Full-upgrade internal pack for AEG airsoft guns

These packs offered by the OPS-store workshop will enable you to completely upgrade the internals of your AEG airsoft replica with quality parts. You can choose between a High Speed pack (300 FPS - 350 FPS) or a High Torque pack (350 FPS - 400 FPS - 450 FPS) if you're looking for a higher rate of fire or more power. Assembly and testing of the replica are handled by our technician.
