The LMT Defense MARS-H MRP-H stands as a premier 7.62x51mm battle rifle, engineered for shooters who demand uncompromising performance, modularity, and ambidextrous control. Built around LMT's patented Monolithic Rail Platform (MRP-H), this rifle features a true monolithic upper receiver milled from a single aerospace aluminum forging. It delivers exceptional rigidity, heat dissipation, and return-to-zero barrel swaps in seconds thanks to the innovative side-accessible locking bolts that engage the barrel extension a full 360 degrees. Chambered in powerful 7.62x51mm NATO with a 16-inch chrome-lined barrel (1:10 RH twist), the MARS-H combines the robustness of a combat-proven system with the precision of a long-range rifle. It includes a two-stage trigger, ambidextrous lower receiver with fully ambidextrous controls (bolt catch, magazine release, and safety), ergonomic textured grip, SOPMOD stock, and extensive M-LOK attachment points across seven sides plus a continuous 19.25-inch Picatinny rail on top. Cryogenically treated barrels with proprietary coatings ensure long-term durability under sustained fire. Whether used for duty, competition, or serious recreational shooting, the MARS-H MRP-H offers unmatched versatility. One receiver accepts multiple barrels of varying lengths, materials, and even calibers while maintaining sub-MOA potential with quality ammunition. Complete with one magazine, owner's manual, and rail panels, this rifle represents the flagship of LMT's MARS-H lineup. Ready to own one of the most advanced .308 battle rifles available?
