The HPA Revolution for CQB:
Do you love the ultra-light setup with your AAP-01 or your Glock, but are you tired of running out of the magazine's 20 BBs in two seconds? The CTM TAC adapter transforms your sidearm into an unstoppable primary weapon. By converting to a High-Pressure Air (HPA) system and using single-stack magazines for M4 rifles (up to 250 rounds), you'll have unlimited firepower and consistent performance in any climate condition.
90 Degree Design and "Zero BB Drop":
Unlike classic straight adapters that make the pistol clunky and impossible to use while prone, this 90° model aligns the magazine parallel to the arm. This ultra-low profile allows you to shoot from extreme angles and very low barricades. Furthermore, CTM TAC has incorporated a clever internal retention system: when you remove the empty M4 magazine for reloading, the duct will not drop a single BB on the ground!
THE DONOR SHELL (Not included!): This adapter is not "Plug & Play" straight out of the box. To install it, you must sacrifice one of your gas magazines (preferably the original Action Army one). You will need to disassemble the base of the gas magazine, remove the spring, and screw this CTM polymer block directly under the metal shell using the long screw provided.
Attention to Glocks (WE/TM): The adapter is designed on the millimetric geometries of the AAP-01 Action Army magazines. If you want to mount it on a magazine shell of a WE or Tokyo Marui Glock, the tolerances change. You absolutely must insert a 1mm nylon shim in the rear of the shell, otherwise you will have major feeding and air leak problems.
Pressure (PSI) Adjustment: HPA is powerful, but pistol mechanics are not tanks! Adjust your HPA pressure regulator between 80 and 120 PSI maximum. Exceeding 140 PSI will not make you shoot further, but will literally explode the air block of the pistol or the adapter seals!
