Where can I find parts for a mossberg 100 atr I need the screw and spring that go to the bolt release. Mossberg will not send me the parts they said it was factory installation only and this gun is not in warranty anymore and they want to much to fix it, and the rifle belongs to a friend of mine and he really doesn't have the money to send it off. So any help you guys could give me would be greatly appreciated also I already checked with Numrich and they don't carry parts for this rifle.
