I did the same thing to get it pried off. Eventually I got it off without damage.Yes, mine was spot glued and screwed. I worked a razor blade deeper and deeper going around and in between the stock and buttpad. Eventually it’ll pop off. They used a nickel to quarter sized dab of epoxy at each screw and ran the screws in. I’m putting my own spacer setup in it. Haven’t done it yet though. It’ll use recessed nutserts in the first 1/4 spacer which will be permanently glued to the stock. Additional spacers and buttpad will get screwed on with machine screws.
