Old gun----new problem....Solution on Page 3

Just to make sure if you by chance have both a 7.62 X 39 bolt face Grendel and a standard Grendel. Make sure you are using the right bolt.

I think you have done this before but get some headspace guages and check the headspace of the rifle itself. If the rifle has the right headspace, my bet is the gas system is causing a problem.


LR1955

It is a complete upper from AA. I doubt it is a mismatch. I called them and described the problem but they never got back to me.
I will look into getting some headspace guages.

Thanks
