It only takes 10 minutes and a $7.00 part to restore the FTE error of the 64. I have 5 and all are different. models...64 c/w plastic mag and rabbit stock ( original 64) a 64 converted to metal magwell and mag. Cooey 64A , Lakefield 64B and Sears 8C (64C)...each one cycles and operates great if they are cleaned regular and the ejector is not broken or bent when the barrel is removed. The early models used a wire ejector while a flat metal one came along in the second remodel.
the cooey 60 is a great long lasting and seems collectible model bolt action , as is the model 600. Both guns are in the neighbourhood of a $125-$150 depending on year and condition. I have seen them on here sell for over $200.
