Dominate high-speed CQB matches and make an unforgettable statement on the field with the CTM TAC FUKU-2 CNC Aluminium Upper Set V2 – Short Cutout Version (Diamond Gold). Custom-engineered by CTM TAC for speedsoft competitors, tournament players, and custom GBB builders, this fuku-2 skeleton upper set pairs extreme weight reduction with a high-lustre, electroplated Diamond Gold finish.
Precision CNC-machined from 6061-T6 aircraft-grade aluminium, this short skeleton chassis features aggressive cutout windows that shed unnecessary front-end mass for snappier recoil cycles and effortless target transitions. As an upgraded V2 chassis, it introduces reinforced rear sight screw hole architecture and optimized manufacturing tolerances to eliminate thread wear and screw stripping under continuous high-RPM firing. Purpose-built as a top-tier 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.
Shortened length combined with skeletonized cutouts dramatically reduces front-end weight for high-speed room clearance and instant target tracking.
Features a scratch-resistant, mirror-smooth electroplated gold coating that stands out under field lights while providing long-lasting corrosion protection.
Milled with reinforced rear sight mounting points and tight tolerances to prevent thread stripping or wobble over time.
Integrated forward-mounted RMR footprint brings your dot sight closer to your eye line for faster sight acquisition and target transitions.
Equipped with matching electroplated iron sights and high-visibility green fibre optic rods for rapid target acquisition in low-light indoor arenas.
Features standard 14mm CCW (Negative) threads under the outer barrel cap for direct installation of UV tracer units and mock suppressors.
Engineered with a wider interior cavity to support Top Dead Centre (TDC), rotary, and standard hop-up units without clearance issues.
