CTM Tactical FUKU-2 CNC Upper Skeleton for AAP-01 Grey / Black




The CTM Tactical FUKU-2 CNC Upper Skeleton for AAP-01 Grey / Black is an updated, lighter and structurally reinforced upper for the AAP-01. This Skeleton version combines a modern open design with a subtle grey/black colour scheme, ideal for those looking to create a custom build with a technical look and a professional finish.
Materials and fastenings
This upper is fully CNC-machined from high-quality aluminium and designed with a focus on weight reduction and increased strength. The updated construction results in a lighter yet stiffer structure than previous generations.
The screw holes have been reinforced and redesigned to provide greater structural strength and tighter tolerances. This ensures a secure assembly and a stable structure, even under heavy use.
The rear sight has been redesigned to ensure a better fit. The forward-mounted RMR, combined with improved iron sights, provides a clearer and more accurate sight picture.
The set is cross-compatible with outer barrels ranging from the original FUKU-2 to the FUKU-2 Skeleton version.
Usage and compatibility
The CTM Tactical FUKU-2 CNC Upper Skeleton for AAP-01 Grey / Black is designed for maximum compatibility and flexibility. Its wider hop-up compatibility allows for the use of TDC, Rotary and standard hop-up units.
The included CNC RMR riser provides extra flexibility for mounting various red dot sights. The upper is fully compatible with the AAP-01 platform and designed to replace the standard upper directly.
The combination of weight reduction and reinforced construction makes this version suitable for both performance builds and aesthetic custom projects.
