H&K MR556A1: Battlefield-Proven Excellence with Heckler & Koch's Legacy

Freedom Weapons is thrilled to showcase the H&K MR556A1, a commercial carbine that's a direct descendant of the globally acclaimed HK416. This rifle embodies the unparalleled reliability, durability, and precision that's synonymous with the Heckler & Koch name.

Assembled in the USA, the MR556A1 harmoniously blends US and German-made components, leveraging many of the same parts and assemblies that the HK416 is renowned for. Unlike the conventional direct-gas-impingement system found in many AR15-style rifles, the MR556A1 boasts HK's proprietary short-stroke gas piston. This "closed" piston system ensures that exhaust gases never enter the receiver, resulting in a cooler, cleaner, and more reliable operation. Especially under challenging conditions like dust, sand, and mud, the superiority of the HK system becomes evident, a testament to why the world's elite military and law enforcement units place unwavering trust in their HK firearms.

The MR556A1's barrel stands out, cold hammer-forged from the finest cannon-grade steel. With a 1 in 7” twist and a unique taper-bore configuration, it promises enhanced accuracy and velocity. HK's meticulous manufacturing processes, including their renowned cold hammer forging, ensure a barrel that not only exceeds "mil-spec" standards but also offers exceptional durability and precision. The same grade steel used in cannons is employed here, with a design that contributes significantly to its unparalleled accuracy.
