Tossed out the oring monkey kit... ordered a full rebuild kit from Boss and the issue is resovled. For sure a tighter bolt-bolt guide fit... my guess is it was allowing premature venting during the forward stroke of the bolt... and not getting proper shot to shot consistency.
I swapped them all, including the regulator piston orings (ordered separately).
While I don't know which one was the culprit, the gun shot like a champ this weekend.
