Reproduction Sterling Barrels
 
All of our barrels are made from exclusively from new, Green Mountain barrel blanks, an American company known for their excellent quality and accuracy. The outside diameter configuration is CNC turned and milled to exacting tolerances. The chambering is accomplished individually on a manual lathe to assure a perfect fit for the cartridge it is designed for.

Sterling Mk4 Barrels, Model SB01

These new, reproduction Sterling Mk4 barrels are CNC turned from Green Mountain, chrome moly blanks and have a bead blasted, black oxide finish. They were designed from an original Sterling barrel and held to exacting tolerances. A fine replacement for your aging SMG barrel or a high quality, U.S. made part if you are building a Sterling pistol from a parts kit.

Sterling Mk7 Barrels
  • 8" Model SB02
  • 6" Model SB03
  • 4" Model SB04
  • All have 1/2-28 end threads

The 1/2-28 thread at the muzzle is not standard on an original Sterling barrel but we added it for people who wish to attach a flash hider or suppressor.



The flash hider shown on the left is our aluminum, KP02, 4" slip over model. The one on the right is a standard steel AR-15 A1 birdcage flash hider that has been modified for the 9mm caliber.

Please note that when using an AR-15 or any other flash hider designed for a .223 (5.56 NATO), it will have to be modified to add clearance for the larger 9mm projectile. Failure to do this will certainly damage the barrel and the weapon but more importantly, it could have lethal consequences for the shooter and anyone in the vicinity! Always check the bore of any accessory you screw onto the end of your barrel to make sure it has the required clearance.
