In this Full Auto Fun Field Test Shooting video I bring out my original Umarex Walther PPK Blowback CO2 BB Pistol. The PPK I converted to full auto and that started it all off by being my first YouTube video upload. Wow, that was a while ago now!
I do have to say, modifying the PPK to Full Auto is not recommended, mine originally worked well but the heavy blowback in full auto eventually broke the firing pin setup and I lost it somewhere in my back field. I had to Macgyver a bolt in place to kind of work but now my Full Auto Modded PPK shoots out of control, what I mean by this is when I press the trigger, it does not stop shooting until all the BB's are gone. Safe, I don't think so!
My suggestion is to leave the Umarex Walther PPK as is, it truly is a an awesome CO2 Blowback BB replica with some really decent blowback recoil in a small airgun.
