New Production US manufactured high quality UZI SMG barrels. Barrels are correctly machined to fit original UZI SMG full size receivers with the SMG trunion diameters and with NO barrel restricting ring. These SMG barrels will NOT fit a semi-auto even if it has been converted to a machine gun since the trunion diameters are not the same. Barrels for semi-auto receivers (whether still a semi or converted to a machine gun) are also available.
The barrels are made from 4140 chrome moly steel, button rifled, 1:10 twist and are military black phosphate finished . The chambers are machined identically to the original SMG military profile for reliable feeding and chambering . The length is 10.25".
THIS BARREL WILL NOT FIT IN A SEMI-AUTO CARBINE RECEIVER, EVEN IF THE RECEIVER HAS BEEN CONVERTED TO A MACHINE GUN. This barrel is only for factory original machine guns and firearms built using machine gun parts kits.
