Marlin Glenfield Model 60 .22 LR Semi-Automatic Rifle, 22 in Micro-Groove Barrel, JM Proof (1977)
Produced in 1977, this first-generation Glenfield-marked Model 60 pairs Marlin’s iconic Micro-Groove 22 inch barrel with the original 14+1 round tubular magazine. A JM proofmark on the barrel confirms manufacture at Marlin’s North Haven, Connecticut plant, and the receiver is factory grooved for 3/8 inch tip-off scope rings. Birch hardwood furniture with pressed checkering keeps weight low while preserving the classic look that made the Glenfield line a mainstay of affordable rimfire shooting during the 1970s.

What’s Included
- Marlin Glenfield Model 60 semi-automatic rifle
This rifle retains the desirable 22 inch Micro-Groove barrel, featuring 16 shallow lands for consistent .22 LR accuracy. The full-length tubular magazine holds 14 rounds, an original capacity that was later reduced on post-1980s variants.
The alloy receiver is black anodized and grooved to accept standard rimfire scope rings, giving the shooter easy optics options without aftermarket modification. A cross-bolt safety, black alloy trigger guard, and alloy receiver assembly complete the lightweight action.
Its one-piece birch stock wears a walnut-tone stain and pressed checkering on both the fore-end and wrist. A black plastic butt-plate and straight comb replicate the Glenfield economy styling of the era while delivering a 13.75 inch length of pull.
Collectors often seek pre-Remington JM-marked Marlins for their build quality and historical significance. This 1977 example combines those credentials with the enduring functionality that has kept the Model 60 in production for decades.
