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.
