I had the same problem, I removed the wood and cleaned the metal. It was tough to recock the ejectors but by placing it on a wood block and doing one at a time I did it. Has worked fine sense then. If it is an early model watch the reinforcement that helps hold the forend on the metal. It can be tough to put back in place. I put it in place first and tighten it last. The type that attach to the front of the iron cause no problem.
