I have a SBE I. It is 3 years old and has had probably 5000 rounds through it. Zero problems until last week. I have a surecycle in the stock and it has been there since I bought the gun. Works great. I dropped my gun and broke the surecycle tube even with the receiver, and had to have it replaced. I sent it to surecycle and they replaced it for me. I got it back and put the gun together and now it will not cycle shells.
If I put a shell in the magazine and push the button by the trigger guard the shell shoots out onto the carrier just as it should. Then if I manually pull the bolt back to load the shell, it hangs in the rear position. If I push forward on the bolt handle, or push up on the carrier it will chamber the shell and close properly. It does the same thing when I shoot. The first shell is ejected, and the next shell gets stuck on the carrier with the bolt locked back.
My gun is very clean right now and well oiled. Much cleaner than it usually is. I am not sure what the problem is, and I am in the middle of hunting season so I hate to have to send it off. Any ideas?
