Description
Originally built as a spare, but this upper turned out to be a surprisingly solid performer. Tuned for consistency, power, and heavy BB use.
Build Details:
- AAP-01 upper receiver with 5KU lightweight bolt
- Stock nozzle + TTI piston head (reliable feeding & strong air seal)
- 300% nozzle spring & 150% recoil spring (ensures bolt locks and cycles properly)
- Action Army 132mm 6.03mm precision inner barrel
- TTI TDC mod for precise hop adjustment
- Quantum bucking – lifts anything up to 0.45g BBs with ease
Performance:
- Tuned for 1.5–1.7J, keeping it site-legal across the UK (within DMR limits)
- Optimized for 0.40g BBs (perfect balance of speed & punch), but happily runs 0.45g
- Consistent cycling with the lightweight bolt setup
Extras:
- Includes Action Army carbine kit for stability and proper shooting stance
- You’ll need a lower, but tested and confirmed working with both Shinobi and standard AAP lowers
This upper is dialed in and ready to go — just drop it on your lower and you’ve got a reliable, hard-hitting AAP build.
