Finally got the bugger out. Besides it being a slightly "pressed in" fit (which might explain why there's been a few of these that arrived to customers with cracks by the front action screw), it's also glued in with what looks like SuperGlue. I had to mill out the full width of the lug on the front side about 0.400" before I could even get it to wiggle any to break the glues bond and finally get it out.

Soo...if you have machined your action to accept standard 110 recoil lugs and want to order a Boyds stock, ask them not to put a recoil lug in it so you don't have to go through this headache like I did.
