This Marlin manufactured early variation receiver does NOT have the full length extractor groove which became standard in 1971 and is for the Glenfield model 20 bolt action rimfire rifle. The overall condition is very good 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.
