Give your Action Army AAP-01 the ultimate competitive upgrade with the CTM AAP-01 FUKU-2 CNC Upper "Shark". The FUKU-2 swaps out your stock polymer receiver for an aircraft-grade aluminium chassis, giving you the competitive edge on your opponents and turning the appearance of your standard AAP-01 into something more aggressive.
CTM has designed the FUKU-2 with shark-gill skeletonised cutouts to reduce slide weight for lightning-fast blowback cycling, crisp trigger response, and maximum gas efficiency.
Key Features
Aggressive "Shark" Skeletonised Cutouts: The shark-gill cutouts drop a massive weight of the upper to allow your bolt to cycle significantly faster for rapid-fire springs.
Precision CNC Aluminium Build: Milled from solid aircraft-grade 6061 aluminium alloy to eliminate receiver flex and provide rock-solid alignment for your inner barrel and hop-up.
Modular Picatinny Rail System: Includes detachable top and bottom 20mm RIS rails for mounting micro red dot optics, tactical flashlights, or laser aiming modules.
Integrated Sight & Thread System: Comes equipped with high-visibility fibre optic front and rear sights for instant target indexing, plus standard 14mm outer barrel threads for suppressors and tracer units.

BZ Tech Team Advice:
Maxing out Cycle Speed: Pair this lightweight FUKU-2 upper with a CTM TAC Advanced Lightweight Bolt and a 150% or 200% recoil spring. The combination of reduced reciprocating mass and stiffer spring tension creates an insanely fast, flat-shooting machine-pistol cycle.
Non-Permanent Threadlock: Because CNC aluminium transfers vibrations differently than polymer, apply a single drop of blue threadlocker to your rail and sight mounting screws during assembly to keep everything tight through heavy gameplay.
Hop-Up Unit Fitment: Fits standard stock AAP-01 hop-up chambers as well as upgraded CNC rotary units (like the CTM or Action Army CNC chambers). Take your time aligning the hop-up unit screw holes to guarantee flawless BB feeding into the nozzle.
