A lot now on my usp compact, when I pull the trigger the bb will get stuck in the hop chamber. If I pill the trigger another few times, the bb's will stay in the barrel and not come out. What is wrong. Help.
Could be the hop is set fully on, as on a GBB pistol that is likely to stop the BBs exiting the barrel. I had this problem with an after-market hop rubber I bought for my TM G17. Fitting it stop the bbs getting past the bump in the hop rubber as it was too big to fit properly in the hop chamber of the gun.
