Heckler & Koch 75th Anniversary MR556A1 Semi-Automatic Rifle 5.56 NATO 16.5" Barrel (1)-10Rd Magazine Black Synthetic Adjustable Stock Tropentarn Camo Finish

As HK celebrates its 75th anniversary, there is a very limited opportunity to own a piece of our history with our 75th anniversary MR-Series rifles. Only 500 of each of these rifles will be sold. The MR762A1 rifles will be decorated in Tropentarn, the camo pattern utilized by the German armed forces or Bundeswehr. The MR556A1 is a direct descendent of the HK416 series, only in a semi-automatic rifle configuration developed for civilian users. The MR556A1 uses a proprietary HK short-stroke gas piston in place of the direct-gas-impingement system found on lesser AR15-style rifles that propels exhaust gas into the upper receiver to operate the action. In the "closed" HK piston system, exhaust gasses never enter the receiver, which means the HK runs cooler, cleaner and more reliably. And when adverse conditions, like dust, sand and mud are introduced, the advantage of the HK system becomes even more drastic. The MR556A1 has a cold hammer forged barrel made from cannon-grade steel, producing a barrel that ensures accuracy, even after firing thousands of rounds. Includes four 10rd magazines.

The information below comes from our Gun Caliber Dictionary and is for general reference only. It does not describe the specifications of this particular item.

The 5.56X45mm NATO cartridge was designed by James Sullivan, a member of Eugene Stoner's engineering team that developed both the M16 rifle and its original cartridge. The 5.56X45mm NATO was adopted by the U.S. military in 1964 and by NATO in 1980. With bullet diameter of .224-inch, the original M193 military cartridge used a 55-grain bullet at 3250 fps; the current M855A1 cartridge, developed by FN, uses a 62.5-grain bullet at 3020 fps, offering greater range and better penetration. The civilian version of the 5.56X45mm is 223 Remington; the cartridges are dimensionally identical but military chamber dimensions and specifications for military brass are different. It is considered safe to use 223 Remington ammo in a 5.56X45MM NATO chamber, but not a good idea to use 5.56X45mm ammo in a rifle specifically chambered for the 223 Remington. Although the stopping power of .22-caliber bullets remains controversial the 5.56X45mm has served well in now multiple generations of M16 rifles. — Craig Boddington
