Just assembled an new .308 upper for a buddy built from all NEW parts. DPMS upper, DPMS BGC, DPMS 16 Oracle barrel.
Removed the extractor from the bolt and using the "GO" gauge, the BGC locks in nice.... BUT KINDA TIGHT pulling out?
Using the "NO-GO" gauge, the BCG will click but not lock and slides right out.
Is this the norm and are we good to "GO" for shooting or do we wear a face shield when we fire it and hope for the best?


 

I have the same observation with a Go/No-Go gauge on my build.

I brought it to the range and it was fine.

My DPMS bolt was tight with Go gauge.

Did you remove the ejector as well?

With the barrel installed on the upper receiver, I find it damn near impossible to insert the gauge into the chamber with ejector in the bolt.

All good to go, my dumb butt only removed the extractor and not the ejector pin.
