Armalite's M153GN is the flagship competition rifle built to win. This rifle is compact, light, and ultra-fast. The low profile handguard, with a railed front sight base, covers a free-floating stainless steel barrel with ArmaLite's own tunable muzzle brake. An adjustable gas block also allows the rifle to be individually set for optimal performance. It has an MBA-1 lightweight precision stock (adjustable LOP/comb height), Timney single-stage trigger, and Raptor ambidextrous charging handle. This carbine model has a 13.5" barrel pinned and welded to muzzle brake to create a 16" barrel and a carbine-length gas system beneath a 12" free-float 3-gun handguard. It is CO compliant and includes a 10-round magazine.

Caliber Dictionary
The Below Information Has Been Provided From Our Gun Caliber Dictionary And Is Meant For Informational Purposes Only. It Is Not Intended to Describe The Unique Specifications For This Ammunition.
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
