The HK MR556 A4 Pistol with 11” CHF barrel; gas piston system; adjustable gas regulator; steel frame; custom rail system; ambidextrous safety lever; 30-round magazine; 26.5” overall length; 7.5” height; 3.07” width; and 6.61 lbs. weight.
A civilian variation of the legendary HK416, the MR556 A4 offers uncompromising accuracy, durability, and reliability; it’s simply an embodiment of precision engineering and tactical performance.
This semi-automatic pistol comes equipped with a short stroke gas piston operating system which makes the weapon run longer, with less maintenance and wear on internal components than direct-impingement ARs, because the system does not impart hot carbon fouling back into the action. To enable the operator tune the action specifically for suppressed or unsuppressed operation, this HK MR556 A4 for sale at Mister Guns also comes with an adjustable gas regulator.
More features include a cold hammer-forged barrel for enhanced precision and accuracy; a customizable, free-floating rail system which allows for the attachment of accessories like optics, grips, etc.; a 4.5 – 5.6 lb. trigger; and ambidextrous controls including a safety selector.
This firearm was engineered with premium materials for rugged performance, and, overall, its lighter weight and slimmer profile make the new HK MR556 A4 easier to operate, manipulate and employ. Bear in mind that the A4 also enjoys extensive aftermarket support, and you can get lots of great accessories, from rails and handguards all the way up to everything you need to build your own legally-registered SBR (short-barreled rifle).
