This Winchester manufactured receiver is for the field grade model 120 slide action shotgun in 12 gauge and is known as the early variation designed for the ejector retaining pin (not included) and has a serial number below L2,000,000. This receiver is in very good condition retaining about 97% original blue finish with a few light handling marks and honest light wear. This is the only part on the model 120 shotgun 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. Note: a receiver with serial #L2114967 was found with the retaining pin type system.
