Rosco Mfg. 9mm Barrels
Rosco Manufacturing has added 9mm options to its line of Bloodline AR platform barrels. The 9mm barrels are available in 5.5-, 7.5- and 14.5-inch lengths. The barrels are a compliment to the newly opened Pistol Caliber Carbine division of the USPSA with an ideal length-to-weight ratio. The barrels also feature a 1:10-inch twist to help support heavier defense and subsonic loads.
