The upper is something I put on. Only the lower is s&w.Before throwing parts at it, maybe a contact with S&W? Warranty work, maybe? Just a suggestion.

Wish I had one to try. Unfortunately I don't.I had a gas block that was misdrilled once. Gun ran fine with suppressor; but would short stroke without. Gas block port was drilled in wrong place. Try a suppressor if you have one and see if it cycles.
I do. Have someone that's gonna take a look at it today. Hopefully get it narrowed down to the cause of the problem.do you have a spare bcg to try?
How much to have you open up the gas port and when would be a good time to bring it up there?
