The Colt AR-15A3 is an exceptional patrol rifle with tactical accuracy chosen by many federal, state, and local agencies. The 16.1 inch heavy barrel with a 1:9 inch rifling twist allows flexibility in ammunition selection from 45 grains all the way up to 69 grains. The telescopic M4 stock adjusts to four positions to enhance mobility and fit to a wider range of operators. The Magpul MBUS rear sight is the ultimate back up iron site. The flat top upper receiver allows for easy mounting of optical, night vision and other tactical sighting systems. The tactical carbine is the answer to all the requirements of modern law enforcement, defensive use or all around carbine. It includes a 30 round PMAG 30 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
