Heckler and Koch MR556 A1 Competition Model Semi-Automatic Rifle 223 Remington/5.56 NATO 16.5" Barrel With Muzzlebrake 30 Round Capacity Black

Using the HK MR556A1 and input from many competitive shooters, the Competition model was developed for both casual shooters and the most demanding competitor. It retains many standard features of the MR556A1, including a German-made long service barrel produced by HK's famous cold hammer forging, and HK's piston operating system which uses a gas piston and pusher rod to improve reliability and reduce cleaning/maintenance. Ideal for 3-gun matches, the Competition Model is optic-ready, and includes a free-floating, 14" Modular Rail System (MRS) handguard which is lightweight and easy to customize while presenting a more ergonomic, comfortable handguard surface compared to rectangular full rail systems. The extended magazine release allows for quick magazine changes, and an innovative compensator by Operator Suppressor Systems Inc. (OSS) replaces the standard MR flash hider. The Magpul CTR (Compact/Type Restricted) buttstock is easy to adjust, with a profile and weight ideal for competitive shooters. This Competition model includes one 30-round magazine.

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
