The AR-10A family of Armalite rifles is functionally identical to the AR-10B family. Operation, controls, and maintenance are the same, however the AR-10A family is designed to accept early Armalite AR-10 "Waffle" magazines and other magazines copied from them. The AR-10B family still accepts the proprietary steel magazines. Neither family of rifles will function correctly with the other alternate magazine. Like its rifle-length brother, the AR-10A SuperSASS Carbine accepts third party polymer magazines. It is a lighter weight, versatile and supremely accurate firearm perfect in law enforcement and military support roles. Used in its suppressed mode, the SASS Carbine can help facilitate communication between team members.
