Heckler & Koch MR556 A4 SBR 5.56 NATO 11" 10-Round Rifle

Heckler and Koch MR556 A4 Features The Heckler and Koch MR556 A4 SBR runs a short-stroke gas piston operating system rather than direct impingement which keeps hot carbon fouling out of the action and lets the rifle run longer between cleanings with less wear on internal components. Its adjustable gas regulator allows the operator to fine-tune the system specifically for suppressed or unsuppressed operation something direct-impingement ARs cannot match without additional parts. Chambered in 5.56 / .223 Rem the rifle cycles from a 10+1 capacity magazine through an 11 Black Phosphate threaded barrel with a 1:7 twist rate capped with an A2 birdcage flash hider. Fully ambidextrous controls a lighter overall weight of 7.67 lbs and a slimmer profile make the MR556 A4 easier to operate and manipulate than earlier HK416-derived rifles. The Black Anodized aluminum receiver carries a Picatinny rail for mounting optics while an M-LOK handguard provides mounting space for lights lasers and other accessories without adding unnecessary bulk. An adjustable black polymer stock lets shooters customize length of pull for different body types or body armor setups and the two-stage trigger offers a crisper more consistent break than a typical mil-spec single-stage trigger. Black polymer grip panels round out the ergonomics package for a secure hold under recoil. As a registered NFA short-barreled rifle the Heckler and Koch MR556 A4 SBR is available for sale at ARMSAGORA for shooters who demand top-tier reliability and performance from a compact duty-capable platform.
