THE MDT LSS GEN2 CHASSIS SYSTEM
Replace your factory rifle stock with the MDT LSS Gen2 Chassis System. This light and compact, tactical rifle chassis is designed to convert your rifle into an external box magazine fed system, capable of utilizing AR15 buttstocks and grips.
Simple drop-in installation means there’s no need to visit a gunsmith, swap out the factory rifle stock for this aftermarket stock in minutes.

FREE FLOATING BARREL
Your barrel, after placing your action into an MDT Chassis, does not touch the chassis at any point along its length. This ensures that it is free to move naturally during the shot without any interference from the rifle stock, creating a much more consistent and accurate rifle.
AICS MAGAZINE COMPATIBLE
Converts your rifle into an AICS detachable box magazine system, allowing the use of all AICS compatible magazines. An ambidextrous magazine latch and side-relieved magazine well ensure reliable and consistent use.

WHAT YOU GET, AND WHAT YOU NEED
The LSS Gen2 chassis system comes as a 1-piece chassis, with all required mounting hardware included. This includes new action screws, and a screw for the pistol grip.
To complete this chassis on your rifle, the additional items you need to purchase are:
- Any standard chassis buttstock.
- A buffer tube for your buttstock. (Both mil-spec and commercial work on our chassis) NOTE: If you purchase an MDT buttstock this includes the buffer tube so you won’t need to purchase an additional one.
- An AR15 Pistol Grip. For fixed interface chassis, a grip without a beavertail, or with a soft (bendable) beavertail must be used.
- At least one magazine
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 MDT Polymer magazines and MDT Poly Metal 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.
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
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 this magazine http://shopruger.com/556-NATO-10-Round-Magazine/productinfo/90458/Does not work with 300 Blackout
It will fit Predator and Ranch versions. Please read notes on magazines for 223/556 rifles.
RUGER M77 (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 AICS compatible steel magazines made for the 223 cartridge.
