The Faxon Arak-21 Complete Upper in 7.62x39 with a 12.5" barrel is a ready-to-run upper receiver assembly built around the AK-pattern platform. If you're building a short-barreled rifle (SBR) or upgrading an existing Arak-21 platform build, this complete upper gives you a finished, headspaced assembly that pairs the proven intermediate cartridge with Faxon's barrel quality and a compact profile suited to close-quarters shooting, hunting in dense timber, or home defense scenarios where maneuverability matters.

Faxon has earned respect in the AR and AK communities for barrel craftsmanship and attention to detail. The 12.5" barrel strikes a balance between velocity and shootability—short enough to handle quickly, long enough to generate useful energy in 7.62x39. As a complete upper, you're getting a matched, ready-to-run assembly: no guesswork on headspace or part compatibility. Just mount it to your receiver or complete lower, and you're in business.

Whether you're a 7.62x39 shooter who wants a compact, maneuverable setup or you're expanding an Arak-21 collection with a shorter barrel option, this upper arrives properly assembled and tested. It's the kind of straightforward, no-nonsense component that appeals to builders and shooters who value reliability and fit over hype.
