Of course if it closes on a NoGo it's going to close on a Go.
If it closes on a NoGo, try a Field. NoGo isn't great, but at least you can size brass to fit it and it isn't a safety hazard to fire new brass in it. If it closes on a Field, other than setting the barrel back, it's trash. I only know of one guy who is willing to set AR barrels back and it costs more than most barrels are worth.
