HK 81000829 MR762 A4 7.62x51mm 20+1 16.50" Black Threaded Barrel, Black Picatinny Rail, M-LOK Handguard, 9 Position Black Synthetic Stock, Black Finger Grooved Grip, Ambidextrous

The latest MR762 A4 represent an enhanced example of "no compromise" HK performance. 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. Its adjustable gas regulator allows the operator to tune the action specifically for suppressed or unsuppressed operation. While fully ambidextrous controls, lighter weight and a slimmer profile make the new A4 easier to operate, manipulate and employ.
