SKELETON Construction (Lightness and Extreme Resistance):
Do you want an Upper Receiver with an aggressive design that gives your AAP-01 a unique character? The "Skeleton" version of the famous FUKU-2 has been redesigned for the most demanding players. Thanks to lightening windows cut with surgical precision, this set weighs 45 grams less than the previous Cutout version, stopping the scale at just 130 grams. The result? Unprecedented handling, while maintaining the absolute robustness of the 6061 aeronautical aluminum body CNC machined, with reinforced screw holes for millimeter tolerances on the Lower.
Ready for Advanced Aiming and Tracers:
CTM TAC has not overlooked any tactical details. The kit includes a raised plate (RMR Riser) mounted in an advanced position, for faster and cleaner red dot acquisition. If you prefer metal sights, you will find redesigned front and rear sights with green fiber optic inserts included. Obviously, the front boasts a standard 14mm Counter-Clockwise (CCW) thread with its CNC thread cover, essential for mounting silencers or tracer units for night games or CQB arenas.
The Importance of Threadlocker: This kit is entirely made of metal and is assembled with several small steel screws. GBB pistols generate a lot of vibration. When assembling the Upper, the RMR base and the sights, put a micro-drop of blue (medium) threadlocker on each small screw. It will save you from losing precious pieces in the middle of a tournament!
How to fix the Optical Fiber: The green fiber optic bars arrive straight. To install them correctly, insert them into the holes in the sights, leaving about 1 millimeter protruding on each side. Then, bring the flame of a lighter *very gently* to the ends: the plastic will melt, forming a small "ball" that will lock the fiber firmly in place, creating at the same time a wide and bright aiming point.
Take advantage of the TDC: This Upper has been internally excavated to comfortably accommodate TDC Hop-Up chambers. If you are doing an upgrade of this level, don't stop at aesthetics: combine it with a TDC Hop-Up unit to have laser shooting precision!
