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.

PLEASE READ! If you are shopping for firearms, this is important!
Please make sure the rifle or shotgun you are looking to purchase is a California complaint. Firearms listed with a 10-round magazine doesn’t mean it is California complaint. Typically, for AR or AK series of rifles, there is a “CA” designation added to the part number which can be an indicator it is legal to be sold in California. All AR-15 rifles need to be featureless or break action and AK-47 rifles need to be featureless or fixed magazine. If you have any questions on making your purchase, feel free to call our helpful firearms consultant at 619.564.6965. We also have our retail store open 7 days a week!
