Have any of you had the stock off of your Merkel 140 Double rifle? I think I know what screws to remove, but not sure how to get the 2 screws out of the bottom plate. I ground down a screw driver to fit them, but they are so tight they won't budge. Are these installed with loctite? If so, how can I get them to turn? Also, what is the thru bolt, coming in from the rear of the stock, attached to? Does it also have to come out?

Thanks!
