Action Army AAP-01 Replacement Part 21 - Upper Receiver ( Black )

Genuine Action Army replacement upper receiver (part 21), black for the Action Army AAP-01 gas blowback pistol.

The complete upper receiver in black. A substantial spare, normally bought after a crack or to change the colour of a build.

Fitment: Action Army AAP-01 and AAP-01C. Most AAP-01 parts are shared across the two, but not all — check the part number against your parts diagram before ordering.

Taken from new disassembled pistols, so parts may carry small marks or minor defects but are unused. Supplied in plain packaging.
