Parts made by people who shoot

Combat Armory cuts barrels, slides and small parts on its own machines in the United States. The same tolerances that go into a match barrel go into a $1 magazine release spring, because the part that fails is always the cheap one nobody thought about.

Everything here fits factory-specification firearms without hand-fitting: Glock Gen 1–5 barrels and slides, AR-15, AR-10 and AR-9 uppers and internals, SIG and Smith & Wesson barrels, and drop-in triggers. If a part needs fitting, the listing says so.

Common questions

How fast does Combat Armory ship?

Orders ship within 24 hours. Anything placed over the weekend goes out on Monday. Free shipping applies to orders over $99.00.

Are Combat Armory barrels drop-in?

Combat Armory match-grade barrels are made to factory Glock specification and drop into a factory slide without fitting. Threaded barrels use standard 1/2x28 (9mm and .357 SIG) or .578x28 (.40 and .45) threads.

Do you sell complete firearms?

We sell stripped and complete lowers, uppers, barrels, slides and internal parts. Anything serialised ships to a licensed FFL for transfer.

Can these parts ship to my state?

Most parts ship nationwide, but some items are restricted in certain states. It is the buyer’s responsibility to know and obey federal, state and local law before ordering.

What is the return policy?

Unused parts in their original packaging can be returned within 30 days. Barrels and slides that have been fired, fitted or refinished are not returnable.
