Its short-stroke gas piston system helps reduce carbon fouling in the action, while the adjustable gas regulator supports suppressed or unsuppressed operation. Fully ambidextrous controls complete the design. 5.0 ** ** ** ** ** [1 review](#reviews) See Price In Cart ![Credova logo](https://www.kygunco.com/brands/credova.svg) As low as **$208.15**/month with ![Credova text logo](https://www.kygunco.com/brands/credova-text.svg) ** Online In Store ** Free Shipping Enjoy delivery to the Lower 48 States at no cost. ** Ships To FFL Dealer Handled by our expert shippers in Bardstown, KY. ** Check Local Restrictions Not sure whether this item can be shipped to your area?

Item # 270652 Style HCK-81000829 UPC 642230269453 Condition New Manufacturer [HK USA](https://www.kygunco.com/brand/hk-usa) Model MR762 A4 Round Capacity 20 Caliber 308 Win Action Semi-Auto Barrel Length 16.5 in The latest update from HK-USA to the commercial variant of the legendary HK416, the MR556 A4 and 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 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 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.
