This Remington manufactured receiver cover assembly is for the Nylon 77 semi-auto rimfire rifle and is equipped with the complete rear sight assembly, cartridge feed guide spring and both cover screw nuts and is in very good condition retaining most of its original blue finish with some light wear and a few specks of light surface rust. This receiver is the only part on the Nylon 77 rifle that is tracked as a firearm therefore it will need to be transferred through a dealer. Receiver covers do not qualify as a C&R based on BATFE's guide lines. (file photos)
