MARS-H 16" Lightweight Rifle

The LMT MARS-H 16" Lightweight Rifle is a 7.62 NATO / .308 Winchester semi-automatic rifle built on the LMT Modular Ambidextrous Rifle System (MARS-H) platform. The rifle utilizes LMT’s Monolithic Rail Platform (MRP) upper receiver, which is machined from a single aluminum forging and features a continuous Picatinny top rail with M-LOK compatible attachment points for accessories. The platform incorporates LMT’s quick-change barrel system, allowing compatible barrels to be installed or removed using the receiver’s cross-bolt retention system.

This configuration includes a 16-inch chrome-lined barrel with a 1:10 right-hand twist rate and a direct impingement gas system with a low-profile gas block and straight gas tube. The rifle is equipped with the MARS-H ambidextrous lower receiver, which provides ambidextrous controls for the safety selector, magazine release, and bolt catch/release. Additional components include an LMT two-stage trigger, ambidextrous charging handle, SOPMOD stock, and M-LOK rail system for mounting accessories.
