LMT MARS-H 7.62 Light Battle Rifle

The LMT MARS-H 7.62 Light Battle Rifle is a semi-automatic .308 / 7.62×51 NATO rifle designed around LMT®’s patented Monolithic Rail Platform (MRP™). The upper receiver is machined from a single piece of aerospace-grade aluminum forging and features a quick-change barrel system secured by dual locking bolts with 360-degree engagement on the barrel extension. This model is equipped with a 13.5-inch lightweight chrome-lined barrel with a permanently pinned 3-prong flash hider, bringing the overall barrel length to 16 inches for compliance without additional NFA requirements.

The MARS-H platform includes a full-length 19.25-inch Picatinny top rail with M-LOK® attachment points along the remaining sides for accessory mounting flexibility. The ambidextrous lower receiver incorporates bolt catch and release, magazine release, and safety selector on both sides, along with a two-stage trigger, winter trigger guard, textured grip, and SOPMOD stock. Built for durability and modularity, this configuration supports a range of shooting applications from recreational use to professional environments.
