Ok guys here is my journey with me CMMG LR308 build so far
1) lower was off spec had to send it out to CMMG took about 4 weeks to get it back
2) LPK pin for the bolt catch cracked and had to order another one ;/
3) bolt catch was not working cause the a2 screw was too long that i was sent from fulton

and now!

I keep getting a jamed case after every shoot it refuses to extract and the rims of the rounds crack when the bolt gets to it so my questions is do you think maybe its these new ammo im trying out its called Privi Matched 308 from Midway they claimed its good stuff :mad:
Please advise guys please

Who's barrel did you get? Have you inspected the chamber for straightness, scratches and whatever that's not norm?

I've shot the Privi stuff, but in 223 and it seems to be OK, no over pressure sign and accuracy is acceptable.

its a factory DPMS upper no signs of scratchs in chamber im going to try a different brand of ammo and see how it goes

What's the barrel length?
What's the gas system length?

Sounds over-gassed.
