This Mossberg manufactured receiver is for the model 46B bolt action rimfire rifle in 22LR caliber and was manufactured circa 1938-1946. This receiver is in very good condition exhibiting a mixture of thinning original blue finish with a brownish gray patina and having a few specks of light surface rust. This is the only part on the model 46B rifle that is tracked as a firearm therefore it will need to be transferred through a dealer. Receivers do not qualify as a C&R based on BATFE's guide lines.
