The AR-15 was developed as a lighter, 5.56 mm version of the AR-10. The AR in all ArmaLite pattern firearms simply stands for ArmaLite, and can be found on most of the company's firearms: AR-5, a .22 caliber rifle; the AR-7, another .22 caliber; the AR-17 shotgun; the AR-10 rifle; and the AR-24 pistol.
All modern cartridges of these calibers are basically ACP. Lets pick on the the .45 ACP, when you buy a box of .45 ACP they could be made by any of two dozen different makers, but the name is the same, .45 ACPs or .45 Automatic Colt Pistol cartridges. They could be full metal jacket, hollow nose or what ever, still .45 ACP cartridges.
