CTM AAP-01/C FUKU-2 CNC UPPER - Skeleton - Electroplated Gold

CTM Tac AAP-01/C FUKU-2 CNC Upper - Skeleton - Electroplated Gold

Nearly 35% lighter than a standard FUKU-2 upper, the Skeleton design is one of CTM Tac's most respected engineering upgrades for the AAP-01. This electroplated version wraps that performance in a genuinely show-stopping finish. If you want your airsoft pistol to cycle faster and turn heads, this is the upper that does both.

Precision CNC-machined from 6061 aluminium, the skeletonised cuts strip weight without cutting corners on strength. CTM Tac reinforced the screw holes specifically to hold up to the demands of a lighter build, so you get snappier cycling and sharper recoil response without sacrificing durability. Finished in a mirror-bright Electroplated Gold or shifting Electroplated Rainbow coating, it's a genuine centrepiece upgrade for a serious AAP-01 upgrade build.

Why You NEED the Skeleton Upper

• Ultra-Light 130g Skeleton Chassis: Precision cutouts shed overall mass to increase cycle speed, reduce wrist fatigue, and enable lightning-fast target transitions.
• High-Lustre Electroplated Coating: Features a scratch-resistant electroplated metallic plating that adds a custom aesthetic to your airsoft pistol.
• Reinforced V2 Screw Hole Architecture: Built with reinforced screw mounting points and tight manufacturing tolerances to eliminate thread wear and wobbling.
• Forward-Mounted RMR Optic Interface: Positioned forward on the receiver for cleaner eye relief, including an RMR riser plate and decorative cover.
• Fibre Optic Iron Sights Included: Features redesigned front and rear sights paired with high-visibility green fibre optic inserts for rapid sight alignment.
• 14mm CCW Tracer Threading: Outer barrel bucket features a standard 14mm CCW male thread with a CNC thread cap for instant UV tracer unit mounting.
• Universal Hop-Up Compatibility: Accommodates standard, rotary, and Top Dead Centre (TDC) hop-up chambers without clearance issues.

Technical Specifications

BZ Tech Team Advice:

• Threadlock is Crucial: Gas blowback vibrations can cause small metal screws to back out during intense play. Always apply a tiny drop of medium-strength blue threadlocker to all RMR riser and sight mounting screws during assembly.
• Melting Fiber Optic Rods: Insert the included green fibre optic rods into the iron sight channels, leaving roughly 1mm protruding on each end. Gently singe the ends with a lighter flame to create a smooth, flared bead that locks the fibre firmly into place.
• High-Speed Bolt Pairing: To get the most out of this 130g airsoft pistol upgrade, pair it with a CTM Tac 7075 Advanced Bolt Lite and an upgraded 160%–200% recoil spring for an ultra-fast cycling platform.
