Engineering:List of AR platform calibers

From HandWiki

The AR platform has become widely popular for makers of military and sporting rifles. Although the designations "AR-10" and "AR-15" are respectively trademarks of ArmaLite and Colt, variants of both are made by many manufacturers. The rifle comes in 2 calibers, the military caliber of 5.56 X 45 or the equivalent .223. Because of the pressures associated with the 5.56mm, it is inadvisable to fire 5.56mm in an AR-15 marked .223 and can result in damage to the rifle or injury to the shooter. The AR-15 can be converted to other calibers; it is then referred to as an AR-15 Style Rifle.
