CTM AAP-01/C FUKU-2 CNC UPPER SET - Short Cut-Out version V2 - Electroplated Rainbow

Turn heads and dominate high-speed CQB arenas with the CTM TAC FUKU-2 CNC Aluminium Upper Set V2 – Short Cut-Out Version (Rainbow). Custom-engineered by CTM TAC for speedsoft competitors, tournament players, and custom GBB builders, this fuku-2 skeleton upper set combines extreme weight reduction with a dazzling, multi-colour rainbow electroplated finish.

Precision CNC-machined from 6061-T6 aircraft-grade aluminium, this short skeleton chassis weighs in at an ultra-light 88 grams. As an upgraded V2 chassis, it features reinforced screw hole threads and optimized tolerances to prevent stripping or wobble under heavy cycling stress. Purpose-built as an elite aap-01 upgrade, it replaces your stock plastic chassis with rigid barrel stabilization, wider hop-up chamber compatibility (including TDC and rotary setups), and forward-mounted RMR optic placement for lightning-fast target acquisition.

Key Features

• Ultra-Light 88g Short Cut-Out Chassis: Shortened profile and aggressive cut-out windows shed maximum weight for instant target transitions and high-RPM recoil cycles.
• Dazzling Rainbow Electroplated Finish: Features a scratch-resistant, mirror-smooth rainbow electroplated coating that shifts colours under light for an unmistakable race-gun visual edge.
• Upgraded V2 Reinforced Threading: Engineered with reinforced mounting points and tight manufacturing tolerances to eliminate thread wear and screw stripping over time.
• Forward-Mounted RMR Optic Interface: Integrated forward RMR footprint provides a clear sightline and includes an RMR riser plate plus a decorative cover.
• High-Visibility Fibre Optic Iron Sights: Equipped with upgraded iron sight geometry and high-visibility green fibre optic rods for rapid sight alignment in low-light CQB fields.
• 14mm CCW Muzzle Threading: Features standard 14mm CCW (Negative) threads under the outer barrel cap for direct mounting of UV tracer units and mock suppressors.
• Universal Hop-Up Chamber Fitment: Engineered with a wider interior cavity to support Top Dead Centre (TDC), rotary, and standard hop-up units without clearance issues.

Technical Specifications

BZ Tech Team Advice:

• Threadlock Security: High-velocity gas blowback vibrations can cause small mounting screws to loosen over time. Always apply a single drop of medium-strength blue threadlocker to all RMR riser and sight mounting screws during assembly.
• Installing Fibre Optic Inserts: Pass the included green fibre optic rods through the sight channels, leaving roughly 1mm extending on each end. Gently flare the ends using the radiant heat of a lighter flame to create a clean, smooth bead that locks the fibre firmly in place.
• Ultra-Fast CQB Setup: To maximize the speed of this ultra-light 88g airsoft pistol upgrade, pair it with a CTM Tac 7075 Advanced Ultra-Light Bolt and a CTM Short Compensator S for the ultimate featherweight CQB primary.
