Here is how the action inserts into the stock:







As you can see - there is a square base attached to the bottom of the barrel that the bolt screws into. I could put a rubber washer on that square base to raise the barrel, but I'm afraid that the only point of contact will only be that base and it will be too unstable.

My plan as of now is to cut some aluminum shims to put in the pocket forward of where the base is to raise the barrel so it doesn't touch the stock from that point forward.

Do you think this is a good idea? Any other suggestions?

Thanks in advance.
