JACK OF ALL TRADES
EXPOF ONEERT
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. Convert your bolt action rifle to a highly versatile rifle, allowing you to adjust the ergonomics with AR-15 buttstocks and grips, while simultaneously converting it to an external box magazine-fed rifle.
 
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.
 
The LSS-XL Gen2 comes in a FIXED or CARBINE option depending on buttstock preference.
 
COMPACT AND VERSATILE
A well rounded chassis with a slim and compact design that’s easy to transport. The perfect truck gun that can be customized and taken with you on hunts, road trips, plinking, and long hiking, you name it.
 
ROOM TO CUSTOMIZE
The MDT LSS-XL’s forend has 5 faces, each with M-LOK slots so you can attach a variety of accessories, such as rails, bipods, hoods, a spare round holder, sling mounts, and more.
 
INCREASE YOUR ACCURACY
With internal V-Block bedding keeping your action tightly secured, a free-floating barrel channel reducing vibrations, and superior ergonomic design all the way through, you can comfortably and consistently put your shots on target every time.
