LMT MARS-H CQB 7.62×51 NATO – Built for Precision, Ready for War
The MARS-H CQB brings serious firepower in a compact, adaptable package. Chambered in 7.62x51 NATO with a 16" chrome-lined 1:10 twist barrel, this semi-auto rifle delivers long-range precision with battle-proven reliability.

At its core is the LMT Monolithic Rail Platform (MRP)—the only true monolithic upper on the market, milled from a single solid aerospace-grade aluminum forging. The MRP design allows for fast, toolless barrel swaps with guaranteed return-to-zero performance—making it a true multi-mission platform.

This rifle includes a CQB MWS 12.5” upper receiver, MARS-H ambidextrous lower, S-A bolt carrier group, and a proprietary low-profile gas system designed for maximum durability. The two-stage trigger, ambi controls, and SOPMOD stock round out a feature set built for shooters who demand versatility without compromise.
