LMT MARS-H Shovelnose MRP 7.62x51mm SBR 13.5" Barrel - 20 Rd

Engineered for elite military, law enforcement, and precision marksmen who require modular versatility and true monolithic rigidity, the LMT MARS-H MRP-H M-LOK "Shovelnose" Piston Rifle (13.5" 7.62x51 / .308 Win) sets the standard for modern heavy-caliber battle rifles. Built on Lewis Machine & Tool’s patented Monolithic Rail Platform (MRP™), the upper receiver is CNC-machined from a single solid forging of aerospace-grade aluminum. Its unique "Shovelnose" profile and patented two-bolt locking interface engage the barrel extension across a full 360 degrees, allowing operators to change barrels of varying lengths and calibers in seconds while guaranteeing a true return-to-zero.

Driven by a clean-running short-stroke piston operating system and a full-auto rated piston bolt carrier group, this 13.5-inch NFA short-barreled rifle configuration features a chrome-lined chromoly barrel with a 1:10" twist rate for stabilizing heavy 7.62 NATO / .308 projectiles. The rifle is built around the fully ambidextrous MARS-H forged lower receiver, outfitted with LMT’s AXLE Euro two-stage trigger, a dry-film lubricant coated buffer tube, an endplate with QD swivel port, a winter trigger guard, an ergonomic textured grip, and a collapsible SOPMOD stock. Delivering exceptional control and gas management, the rifle comes complete with a 20-round magazine and three M-LOK rail panels.
