Increase accuracy and ergonomics of your rifle with LSS-XL Gen2 chassis system. The LSS-XL Gen2 is a longer and more feature-rich version of LSS chassis system. The LSS-XL Gen2 has been updated with a bold, modern new look inspired by the popularity of the ESS chassis line, while maintaining and improving upon the overall aesthetic of an MDT chassis.
The LSS-XL Gen2 allows you to convert your bolt action rifle to a highly versatile rifle allowing you to adjust the ergonomics with the use of AR-15 buttstocks and grips, and at the same time converting it to an external box magazine fed rifle.
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 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.
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, MDT long action chassis use 3.715 length magazines.
The chassis will accept recoil lugs up to .350" (8.9mm) thick.

WHAT YOU GET, AND WHAT YOU NEED
The LSS-XL 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 AR-15 buttstock.
- A buffer tube for your buttstock. (Both milspec and commercial work on the chassis)
- An AR-15 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 actions
Only MDT 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 MDT Metal 3.560 magazine will fit with the chassis for this action and needs to be purchased separately.
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.
