Combat Armory Glock Barrels & AR-15 Parts

Combat Armory machines match-grade Glock barrels, slides, AR-15 components and pistol small parts in the USA, and American Guns & Ammo stocks the full line with nationwide shipping. Their reputation was built on drop-in Glock barrels — 416 stainless, heat treated to RC 41, conventional rifling that runs lead and coated bullets factory polygonal barrels warn against.

What we carry

Start with the deep selection of Glock barrels in standard and threaded profiles and a full range of finishes, plus matching thread protectors. On the pistol side there are assembled Glock slides and every Glock small part — strikers, extractor plungers, connectors and pins. AR-15 builders will find lowers, upper assembly kits, handguards and complete lower parts kits.

Newest platform: Ruger RXM

Combat Armory was early to machine dedicated Ruger RXM barrels, bringing the same match-grade formula to Ruger's Glock-compatible 9mm.

How it ships

Combat Armory parts and barrels ship directly to you; complete firearms and serialized lowers transfer through a licensed FFL dealer. Read our in-depth guides in the journal before you build.
