Just bought a tm ksg, and it's having issues firing, am I been a melt by doing something wrong. Gassed it up loaded the shell into right side racked it and no bbs are firing when I eject the shell one bb remains into what I can guess is where they should be loading could it be a dodgy shell or is it more serious? Its going back to the shop just wanted some insight from players on here searched the forums but couldn't find the answers I was looking for thanks Im advance for any helpful replies
