I have one. It is great fun to shoot but not acurate. I have a high presssure air compressor so I switched to high pressure air and it runs much cleaner. Its just a paintball gun converted to shoot pellets and I would say it shoots 4 inch groups it 25 yards. Did I say its great fun to shoot. full auto you can pepper a cinder block at 25 to 30 yards so its not a gun for hunting unless you like the shot gun afect.

PS The first one I recieved would jam all the time. Returned it and the new shoots great no problems.
