My ksc mp7 is a japan version. When I shot it in semi-auto mode, the bbs travelled less than a feet and fell onto the ground. Worse still, the bbs wee trapped between muzzle and barrel while I shot it in full auto mode. No bbs came out from the barrel. Bbs fell out from the barrel when I point the gun downwards.
May I know what's wrong with my smg?
What can I do to solve the problem?
Thanks in advance.
