More photo's here: https://imgur.com/a/xdkwBXU Finished rebuilding a set of KWA ATP's. Got them all working with good cycling and good compression thanks to the aluminum piston head and mag shims! All come with: Gun and mag Aluminum Piston head (Preinstalled) 4x Mag shims (Preintsalled) Slim backstraps ATP B & C: - $97 each V.2; metal recoil rod, "safety" trigger, and orange threads ATP D & E: - $85 each V.1; plastic recoil rod and basic trigger. Orange cap removed Each ship in a USPS medium flatrate at $15. I can probably fit two in one medium if you're craving some dual-pistols.
