you were the one with a unimount and 3k tank right? when you brought it to me, you werent screwing in the unimount all the way, thus the reason for the dropoff. it may have gotten so bad during a game, your bolt may have not had enough air to fire the ball, but instead just pushed it into the barrel and when you fire again, the second ball slams into the first and it appears to be 'chopping'. this is most likely the answer, since you say that it only chops at the end, not a combination of dropoff and chopping. i was there today as well, you should have brought it back, i would have done everything i could to fix your 'led not lighting up' problem...
i cant 'fix' your gun if you dont 'bring it to me'
