So I have owned my L96 for about four year now and fired around over 1000 rounds through it. I was going to take it to a scenario game, but when I took it out to do some target practice. The bolt randomly snapped back forward and automatically shot a bb after pulling the bolt back. I thought it was a jam or something but when I pulled it again it once again snapped back forward and fired. I took apart the sniper and found the black plastic box housing the trigger to be cracked. My friend said it might be the trigger sear, since that is how his L96 broke. I don't what caused this and I was wondering if there is any hope of repairing it? I really love this gun.
