AR PLATFORM

Defining what is a standard caliber for either ArmaLite Model 15 (AR-15) or Model 10 (AR-10) platform is at its best a impossible task. AR’s define a modern rifle platform that is adaptable and versatile. AR-10’s are centered around a .308 case so there is many caliber variants not listed in the AR RIFLE BRASS MENU so shopping our main RIFLE BRASS MENU will list a larger variety. AR-15 can be chambered in a multiple of calibers, the one defining factor is a overall case length that will fit in a magazine, this is 2.26 inches or less.
