KWC mini uzi mag leaking
Once I insert the CO2 cartridge into the bottom of my magazine, hand tighten the screw, then twist with the wrench to pop te Cartridge seal, CO2 blows out from the small release hole in the bottom of the screw. Any idea's? My new mags were doing it when I first got them, but now they don't last time I fired my gun a couple days ago.
