I have a faxon barrel and a tool craft .125 bolt face depth bcg. that works great. but I was wondering if anyone knew what the correct bolt face depth is for the PSA barrels.  I contacted PSA and they said an engineer would get back with me but this has been a few weeks now.  I want to build a pistol but their bolts are out of stock and I want to make sure headspace is correct. any information would be greatly appreciated

There have been several threads where forum members state they’ve used bolts from Aim Surplus and tool craft with their PSA 7.62X39 AR-15 uppers.  To my knowldege the only 7.62X39 that doesn’t use a .125 depth bolt face was the original Colt 7.62X39 AR-15’s.    I think the PSA upper which uses AK pattern mags uses only a Hybrid PSA bolt.  

Maybe someone else will chime in.
