It is not the same as the Glenfield Model 20 (Marlin 780). The Model 20 is a bolt-action rifle that fires primarily the .22LR rimfire cartridge, but also the .22 short, and the obsolete .22 long (all rimfire cartridges, and can all be fired in the same gun). Produced by the Marlin Firearms Company of North Haven, Connecticut, it was in production from 1960 to 1966.

Uses

The Model 20 is well-suited for small-game hunting and vermin control, as well as a target practice gun.
