New Production US manufactured high quality UZI 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 barrel is professionally CNC threaded 1/2-28 TPI on centers for easy screw-on suppressor or muzzle accessory mounting.
The barrels are 10.25" and 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.
