"You can buy no better gun for target work and all small game up to 200 yards. Without change of mechanism it handles .22 short, long or long-rifle cartridges, perfectly." - Marlin advertisement, 1910
About 8,000 Model 20 rifles were made between 1920-1922. Slight receiver variations mark the difference between the models. PGW carries only the stock for these rifles (one universal style fits each model).
