when i got this gun it worked great. rpm was amazing which was around 10bbs per second. when i was using it the but stock got loose and i couldent tighten it. then a sprin came loose in the internals and jamed the gears. i got it out then it worked fine. then it just started grinding. goes to find out it was the spring to the latch that holde the piston in place and it keepd hitting the gears. this gun was fun but from fhat happened i will NEVERE buy it again.
