This Marlin manufactured late variation receiver sub-assembly has the full length extractor groove which became standard in 1971 and is for the Glenfield model 20 bolt action rimfire rifle. The receiver sub-assembly consists of the late variation receiver and the trigger stud. The overall condition is very good retaining over 95% original blue finish with light wear. This is the only part on the Glenfield model 20 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.  (file photo)
