The Remington Model Four is a semi-automatic rifle manufactured by Remington Arms from 1981 to 1987. It features a gas-operated action with a gloss-finished walnut stock. Unlike most Remington rifles, the Model Four spells out the number and is marketed as the Model Four not the Model 4.
The Model Four, like the Model 7400, is similar to the Model 742; according to an article in Popular Mechanics, the Model Four has a "smoother action and stronger lockup".
