PIKE ARMS® M11/9 BARREL THREADED 3/4x10 TPI
- FOR SMG OR PISTOL
These Pike Arms® new production US manufactured high quality M11/9 barrels for machine guns or semi auto pistols are professionally threaded 3/4 x 10 TPI identically to the original SWD machine gun barrels for MAC style suppressor or muzzle accessory mounting.
The barrels are precision CNC machined between centers for accurate thread alignment from 4150 chromemoly steel, button rifled and are hot salt blued or parkerized for a durable factory finish.
The chambers are machined to match the original SMG profile for reliable feeding and chambering. If your SMG barrel has a high round count, a spare barrel is always a good option to have on-hand.
