Ultra-Rare Left-Hand Threaded Glock Barrels

Threaded barrels are commonly used to mount suppressors or compensators. Most barrels in the U.S. use right-hand threads, which can cause suppressors to loosen during use due to the direction of the bullet’s spin. This barrel solves that problem by using reverse (left-hand) threads, which naturally tighten the suppressor as you shoot. Just be sure you have the compatible hub that takes a 13.5x1 Left Hand thread pitch.
