Marlin Glenfield Model 30A .30-30 Lever-Action Rifle, 20" Barrel, JM-Stamped, 1975 Production with 4× Scope
Produced in 1975, this Glenfield-marked Model 30A combines the proven Marlin 336 action with economical birch furniture and pressed checkering. A JM-stamped North Haven barrel, pre-cross-bolt safety receiver, and factory side ejection set the foundation, while an installed Glenfield 4×32 scope delivers ready-to-hunt capability. Clean metal, sharp wood, and a classic 20-inch .30-30 barrel make this rifle a straightforward, collector-friendly example of Marlin’s 1970s retail strategy.

Serial prefix “25” dates this rifle to 1975, placing it firmly in the pre-safety era that many Marlin enthusiasts prefer. The half-cock hammer notch serves as the only safety, maintaining the traditional lever-gun manual of arms.
The blued carbon-steel barrel measures 20 inches, giving the rifle a handy overall length while preserving the classic .30-30 ballistics hunters expect. Side ejection through the solid-top receiver keeps fired cases clear of optics and allows the low-mounted scope to sit securely above the bore.
Birch hardwood stocks feature Marlin’s 1970s oak-leaf pressed checkering and a satin lacquer finish. A 13.5-inch length of pull and pistol-grip profile provide a comfortable fit without adding unnecessary bulk.
Iron sights remain in place—a hooded ramp front and semi-buckhorn rear—so the rifle can transition between glass and irons with ease. The included Glenfield 4×32 optic adds magnification for longer shots yet maintains the rifle’s quick-handling character.
Built on the same action as the flagship Model 336, this Glenfield 30A delivers reliable six-round-tube capacity, smooth lever throw, and the rugged JM-marked craftsmanship that has made Marlin a staple in American deer camps.
