STEN MK2 9mm New Production US manufactured high quality STEN SMG barrels. Available in traditional non-threaded muzzle or professionally CNC threaded 1/2-28 TPI on centers for easy screw-on suppressor or muzzle accessory mounting.
The barrels are made from 4150 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.
Unlike many other newly manufactured barrels for sale from other sellers, our barrels are hand polished (rather than rough finished right off the machine) and are bead blasted for a uniform matte finish before being black phosphate finished (rather than "in the white" for you to have to finish it). Our barrels are finished and ready to install in your STEN.
This barrel is USA made and is 922(r) compliant in accordance with ATFE rules and regulations. Please contact your local ATF office for additional regulatory information should you have any questions.
