Pistol-caliber carbines are some of the most popular options on the market right now, and the versatility of AR-style PCCs make for an attractive build option for today's firearm tinkerers. Faxon Firearms is getting in the game with a complete, ready-to-shoot upper receiver that'll finish off your 9mm carbine build. Each Faxon Firearms AR-15 Complete Upper Receiver is constructed on the company's Enhanced Forged Upper Receiver, which is paired with the company's 10.5-inch or 16-inch Taper 9mm barrel. The uppers are compatible with both Colt and Glock®magazine lowers, and the unit is compatible with today's popular binary triggers as well. Other features of the Faxon Firearms AR-15 Complete Upper Receiver includes a Faxon Aluminum Handguard, available in either 9-inch or 15-inch lengths, depending on barrel length selected, as well as an A2-style flash hider. The uppers also come equipped with the company's Gen 2 9mm bolt-carrier group.
