CTM TAC FUKU-2 Skeletonized Two-Tone CNC Upper Receiver Kit – AAP-01

The CTM TAC FUKU-2 Skeletonized Two-Tone Upper Receiver Kit is a high-performance upgrade for the Action Army AAP-01 and AAP-01C gas blowback pistols. Precision-machined from lightweight 6061 aluminum, this version introduces a more aggressive skeletonized cut to shed weight and increase cycling speed while adding bold two-tone anodized finishes. With a forward-mounted RMR footprint, improved iron sights, and reinforced screw hole design, the Skeletonized FUKU-2 provides enhanced performance, reliability, and unique styling that makes your AAP-01 stand out both on the field and at the bench.

Key Features

Ultra-Lightweight Skeletonized Build: At just 130g, this upper is nearly 35% lighter than the standard FUKU-2, delivering faster cycle rates, snappier recoil response, and improved handling in fast-paced games.

Forward-Mounted Optics & Sights: Integrated RMR footprint allows direct red dot mounting, while the included riser plate expands compatibility. Redesigned front and rear sights with fiber optic inserts provide a clearer, more accurate sight picture.

Reinforced & Reliable: V2 screw hole reinforcements and tighter tolerances ensure durability under stress, preventing the loosening or stripping issues found in weaker aftermarket uppers.

Two-Tone Custom Styling: Available in striking anodized color combinations such as Black/Red, Silver/Grey, Green/Silver, Blue/Silver, Gold/Gold, and more, the Skeletonized kit brings unmatched visual customization to your AAP-01 build.

Full Performance Compatibility: Designed to accept TDC, rotary, and standard hop-up units, while retaining cross-compatibility with FUKU-2 and FUKU-2 Skeleton outer barrels (“buckets”). A built-in under-barrel Picatinny rail and 14mm CCW threaded muzzle provide full accessory and tracer/suppressor options.
