Gunman, I guess I probably could have better described to sound. I removed the extractors and associated parts and when tapped the sound is essentially a buzzing sound at the bore end of the barrels as opposed to a rattle. I'm just trying to gain some knowledge here as I'm on my own. I'll have someone check it out. Lot's of work on the gun up to this point so rather frustrating, but at least I picked up some good knowledge out of the deal.
