Firearm Manufacturer Brands FAQ

Why buy factory and OEM parts?
OEM parts are made to the original spec, so fit and reliability are a known quantity – ideal for restoring a gun to stock or replacing a worn part on a carry gun. Each maker page lists what is available.

Do these makers sell parts as well as guns?
Yes – most offer factory magazines, sights, barrels, grips and small parts for their firearms, and many third-party brands build upgrades for them too (see our other category pages).

Which is the oldest gunmaker here?
Beretta, founded in 1526, is the world's oldest, with Remington (1816) the oldest American maker and Mossberg the oldest family-owned U.S. gunmaker. The brand profiles dig into each one's history.
