For fixed buttstocks, you will need the fixed stock adapter,

Our MDT LSS Chassis System is onto the next generation.
The LSS Gen2 is an update of our popular LSS chassis. The LSS Gen2 chassis system now sports a bold and modern new look inspired by the contours of our more recent chassis lines like the ESS, ACC & LSS-XL Gen2, and is lighter than ever (1.4 to 1.6lb depending on the model).
The LSS Gen2 incorporates the following new features, in addition to everything the original LSS had to offer:
- Ambidextrous magazine release
- M-Lok pattern attachment slots on sides and bottom of the forend
- Barricade-stop grooves ahead of mag-well
- Side-relieved mag well
Our LSS chassis system was designed to be as compact as possible. The V-shaped bedding and free floated forend improve accuracy and ergonomics. The forend allows for barrel contours up to 1″ in diameter. The graphic on the right shows the two flat spots (V-block) where the action sits. The area below the action remains rounded to ultimate strength.
The 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, it was designed for carbine AR-15 buttstocks. However, fixed buttstocks can be mounted with the use of a fixed stock adapter. Alternatively, our LSS-XL Gen2 chassis has a longer forend and was designed to accept fixed buttstocks without the use of the adapter.
The LSS chassis is 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 chassis uses AICS style external box style magazines in .223 and .308 caliber for Short Action and .300WM or .338LM AICS style magazines for Long Action rifles, and supports the installation of bolt-on MIL-STN-1913 accessory mounting rails.
Note: Long action magazines come in 4 different lengths: 3.560″, 3.715″, 3.775″ and 3.850″. The LSS chassis for long action uses 3.715 length magazines with the exception of the Tikka T3 which needs the 3.560″ length magazines.
The max thickness of recoil lug recommend is .350″ (8.9mm)
- Increases accuracy by up to 21%
- CNC machined from 6061 aluminum
- Cerakote finish in black or flat dark earth
- Designed for carbine AR-15 buttstocks
- Accepts most AR-15 pistol grips
- Lightweight, free-floating modular forend
- Will accommodate barrels up to 1″ diameter
- Compatible with AICS style magazines in .223 or .308 (SA) and 300WM, 30.06 (LA). (Long Action magazine length 3.715)
- Weight: 1.4lb – 1.6lb
For rifles with longer barrels to be used for long range (past 900 meters) we recommend our TAC21, ESS or our HS3 Chassis systems.
Howa 1500 / Weatherby Vanguard Short Actions This is the only action that we manufacture a chassis for that has a flat bottom action. For this reason, only our Polymer magazines will work. The fitting may need to be modified slightly for proper feeding. For .223 models the bolt stop may be too long. This can easily be modified. This also means that the action does not sit in a V-Block.
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 110 in 338 Lapua Magnum uses 3.850″ magazines and have recently switched to a thicker recoil lug which will not fit our chassis. We have released a version of the ESS which is specifically designed around the current BA 110 in 338 Lapua Magnum.
Tikka T3 / T3x – Long Calibers Only our Metal 3.56 magazine will fit with the chassis for this action and needs to be purchased separately.
Savage Axis The original recoil lug that comes with the rifle is required for installation into the chassis. On the Long Action, you will need to use 30.06 3.56 Magazine
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 the #90458 Ruger Mag. Does not work with 300 Blackout
It will fit Predator and Ranch versions. Please read notes on magazines for 223/556 rifles.
Ruger Scout Drop- in for Ruger Gunsite Scout rifles only. Will not fit older Tang safety Ruger M77. Mark II and Hawkeye short action will bolt in, but modifications to the magazines and ejector may be required. Rifles with two- stage triggers will also require modifications to the chassis. The Ruger Gunsite Scout in 223/5.56mm requires the use of the #90458 Ruger Mag.
