The Marlin 60 14+1 capacity .22 LR rimfire rifle was developed in 1959 and put in production the following year, hence the “60” name. The direct blowback semi-automatic has a walnut-laminated stock. The barrel is 19” long, micro-grooved and given a protective precision crown. Underneath is the 14-round tubular magazine. It has a cross-bolt safety and an automatic “last shot” bolt hold-open. Overall length is 37.5”, length of pull is 13 1/4″ and weight is 5.5 pounds.
The Micro-Grooving deserves a bit more exploration. Marlin introduced Micro-Groove rifling and capitalizes the individual words with pride. The 1:16” twist ratio bore has more grooves – 16 to be exact – than most other guns and thus more lands (the non-grooved portions) too. This means less bullet distortion, a tighter gas seal, improved performance and improved accuracy that results in tighter groups.
