Replacement barrels for Glock 34 are not created equal. L2D Combat takes pride in bringing shooters highly accurate, drop-in ready barrels for Glock that can take the abuse of real-world use and remain true shot after shot. The L2D Combat Glock 34 threaded barrel is a great choice for those of you who are ready to make Glock 34 upgrades and prefer a threaded barrel muzzle.

Open the Box...And Smile

When the L2D Combat Glock 34 threaded barrel comes out of the box, you’ll know you have something special. Other manufacturers just don’t make their barrels like L2D Combat Glock 34 threaded barrel. While other Glock 34 upgrades can fall under a “your mileage may vary” heading, you know this one is going to be good from the moment you see the husky chamber body. It’s designed to provide complete support when equipped. The stability gained there isn’t sacrificed further on either. L2D’s Glock 34 upgrades include a full-length fluted barrel that handles easily because it’s lighter, yet stays strong and won’t distort even under the heat of repeated firing. A light and a good look down the barrel reveals precision cut rifling that will do a far better job of keeping your bullet stable on its way to the target than those finished with lesser rifling methods. The L2D Combat Glock threaded barrel culminates in a crowned muzzle for an added touch of stability. These threaded barrels also include thread protectors to keep those threads clean and true when there isn’t a muzzle device equipped.
