New Production US manufactured high quality MICRO UZI barrels for both MICRO sub-machinegun as well as MICRO semiauto pistol. Barrels are correctly machined for a drop-in replacement fit and are threaded 1/2-28 TPI for suppressor use (not ported). They are for MICRO size UZI receivers only and will NOT fit a full size UZI carbine or Mini UZI receivers (which are also available).
The barrels are made from 4140 chrome moly steel, button rifled, 1:10 twist and are military black phosphate finished with OAL 5-1/4". The chambers are machined identically to the original SMG military profile for reliable feeding and chambering.
