MDT LSS-XL Gen 2 Chassis System

The original LSS-XL Gen2 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 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 five sides of the forend
  • Barricade-stop grooves ahead of mag-well
  • Side-relieved mag well to accommodate bulging magazines
  • Carbine and fixed buttstock interface options

All Chassis Systems now come with a MDT Pistol Grip.

Please note: Some action inlets, left handed models & colours will be special order and have extended delivery times.

Product Description

Increase accuracy and ergonomics of your rifle with our LSS-XL Gen2 chassis system. The LSS-XL Gen2 is a longer and more feature-rich version of our 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 LSS-XL Gen2 comes in a FIXED or CARBINE option depending on buttstock preference. Read more information about FIXED and CARBINE interfaces. 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.

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.

LITHGOW 102 SA

For .223 models the bolt stop may be too long. 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.

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:

  • 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
