Complete Uppers

Explore Gibbz Arms’ collection of complete uppers, which are ready to mate to a lower (compatible with mil-spec and most other lowers), streamlining the process of building a custom rifle at home. These side-charging uppers come complete with a handguard, an integral Picatinny rail machined from the receiver stock, and Gibbz Arms’ patented, non-reciprocating side-charging handles. They’re also designed with a bolt carrier door that facilities BCG removal and also helps mitigate gas release during operation.
