I posted that the Tang Screw in my RRB was stuck, butt stock was loose. I turned it up side down and for 4 days put drop of pent. oil on the head. It went somewhere ?, I then put it my vise on the drill press, got a hard screwdriver head that fittted the beat up screw slot, run the table vise up tight to the chuck, with key in the chuck it finally turned out. I see the head on the screw was over size when the factory put it in and now I will get the head rewelded up . The screw is hard a reciever on a Enfield. as of now it will tighen the stock up. Just a way to do it with simply tools, Thanks- Joe
