Hi jurassic, what pressure signs did you see? I never actually ran a go/no go gauge on my upper, just measured where the 123sst's were hitting the lands (2.300") and case capacity after firing (35.6gn H2O with Hornady brass) ....both those numbers seemed legit, but I did have some case swiping. Switching to the hard use bolt with a M16 carrier cured the swiping, and it really smoothed out the action. Anyway, I hope RedX takes care of your issue!
