Action Army AAP01 Black Mamba Upper, B lader ESD Rocket Valve for GBBThis cool Action Army Black Mamba upper receiver is a cool drop in upgrade that gives you a whole new design on the AAP01 pistol. You get picatinny rails both on top and bottom to attach different accessories. The built in iron sights are also slightly raised for better eye tracking. The B kit comes with a "clean" upper without stippling etc. The entire upper is cut with a CNC machine and has a black finish.
