A flat washer MUST be used with the factory stock bolt. A washer is included with the stock. The Hogue stock is designed to reuse the factory stock bolt with the addition of the flat washer.
The stock bolt (not included) is a 5 1/2"long 5/16" - 18 TPI with a flat washer, available at any quality hardware store, gun parts retailer, or from Mossberg directly. You must use this bolt when changing from a pistol grip or Tamer to a butt stock. Tamers/Pistol grips use a short bolt that is included with the Tamer (no washer needed).
