I attempted to take the lock from the rifle. Took out the left side screw that I think holds the lock to the stock, also a long screw from a band on the wrist of the stock, top. Unable to get the lock to budge. Is there a secret to getting those things off the rifle. It's probably never been removed. Did not want to mar the stock finish or the metal taking it off. Wanted to check the lock for cleaning and lubing. Any help appreciated.
