The latest update from HK-USA to the commercial variant of the legendary HK417, the MR762 A4 represents an enhanced example of “no compromise” HK performance.

Chambered in 7.62 x 51mm, its short-stroke gas piston operating system does not impart hot carbon fouling back into the action, allowing the weapon to run longer, with less maintenance and with less wear on internal components than direct-impingement ARs. Its adjustable gas regulator allows the operator to tune the action specifically for suppressed or unsuppressed operation. Fully ambidextrous controls, lighter weight and a slimmer profile make the new A4 easier to operate, manipulate and employ. For those who demand an AR with unmatched capability and uncompromising reliability and durability, the MR A4s remain the top tier solution.

The MR762 A4 is built on HK’s proprietary short-stroke gas piston operating system, which ensures reduced fouling and heat transfer, resulting in reliable performance even in adverse conditions. Its cold hammer-forged barrel is known for superior accuracy and longevity, while the free-floating handguard allows for enhanced customization with M-LOK-compatible accessories. Designed with user adaptability in mind, the rifle features fully ambidextrous controls, including a safety selector and magazine release. Its optics-ready platform provides the flexibility to install a wide range of scopes and sights, ensuring it meets the needs of precision shooters.
