Is there any of you guys familure with the Remington Nylon 66 22 long riffle? I picked one up for my son the other day I got about $250 in it. I think I did ok mine is the Mohawk Brown, just hun , no scope. It is missing the top screw on rear site and the wind adjustment screw is there but the head is broken off. Is there somewhere I could purchase parts for my son’s nylon 66?
