Faxon Firearms Enhanced Forged 338 ARC Stripped Upper Receivers, With Completion Kit, Black, UR-FAX-F-A-C-338
Faxon's Enhanced Forged .338 ARC stripped upper receiver is a forged 7075-T6 AR-15 upper marked for .338 ARC. It arrives without a barrel, bolt carrier group, or small parts.
Pair it with a Faxon .338 ARC barrel and the Type 2 .136 bolt offered on that barrel's product page. Verify headspace after assembly, then use the magazine specified for the completed upper and lower host.
This receiver is the foundation, not a complete host. The barrel, BCG, handguard, forward assist, ejection-port cover, lower, and magazine remain separate choices.
