I bought a Choate cheek piece for my Survivor but found it needed modification to fit. The Choate varmint stock must be about a 1/4" thicker. I thought about filling the gap but didn't want to add weight so I decided to try heating it and bending in the sides. I warmed the oven up to 190 then increased 10 degrees until I could bend in the sides. At 350 I finally was able to bend in the sides and now it takes firm pressure to put the cheek piece on the Survivor stock. Since the Survivor stock is hollow I replaced the screw with a bolt, nut and washer.
