Faxon Exclusive Enhancements

All Faxon .338 ARC rifles, pistols, and uppers feature additional milling on the upper receiver feed ramps. This proprietary modification ensures smoother, more consistent feeding of heavy ammunition like the Hornady 307-grain SUB-X, which standard M4 feed ramps struggle to handle reliably.
