Hi Andy,

I talked to S&W yesterday and they want the rifle back for evaluation. I've also heard that some bolt carriers are out of spec
and need to be replaced. I first wanted to see if it was a common problem with the S&W crowd.

The strange thing in this is that it functions fine with another bolt assembly (Ruger in this case) but not with its own S&W factory bolt. Never had a problem before.

When I researched the costs of a new bolt assembly, I think I'm better off sending it in to S&W than incurring all the costs and experimenting to get it to work reliably. The rep I spoke to was very knowledgeable about the rifle series and said right off "You definitely have a gas problem. Let us take it back and see what we find."
