TMC Government Match Drop-In Barrel Bushing – Blued
The TMC National Match Drop-In barrel bushing has an outside diamater of .700-.701 and an inside diamater of .581-.582. Disigned to be used with replacement barrels such as the Kart, Wilson KKM, Barstow and Nowlin barrels. We have tested this bushing with a Kart barrel and the bushing to barrel fit was as good as a custom fitted oversize NM bushing. Made from ordnance carbon steel for long life and wear resistance. Requires gunsmith fitting.
