Action Army AAP-01 Charging Handle Type 1

Great for quick speedy players.

I love KWA, but they really dropped the ball on the TK-45 and Ronin 47 hop chambers. Seriously, these things are horrible. This Airtech modification fixes *most* of the issues. Adding a clip to the hop wheel fixes the rest of the issues. My Ronin 47 is now an absolute beast. The Beastliest Beast in all of Beastville. When I hop it, it stays hopped. Installation took all of 10 minutes, and most of that was looking for a clip in my "misc parts" drawer (the orange-y colored piece). Please note that the zip tie is only to keep the unit in place until the superglue dries. If you're worried about supergluing something to your hop chamber, remember that exposing a heat gun to it will break down the glue and you can remove the mod. Not that you'll want to. Good $15 investment.
