HK Unveils the MR A4 Series

Heckler & Koch, the iconic name in small arms innovation, has dropped a bombshell that’s set to shake up the firearms world. Introducing the all-new MR A4 Series—featuring the MR556 A4 and MR762 A4—designed to elevate your shooting experience with uncompromising performance and cutting-edge features.

Why This Release Is a Game-Changer

HK-USA has outdone itself with the MR A4 lineup. Think next-level user-friendliness with fully ambidextrous controls and upgraded furniture that screams versatility and comfort. And here’s the jaw-dropper: HK is backing these rifles with a Lifetime Barrel Bore Guarantee—an industry first! This is HK’s ultimate mic drop, showcasing their unmatched confidence in delivering superior civilian firearms.

“Our barrels don’t just last—they dominate,”

says Nathan Schueth, HK’s Director of Business Development. HK’s proprietary cannon-grade steel barrels crushed the competition in rigorous testing. After firing a grueling 12,000 rounds, the MR556 A4 still shot like it was brand new, while the mil-spec barrels were spraying 2.5X wider groups. If you shoot out your HK barrel? They’ll replace it. No questions asked. Period.

Features That Set the MR A4 Apart

The MR556 A4 and MR762 A4 pack features inspired by the legendary HK416 and HK417, with updates that hunters, competitors, and tactical enthusiasts will drool over:

  • 2-Position Adjustable Gas Block for seamless suppressed and unsuppressed shooting.
  • Fully Ambidextrous Lower Receiver, featuring bolt catch/release, mag release, and 45-degree selector levers—built for any shooter, lefty or righty.
  • Sleek New Handguard and Buttstock for a modern, ergonomic fit.
  • Available barrel configurations to suit your needs:
    • MR556 A4: 11.5-inch pistol or 16.5-inch rifle.
    • MR762 A4: 16.5-inch rifle.

Mark Your Calendars

The MR556 A4 starts shipping to HK Dealers on November 25th, 2024. Ready to upgrade your gear? Find your local HK Dealer here: HK Dealer Locator

This is more than a rifle—this is HK redefining what’s possible. Whether you’re hitting the range, taking on big game, or gearing up for the ultimate hunt, the MR A4 Series is ready to deliver unmatched performance, round after round. What are you waiting for? Gear up and own the best!
