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 the MDT LSS chassis system. The LSS-XL Gen 2 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.

DETAILS

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 barreled rifles. Many customers liked the LSS chassis, but wanted to use a fixed buttstock, and get their bipod out further forward. 

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

The Gen2 lineup incorporates the following new features:

• Bold, modern new look

• Ambidextrous magazine release

• Thumb rest 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 fore end

• Barricade-stop grooves ahead of mag-well

• Side-relieved mag well to accommodate bulging magazines

• Carbine 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.
