines.

The chassis will accept recoil lugs up to .350″ (8.9mm) thick.

  • Increases accuracy by up to 21%
  • CNC Machined from 6061 Aluminum.

Important Notes

Howa 1500 / Weatherby Vanguard actions

Only our polymer magazines will work in the short action rifles due to the flat bottom. The long action rifles will work with the metal 3.715″ magazines without fitting.

For .223 models the bolt stop prevents the bolt from moving back far enough to pick up the rounds.  This can easily be modified by removing the bolt stop and trimming the contact face.

Savage models 10/110 11/111 12/112 16/116

For rifles with the bolt release at the bottom, the bolt release can be engaged through the side of the chassis, using a pin or tool. (Not included)

Savage Long Action in 338 Lapua Magnum

Savage Long Action chassis systems all use 3.715″ AICS magazine wells. The BA in 338 Lapua Magnum uses 3.850″ magazines and have recently switched to a thicker recoil lug which will not fit our chassis. The ESS has been specifically designed around the current BA 110 in 338 Lapua Magnum.

Tikka T3 – Long Calibers

Only our Metal 3.560 magazine will fit with the chassis for this action and needs to be purchased separately.

Ruger American

The action screw is located directly above the magazine lever. This means that the magazine lever needs to be installed AFTER installing the action into the chassis. Detailed instructions are provided, and an installation video can be found here.

Ruger American in 223/5.56mm requires the use of a magazine with extended feed lips, such as this one: http://shopruger.com/556-NATO-10-Round-Magazine/productinfo/90458/.  This is to prevent the round from being released before entering the chamber.
Does not work with 300 Blackout

This chassis will also accept the Predator and Ranch versions. Please read the notes above regarding magazines for 223/5.56 rifles.

Dimensions shown are based on Remington 700 Short Action. *Skeleton Carbine Stock show below is the 9.75″ Version

BROWNELLS MDT BRN-1 M-LOK CHASSIS

To me this is an unexpected product offering from Brownells, a Brownells branded MDT LSS Chassis. Brownells used to be slow to respond to firearm market trends and in my opinion this bolt action chassis finally shows some forward thinking on Brownells part. For me as i have stated before I really like partnerships between my favorite companies and Modular Driven Technologies and Brownells are two of my favorites. lastly i think the Rams head logo is a cool touch given that’s exactly the types of beasts that might see action from this chassis.

There are currently 18 models to choose from including two for the Ruger American Rifle. Colors are Black or Flat Dark Earth aka FDE

Whats better than a stable, accurate quality bolt action rifle that uses AR-15 or 308 AR/AR 308 magazines? I will tell you what is. The same rifle with a MDT LSS chassis. That rifle is the Mossberg MVP LC (Light Chassis). Modular Driven Technologies is soon to be a household name among rifle shooters. Mark my words.

MDT ESS CHASSIS SYSTEM | MDT RIFLE STOCK

MDT ESS Chassis Installed on a Rifle

The ESS Chassis retains the MDT proven V-block bedding system to form a solid and reliable base for the rifle action. The magazine well has been refined for easy insertion of the magazine, while reducing rattle and movement. The tab style magazine release has been replaced with a semi-flush ambidextrous paddle that can easily be activated by a weak or strong hand. The recoil lug mortise has been designed to accommodate most aftermarket recoil lugs and the trigger area will accommodate most aftermarket triggers.

MDT ESS Chassis System

A 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. The wide fore-grip area combined with the octagonal profiled for-end tube offers flexible options when shooting over bags or improvised rests. Thumb shelves have been added to both side of the chassis for shooters who prefer an open grip.

MDT ESS Chassis System Grip

The most significant change is the incorporation of the ESS specific butt-stock interface, rather than the traditional AR pattern interface.  This allows us to place the pistol grip in optimum relation to the trigger, while still allowing the shooter to choose from the wide variety of AR pattern pistol grips which suit their preference.

MDT ESS Chassis Stock – The MDT ESS chassis comes with it’s own butt-stock, similar to our Skeleton Rifle Stock. It is fully adjustable including lateral adjustment for the butt-pad and the cheek rest.  Cheek rest height and butt-pad length-of-pull are adjustable by thumb wheels.

Drake Savage Stalker 308 Long Range Tactical Sniper System at the 2015 US Army International Sniper Competition

Ft Benning, GA, 2015 US Army International Sniper Competition

SPECIAL CONGRATULATIONS TO THE US ARMY NATIONAL GUARD WARRIOR TRAINING CENTER SNIPER TEAM AS THEY HELD THEIR OWN AGAINST THE SOF TEAMS with the SAVAGE STALKER RIFLE SYSTEM

DRAKE ASSOCIATES and SAVAGE ARMS had the opportunity to provide one of the participating teams at the 2015 US Army International Sniper Competition with a new long range sniper platform – the SAVAGE STALKER 308, Drake MK12 5.56 SASS and related support equipment in cooperation with our industry partners MDT / Modular Driven Technologies, The MAKO Group/ Fab Defense.

 

During the week of October 19-23, 2015, Sniper Teams from across the world traveled to Fort Benning to compete in the Annual International Sniper Competition. The goal of this competition was to identify the best sniper team from a wide range of agencies and organizations that included the U.S. Military, International Militaries, and Local, State and Federal Law Enforcement.

Many teams were invited to compete in a gauntlet of rigorous physical, mental and endurance events that test the range of sniper skills that include, but are not limited to, long range marksmanship, observation, reconnaissance and reporting abilities, and abilities to move with stealth and concealment. After competing in the events the best teams were selected.

DRAKE ASSOCIATES and SAVAGE ARMS were privileged to be able to supply the SAVAGE STALKER 308 long range tactical sniper system, Drake MK12 5.56 SASS to the US Army National Guard Warrior Training Center Sniper team.

At the 2015 US Army International Sniper Competition awards ceremony at the end of the competition is was announced that the US Army NG WTC, using the Savage Stalker rifle system achieved the following outstanding and significant results:

  • Top National Guard Team
  • 2nd Place for NON-Special Operations/SOF team- Conventional Units

8th Place Overall Ranking for competition (The majority of the competition was from Special Operations Forces / SOF Units)

SAVAGE STALKER Rifles were very well received in the community! DRAKE ASSOCIATES had previously introduced the SAVAGE STALKER long range tactical rifles to other SOF units in recent deployments and at the USASOC Sniper Competition in March 2015 at Ft Bragg. Once again the SAVAGE STALKER Rifles were noticed and admired by the Special Operations Forces / SOF.

The SAVAGE STALKER long range tactical sniper rifles were proven to be lighter, more ergonomically designed and more accurate than many of the other systems that were used in the competition. This win by the US Army NG WTC was the result of intensive training and was a tribute to their dedication and “old school” work ethic. They competed against the best, most modern and well equipped Spec Ops teams and Won!

This is a big win for the US Army NG WTC, SAVAGE ARMS, DRAKE ASSOCIATES, MDT / Modular Driven Technologies, The MAKO Group/Fab Defense.
