MR556 A4 | 11"

The latest update from HK-USA for the commercial version of the legendary HK416, the MR556 A4, is a great example of HK's uncompromising performance.

Chambered in 5.56 x 45 mm, the short-stroke gas piston system prevents hot carbon deposits from entering the mechanism, ensuring the rifle runs longer, requires less maintenance, and experiences less wear on internal parts than direct-impingement ARs. The adjustable gas regulator allows you to tailor the mechanism specifically for use with or without a suppressor. Thanks to fully ambidextrous controls, reduced weight, and a sleeker design, the new A4 is easier to operate, handle, and deploy.

For anyone looking for an AR rifle with unmatched performance and uncompromising reliability and durability, the MR A4 remains the top choice.
