HK MR556 A4 Pistol
H&K MR556 A4 5.56mm Pistol
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. While fully ambidextrous controls, lighter weight and a slimmer profile make the new A4 easier to operate, manipulate and employ.

HK MR762 A4
HK MR762 A4 Overview and Specifications
The HK MR762 A4 is a high-performance 7.62 NATO/.308 semi-automatic rifle, celebrated for its precision engineering by Heckler & Koch. It’s outfitted with advanced features, making it a premium choice for professional shooters, law enforcement, and enthusiasts. Introducing Heckler and Koch’s all new MR762, the HK MR762 A4 Gas Piston 7.62/308 AR10 Rifle with new M-LOK Rail and adjustable two-way gas block. The HK MR762-A4 308 AR10 Semi Auto Rifle is out fitted with Heckler and Koch’s new cold hammer forged cannon grade steel 16.5-inch barrel. HK did a head-to-head 12,000-round barrel test between a Mil-spec chrome-lined barrel and their new cannon-grade steel barrel. Their new cannon-grade steel barrel outperformed the Mil-spec chrome-lined barrel in both accuracy and durability. After 12,000 rounds the Mil-Spec chrome lined barrel groups opened up 2.5 times larger than its starting base line and the HK experienced no degradation in accuracy. Furthermore, HK stands behind their new barrel so much, that the HK MR762-A4 7.62 AR-15 Rifle comes with a lifetime barrel warranty, so if you shoot out the barrel they will replace it for free.

After 7 years of intense development, H&K enters the world of concealed and everyday carry with the CC9. Unlike all of H&K’s other firearms that were designed for law enforcement and military applications, the CC9 was designed exclusively for the U.S. civilian market and is 100% American made. During its development, this compact handgun underwent the same intense trials as H&K’s USP and meets the demanding NATO AC/225 specifications. The CC9’s barrel is hammer forged and uses polygonal rifling, giving the CC9 outstanding close range accuracy and an exceptionally long barrel life. Accuracy is further enhanced thanks to a high visibility front sight with a tritium insert paired with a blacked out rear sight, and the slide is cut to accept red dot sights. Despite its small size, the CC9 doesn’t have the “snappy” recoil common amount pistols of a similar size thanks to superb ergonomics, and comes standard with a full set of ambidextrous controls.
