Stripped Uppers

Completing an AR build with a stripped upper gives you the greatest degree of flexibility, as you can choose the bolt carrier group, barrel, gas system, and other upper parts and components you want to incorporate into the build. Explore the GIBBZ Arms collection of non-reciprocating side-charging stripped AR uppers, which includes the 9mm G9 upper, perfect for building a pistol-caliber carbine (PCC), as well as the G4 upper, which sports an enlarged ejection port that is compatible with all common AR calibers from .22LR to .50 Beowulf. Contact us if you have any questions about the specifics of any of our AR uppers.
