    I feel your pain there is so much to learn about these damm rifles.
    I am an AK person so all this is a overwhelming to me.
    Just picked up a BCM upper and will be adding a lower soon, most likely a Quinten Defense billet but I have had great help from Packerfan ( superbowl champs again I think? ) I was born in Appleton Wi. so my religon is Green Bay Packers from the Father Vince!!!!

    If the BCG is from a reputable manufacturer, and going in an upper from a reputable manufacturer, you shouldn't ever have to worry about it.

    BCM upper and bolt carrier with CMT bolt. Quentin Defence billet lower.

    Think it is worth a check by some one with a set of guages?

    Yes! I'd also have them verify whether it is a 5.56mm chamber or a .223 chamber while your looking.
