Blue Avenger, I like that laminated stock, got the same color on a Striker. Try polishing the inside of the receiver lightly with a Scotch Brite and check your firing pin and extractor. I had a bent and burred firing pin in a new, unfired bolt, replaced with a new, flat, polished firing pin.
Just recently took my Charger build to the range for a test shoot before making a few more changes. It runs good, so far. Details: Charger action from S&P, Fedderson barrel, BX trigger, Enoch Deep Six chassis. The bolt and receiver have been cleaned up and de-burred. So far, no FTF or FTE with CCI SV or Norma ammo and initial groups were okay.
