Got my PP2k straight from the manufacturer. I enjoyed it from first time, after a couple of magazines, I broke an internal plastic piece. The manufacturer sent me the metal one (had to pay). From stock the PP2k lifts 0,40 g with no problem usong CO2 magazines. With gas magazines, it lifts up to 0,36. Using this kit is crazy. You don’t now if you don’t have it. Plug and Play. Literally. 💯 Recomended
