Ok this is a brand new set up.I have a fail zero bcg and the palmetto premium upper with the fn barrel And geisele mlok rail.when I brought it to the range it fired twice then the bolt would not go into battery it was super tight. I will say when I check the head space it was a fine. I will post some other pics s of the bolt if anyone wants.

Not knowing anything else:

Pull it apart and clean it. Maybe a metal filling got into the locking mechanism?

Not sure I'd 'force' it into battery. At least not yet. Do you have another bolt, another upper, swap parts and see what works with what.

Strip and clean the bolt, is it me or are the forward assist serrations low on that bolt?
Look in the carrier Key for a a primer

Do you have a qd sling point on the back of your rifle where the buttstock goes?
Happens on one of mine it'll rub off after a few hundred rounds
