you can't wear one of them out.i've had one since i was a kid it is still a tack driver and it has had thousands of rounds put through it. i di have to replace the bolt and firing pin spring a couple years ago. i ordered al my parts from numrich ( i think that is spelled right). they carry quite a few parts for them.also beels pawn in coweta has parts.
Thanks for the heads up....I was a bit worried when I downloaded that schematic from Remington that had a big stamp "Parts no longer available." I used extra caution when cleaning.
