This Remington manufactured early variation rear peep sight assembly is for the model 341-P Sportmaster bolt action rimfire rifle and is in very good condition with light wear and a few specks of older rust. The early variation rear peep sight assembly has a shorter extension of the arm over the top of the receiver than what is seen on later manufactured rear peep sight assemblies.  (file photo)
