So I installed the shim. It did not lift the barrel enough to clear the front pressure point. So then I cut another set of shims and put two shims in there. At that point it lifted the barrel high enough to get it off the front pressure point but still not high enough to get the sides of the stock off the barrel. I didn't bother to cut a third set of shims because I'm figuring that two shims is already too much as it is.

Any ideas?
