This Remington manufactured rear sight sub-assembly is for the Nylon 66 semi-auto rimfire rifle and is in very good condition with light wear and a few specks of surface rust. The only parts needed to make this sight complete is the rear sight rivet (we have a reproduction available which is sold separately) and the windage adjustment screw (which is near impossible to find).
