This Marlin manufactured first variation receiver lacking the hold open notch on the inside left wall of the receiver and lacking the serrated lines on the top of the receiver between the scope mounting grooves is for the early Glenfield model 75 semi-auto rimfire rifle and is in very good condition retaining most of its textured original black finish with light wear and handling marks. This is the only part on the Glenfield model 75 rifle that is tracked as a firearm therefore it will need to be transferred through an FFL dealer. Receivers do not qualify as a C&R based on BATFE's guide lines. (file photos)
