You can also slide a piece of 1/2 inch foam (like from those cheap sleeping bag mats) under an elastic Allen stock cartridge holder. Makes a nice cheek piece and you still use the cartridge holder. Cut the foam about 4 inches wide and 7 to 8 inches long so it slides under on both sides of the stock. I use it on my 30-30, 45/70 and just put one on a used 270 I bought because it has the high rings on it.
