I bought this a month or so ago and hated it because it wouldn't shoot anything but the good stuff.
I did alittle research and ordered from CSS a reliability kit with spring and puck, a trigger relocation kit, and some cool hardware, ATI stock.. Did it myself, was alittle work but I love it now !! I tried some 100 bulk pack wally world elcheapo shells and it dumps the mags flawlessly.......
