AR-15 Carbine Gas Barrels

364 products · page 1 of 13

A carbine gas system puts the gas port about 7 inches from the receiver. It suits barrels from about 10 to 16 inches, including the classic 14.5 and 16-inch M4-style barrels, and cycles a wide range of ammo. Use a carbine gas tube, and a handguard that reaches past the gas block.
