They labeled a 6.5 Grendel I think it was as a 7.62 bolt.
. 6.5 gr and 7.62x39 are the same bolt face, FYI

OP. No idea if the ramps are misaligned. It may be the upper that is cut incorrectly.
Is see that the barrel’s ramps and the uppers ramps are off slightly.

The barrel has an index pin on the top of the barrel that aligns the barrel and upper via a slot in the upper.

Swap your BCG and see if that helps.
Also, really clean that barrel and chamber. May have an imperfection in the chamber that is messing you up.
