I picked up a good condition 870 recently for a good price. My face sits too low on the stock. I put on a 1/4" CheekEez pad on the stock, and it still isn't quite high enough for me. I see on Remington's site a "stock spacer" that goes between the stock and receiver. It looks to be metal. Does anyone know if it is metal or plastic? If it's plastic, I'm thinking I could cut the top half off and put the bottom half between the stock and receiver to raise it a bit (like a Benelli or my former Beretta 391). Of course I could always buy a Monte Carlo stock, but am trying to not spend that much if I don't have to.
