HK 81000827 MR556 A4 5.56x45mm 30+1 16.50" Black Threaded Barrel, Black Picatinny Rail, M-LOK Handguard, 6 Position Black Synthetic Stock, Ambidextrous
The MR556 A4 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.
Fully ambidextrous controls, lighter weight and a slimmer profile make the new A4 easier to operate, manipulate and employ.
