Hk Mr762 A4 7.62x51 16.5" 10rd Blk

The Heckler & Koch MR762 A4 is a semi-automatic rifle chambered in 7.62×51 NATO (.308 Winchester) that delivers precision and reliability in a modern modular platform. Built on the proven architecture of H&K's military-grade engineering, this rifle features a 16.5-inch barrel with a matte black finish and ships with one 10-round magazine, making it compliant for restricted jurisdictions while maintaining the full power of the .308 NATO cartridge.

The 16.5-inch barrel length balances velocity retention with handling efficiency—7.62 NATO achieves approximately 85–90% of its full-length rifle velocity in this configuration, preserving effective range to 600 meters while keeping the overall package maneuverable in vehicle and structure entry scenarios. The A4 configuration provides a standardized upper receiver that accepts AR-platform optics and accessories, giving operators the flexibility to configure the rifle to specific mission requirements. The matte finish resists glare and corrosion, essential for weapons maintained in variable field conditions.

The MR762 A4 suits law enforcement tactical teams, military designated marksmen, and civilian shooters who require a .308 semi-automatic platform with factory reliability and modularity. The 10-round magazine capacity meets restrictions in states with standard-capacity limitations while delivering sufficient firepower for intermediate-range engagements. Users value H&K rifles for consistent out-of-the-box accuracy, minimal maintenance overhead, and parts durability in high-round-count training cycles.

In the semi-automatic .308 market, the MR762 occupies the premium tier—comparable to AR-10 variants but with tighter manufacturing tolerances and factory-integrated ergonomics. The AR-pattern upper makes it compatible with standard mounting systems and optic footprints, lowering the total system cost once integrated into an existing infrastructure.
