I have a Finnfire P94S, love it very much. :t However, when I set the headspace, the barrel seems to gradually slip forward after shooting a couple hundred rounds, then the bolt will close a a .045" no-go guage
, and then I have to reset it so the bolt won't close on the no-go. I have degreased the barrel and receiver contact points, and it still slips when the clamping screws are torqued to 100in/lbs
. Anybody have a cure for the slippage?
