Inexpensive .22 semiauto rifle based on the Marlin Model 60. Sold through mass-market stores.
The Glenfield 25 was manufactured from 1979 through 1982. Some would suggest the Marlin Glenfield 25 was produced from 1972-1982. Regardless, the Glenfield name was cancelled in 1983. The rifle continued as the Marlin Model 25 until 2003, which then became the Marlin 925. Thousands were produced so YES it is common to find a Marlin-Glenfield Model 25. How many original matching Marlin scopes made it so far with the rifle however is another story. I have not seen many with the matching scope so this may be uncommon. The Model 25 is a robust and classic rifle. Enjoy :)
I found the value of a Marlin/Glenfield (similar serial) to be at about $2,700. I'm looking too, but that's the price I was able to find.
