I purchased one of the Briley extended bowl release button faces and while trying to drive out the pin that holds the whole assembly in place, I just can't get the thing to budge. I'd picked up a Guns Digest shotgun book awhile back that covers this model, and there's nothing tricky indicated aside from just turning the receiver over and driving the pin out. No hydraulic press to try, I did give it a shot of PB Blaster in hopes that the pin would give in and slip out, no luck there however. Has anyone removed this? It just feels like I'm pounding that punch awfully hard without any response.
