CTM AAP-01/C FUKU-2 CNC UPPER - Baby Shark Cutout - Army Green

CTM Tac AAP-01 FUKU-2 CNC Upper – Baby Shark Cutout Version - Army Green

The Baby Shark upper already turned heads, and the Cutout version takes it further, stripping weight without stripping away any of that aggressive shark-inspired styling. This is a full replacement upper for the AAP-01 and AAP-01C, built around the same shark-series design language, now with extensive precision cutouts that shave grams while sharpening the whole silhouette.

CNC-machined from 6061 aluminium, this FUKU-2 upper doesn't sacrifice performance to hit that lighter weight. Even at a lighter weight, it's still a serious airsoft pistol upgrade, just built to feel quicker in the hand and look even more aggressive on the field.

Why the Cutout Version Stands Out

• Aggressive Baby Shark Cutout Aesthetics: Features precision-milled weight-reduction cutouts along the outer receiver frame, giving your airsoft pistol upgrade a futuristic race-gun look while shedding every extra gram.
• Precision 6061-T6 CNC Aluminium Build: Milled from high-tensile aircraft aluminium alloy to guarantee rock-solid structural integrity and flawless barrel stabilization during high-RPM full-auto strings.
• Enhanced Front-End Responsiveness: The skeletonized cutout version shaves significant weight off the front of your sidearm, enabling instantaneous target transitions and reduced wrist fatigue in tight CQB quarters.
• Direct Optic & Riser Plate Support: Includes a dedicated micro red dot/RMR optic mount and riser plate that bolts directly onto the upper receiver frame for an unwavering, ultra-flat sightline.
• 14mm CCW Tracer Adapter Included: Equipped with integrated 11mm CW inner barrel threads and comes packaged with a 14mm CCW thread adapter for seamless installation of your favourite UV tracer units and mock suppressors.
• Drop-In AAP-01 & AAP-01C Fitment: Milled to exact tolerances for seamless integration with standard Action Army AAP-01 and AAP-01C lower receiver assemblies.

Technical Specifications

BZ Tech Team Advice:

• Highlight Your Inner Barrel: Because the cutout version features open window cuts along the chassis, pairing this upper with a coloured or polished stainless steel inner barrel creates a striking visual contrast that shows through the receiver.
• Inner Barrel Length: Match this compact baby shark receiver with a 129mm to 138mm precision inner barrel to keep the muzzle sitting flush inside your 14mm CCW thread adapter for optimal BB trajectory and tracer ignition.
• High-Speed Engine Pairing: To maximize the cycling efficiency of your fuku-2 build, pair this pistol upgrade with a CTM Tac 7075 Advanced Bolt Lite and an upgraded 160%–200% recoil spring. This combination creates an indestructible, high-RPM firing engine for your airsoft pistol.
