Just finished a build on a Essential Arms upper and lower with a 20 inch barrel from Superior Barrel with a wylde chamber. Used the bolt that came with it and a BCM carrier. Can't get the bolt to lock up on a Go gauge. A dummy round locks up fine, but not the Go gauge (from BM, marked 223/5.56). Any advice appreciated. Thanks.

Did you take the ejector out?

I did take the ejector out.

Turns out that according to Superior, their chamber dimensions are quite tight and this is quite common. They use a different GO gauge for each bolt matched to the barrel.
