Increase accuracy and ergonomics of your rifle with the 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 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 the 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 forend extended by 3" and was designed to accept fixed rifle stocks without the need of using any adapters.
After the successful launch of the ESS Chassis System, requests started pouring in for the new features that had been introduced on the ESS chassis to be rolled out on MDT's other chassis systems. In response, MDT has upgraded their LSS-XL chassis line with a Gen2 lineup that incorporates many new features. The chassis is designed with V-shaped bedding surfaces, allowing you to drop your rifle in without the need for additional bedding. The bottom profile of the V-block has been kept round and close the action without making contact, maintaining maximum strength. The LSS-XL Gen2 chassis will float barrels up to 1.350" diameter.
The LSS-XL Gen2 CS Chassis are designed to accept Carbine Stocks and AR-15 style pistol grips, giving you the option to customize using a wide variety of accessories available on the market.
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 MDT's chassis. The ESS has been specifically designed around the current BA 110 in 338 Lapua Magnum.
Tikka T3 - Long Calibers
Only MDT's 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. Ruger American in 223/5.56mm requires the use of a magazine with extended feed lips. This is to prevent the round from being released before entering the chamber.
