Matt,
Is your stock a IR replacement?

Was hoping the Recoil Plate replacement would have helped. Too bad it didn't.
Your likely looking at having to clear some wood out from where the 3 circular impressions I noted above are located.
It must need some relief, with it showing that much compression.

What do you think? A little at a time? I'd try a Dremel where the drain hole end of the integral housing tube is hitting with a rotary type sanding bit.
And maybe some 80 grit wrapped on a file on the back / where the 2 circular impressions are.
Maybe try some flour or chalk on the wood or metal to pin point the contact area's first.

Just some thoughts......

Safe Weekend,
