Key Features and Mechanical Advantages

Short-Stroke Gas Piston System

HK’s proprietary short-stroke gas piston operating system reduces fouling and heat transfer into the receiver and bolt carrier group. That means extended reliable operation in extended strings of fire and in harsh environments where direct impingement systems tend to degrade faster.

Barrel and Accuracy

The cold hammer-forged 16.5″ barrel is engineered for durability and repeatable accuracy. Chambered for .308 Winchester/7.62 NATO, the MR762A4 provides excellent terminal performance and long-range capability with commonly available match and duty-grade ammunition—ideal for precision rifle roles and tactical engagements.

Modularity and Controls

With a free-floating handguard that accepts M-LOK accessories, shooters can tailor handstops, lights, bipods, and backup sights. Fully ambidextrous controls—safety selector and magazine release—allow intuitive handling for left- and right-handed operators. The optics-ready receiver accommodates a wide range of scopes and red-dot solutions.

For those evaluating build quality and system reliability, the MR762A4 represents Heckler & Koch’s commitment to mission-capable semi-auto platforms. View product details and pricing to compare configurations and finalize your purchase.
