Description

Marlin 60SB

The action design is a self-loading, straight blowback operation, with right-side ejection. The receiver top has a serrated, non-glare finish. The receiver is held in the stock by front and rear machine screws through forearm and the trigger guard respectively (later models add a wood screw behind the trigger guard to reinforce the wrist of the stock). The receiver is grooved for a scope mount. For use without a scope, the barrel features an adjustable open rear light and a ramp front sight. The charging handle is used to load the first round from the magazine and can be retracted and pushed in as a manual bolt hold-open feature. Current model has an automatic “last-shot” bolt hold-open device with an external lever in the front of the trigger guard to release the bolt. Earliest Model 60s did not have a bolt hold-open; first the manual, then in the mid-1980s the automatic “last shot” hold-open were added. The rifle has an easily accessible cross-bolt safety located above the trigger. When disassembled, the trigger guard with trigger and safety remains in the stock.

Marlin uses their proprietary Micro-Groove rifling in the Model 60. The twist rate is 1:16 inches, right-hand. Micro-Groove rifling uses 16 small lands and grooves rather than 4, 6 or 8 deeper grooves used in most rifles. This increases the accuracy of the rifle by lessening deformation of fired bullets traveling down the barrel. Although the Model 60 is one of the least expensive .22 semi-automatic rifles sold, it has the reputation of being one of the most accurate rifles out of the box, with no modifications necessary.

Unlike some competing .22 semi-automatic rifles, such as the Ruger 10/22, there are relatively few aftermarket accessories sold for the utilitarian Model 60.

The Model 60 has been sold in over thirty-five variants, and is one of the fastest-selling sporting rifles ever, as of
