Are you talking the 1980s version or the old humpback recoil operated version? If it's the 19980s version, it is just an 1100 with a hardwood stock. Excellent guns IMHO. Remington's first attempt to lower costs and the metalwork was still great. 1100 parts will fit. If it's the old humpback I, different story. Lots of people love the old recoil operated John Browning design, but I'm not one of them.
What could have happened... did.
