CTM FUKU-2 Skeleton CNC Upper Set for AAP-01 - Green / Silver

FUKU-2 Skeleton Upper Set for AAP-01 / AAP-01C

Looking for a lightweight upper with an aggressive design that gives your AAP-01 pistol a completely new character? Do you want faster and easier handling thanks to reduced weight while maintaining the strength of CNC-machined 6061 aluminum? Do you need an upper that is ready for TDC hop-up chambers, has a mounting plate for red dots, and includes threading for tracer suppressors? Then the FUKU-2 Skeleton Upper Set is exactly what you need. This upgraded version of the FUKU-2 upper is 45 g lighter due to its precision-cut weight-reduction windows. The upper includes a top mounting footprint plate for red dots, a short lower RIS rail for grips or lights, a standard 14mm CCW thread with a CNC protector, and a full set of fiber-optic sights. It is also compatible with compensators from previous FUKU-2 versions. As a bonus, it fully supports precision hop-up chambers with TDC adjustment. With a total weight of only 130 g, it adds speed and responsiveness without sacrificing durability – enhanced mounting points and stressed areas ensure long service life. If you want to turn your AAP pistol into a true masterpiece, combine this upper with more CTM external parts and, of course, complete it with the best internal upgrades. The rest is up to your imagination.
