    Do not use the O-Ring with with the 5 Coil spring (for at least 1,000rds if at all).

    I get those markings when I shoot that old WOLF M-193... That ammo with the really fast propellant. That'd be from high chamber pressure.
    I agree with these guys, it is high pressure causing the marks

    The 6.8 is the best choice for hunting deer and hogs with an AR15.

    If I had a gun that needed that stupid o-ring, I'd get rid of it.

    These 3 statements pretty much summed up what everyone else said. I'm going to remove the O-ring as well.

    Big thanks to everyone for the replies.
