CTM Tactical FUKU-2 CNC Upper Set Long Cut Out for AAP-01 Grey / Black

The CTM Tactical AAP-01 FUKU-2 CNC Upper Set Long Cut-Out Grey Black is designed for players who want to upgrade their AAP-01 to a more stable, faster and more versatile platform. Whilst standard uppers often become the limiting factor in advanced builds, this long CNC upper offers immediate gains in cycle speed, control and expansion options. Particularly with longer configurations, you’ll notice that your setup performs more smoothly and consistently.
Usage scenarios
This upper really comes into its own in builds where performance is key. In CQB, you’ll benefit from faster cycling and immediate response, which is essential during rapid engagements and follow-up shots. For outdoor and milsim applications, the extra length offers greater stability and control, particularly when combined with longer inner barrels or suppressor setups.
Many players use this upper to convert their AAP-01 into a primary platform. Think of combinations with carbine kits, optics and HPA systems, where stability and consistent performance are crucial.
Materials and techniques
The upper is CNC-machined from high-quality 6061 aluminium, ensuring a strong yet lightweight construction. The long cut-out design reduces unnecessary mass, allowing the bolt to move faster and the cycle to run more efficiently. This results in noticeably faster and smoother operation.
The longer frame also provides additional rigidity, which is important for precision builds. The V2 upgrade, featuring improved rear sight screw holes, prevents issues such as loosening or wear during intensive use. The set comes complete with CNC sights, a decorative inner body, fibre optics and all necessary mounting hardware.
Practical experience
In practice, we find that players who switch to a longer upper often notice an immediate difference in balance and control. Many players experience inconsistency when they upgrade their AAP-01 with longer barrels, but without a modified upper, stability suffers.
With this FUKU-2 upper, that problem disappears. Particularly during rapid semi-automatic fire, the cycling remains consistent and the recoil feels more manageable. When used outdoors, you’ll notice that the extra length helps to stabilise your aim, resulting in better grouping at medium range.
Who it is / isn't suitable for
This upper is ideal for players looking to seriously upgrade their AAP-01 and achieve maximum performance. CQB players benefit from its speed, whilst outdoor and milsim players benefit from its stability and precision. It also serves as an excellent foundation for tech-oriented builds and custom projects.
For players who want to keep their AAP-01 completely stock or have no plans for further upgrades, this upper is less relevant. Its added value lies mainly in combination with other performance upgrades.
