encore forend scews are 8-40 and you cant buy them locally, imagine that! i make custom forends so i found out the hard way you have to get them thru brownells or TC and they are about 6bucks plus shipping , the contenders take 8-32 i get them in ss at the hardware store for 20 cents each. as for the stock bolt im not sure hope this helps. daigneau also some guy on ebay sells 3 for 3.95 plus shipping.
