Heckler & Koch USA MR556 A4 & MR762 A4

Heckler & Koch, the global leader in small arms, is excited to announce the release of the new MR A4 Series. The MR556 A4 and MR762 A4 are the latest products released by HK-USA.

The A4’s updated furniture and fully ambidextrous controls make it more user-friendly than ever. A new lifetime barrel bore guarantee, an HK first, reflects HK’s confidence in this no-compromise civilian product.

“Our testing has shown our proprietary cannon-grade steel barrels vastly outperform so-called mil-spec barrels in both accuracy and durability. We’re so confident in our barrels that we now guarantee them for life. You shoot it out, we’ll replace it. Period.”

Nathan Shueth, HK Director of Business Development

Schueth said HK tested the MR556 A4 head-to-head with a with a mil-spec chrome-lined barrel to compare accuracy and durability. After 12,000 rounds, the HK experienced no degradation in accuracy, while the mil-spec competitor was shooting groups 2.5X larger than its baseline.

The updated MR rifles are feature-rich and now reflect the latest technologies included in the newest models of the select-fire HK416 and HK417 they are patterned after. A few key updates include a 2-position adjustable gas block for shooting suppressed or un-suppressed, a new fully ambidextrous lower receiver (bolt catch/release, magazine release, 45-degree selector levers) and new slimline handguard and buttstock. At launch, the MR556 A4 will come in two barrel lengths: a 11.5 in. pistol configuration, and a 16.5 in. Rifle. The MR762 A4 will ship with a 16.5 in. barrel.
