If you’re looking for an stripped upper for your AR-15, be sure to check out GIBBZ Sidecharge Uppers. The GIBBZ Arms G4 side charging upper receiver is a non-reciprocating upper receiver that uses most standard AR-15/M16 bolt carrier group. They are perfect for short barrel rifles (SBRs) and AR-15 pistols. We personally run them on you AR-15 in 9mm and 45ACP pistol and wouldn’t have it any other way.
