As a Glenfield economy-line variant of the Marlin 336 pattern, this Model 30A offers the solid-top, side-eject receiver design favored for its durability and ease of use. It includes a side loading gate and a standard loop lever, and it retains the traditional half-cock safety system without a cross-bolt safety.
The 20-inch round carbon steel barrel and blued steel receiver form a classic carbine configuration. Feeding is via a full-length tubular magazine with a 6+1 capacity. Sighting equipment consists of a ramped front sight and an open rear sight; the front sight hood is not present.
The hardwood two-piece stock and forend feature a pistol-grip profile with pressed checkering and wildlife motif panels, along with a black polymer buttplate. The length of pull measures 13.0 inches, providing a compact, handy fit.
Practical upgrades include an installed Weaver-style scope base/rail and a clamp-on hammer spur/extension. These additions enhance mounting flexibility for Weaver-pattern rings and improve hammer access while maintaining the rifle’s traditional handling.
