I have purchased nine shotguns from CSMC. Three original Win M21's and ordered six other new shotguns. Zero problems with CSMC or the guns. Customer service has been exemplary. Example: top barrel of an A-10 with 3000+ rounds through it had a 20% rate of piercing the primers ( on ONLY one brand of ammo). I personally took it back to them with the intention of leaving it for service. I was told to wait and they would see what needed to be done. Two hours later it was returned to me after the work and they had completely gone through the gun and test fired it (which I could hear going on) with more than a box of shells. New springs and other updates were installed. Zero cost to me. Buzz obviously had a very bad experience with them and understandably will no longer do any business with them. I, too, only have to be burned once.
