HK MR556 A4 556NATO 16.5″ 30RD BLK
Out of stock
The HK MR556 A4 is a commercial variant of the legendary HK416, offering enhanced performance and reliability. This rifle features a 16.5-inch barrel and a 30-round capacity, chambered in 5.56 NATO. The short-stroke gas piston operating system reduces hot carbon fouling in the action, allowing for longer operation with less maintenance than traditional direct-impingement systems. An adjustable gas regulator enables tuning for both suppressed and unsuppressed use. Fully ambidextrous controls, a lighter weight, and a slimmer profile make the MR556 A4 easier to handle and operate, making it a top-tier choice for those seeking unmatched capability and reliability.
Available from ICB Firearms, with fast nationwide shipping and local pickup in Saint Clair Shores, Michigan.
