Product Description

    NEF Topper Model 58 20 Gauge Single-Shot Shotgun, 24" Ported Barrel, Rifle Sights, 3" Chamber

    This New England Firearms Topper Model 58 stands out with its factory-ported 24-inch steel barrel, rifle-style open sights, and transfer-bar safety introduced during the 1974–1981 production run. Chambered for 3-inch 20 gauge shells and marked “MOD” (Modified choke), it blends the simplicity of a break-action single shot with features aimed at slug hunters and varmint shooters.

    What’s Included

    • NEF Topper Model 58 20 Gauge single-shot shotgun

    The 24-inch steel barrel is factory-ported to reduce muzzle rise and marked MOD (Modified choke), delivering consistent patterns while remaining slug-friendly. A modified choke designation from the factory further supports its dual role for small game and deer.

    Rifle-style open sights—a ramped front blade paired with an adjustable rear leaf—are uncommon on most Topper variants. This sighting setup, together with the ported barrel, signals NEF’s intent for precise slug placement at typical hunting distances.

    The break-action design features an external hammer and single trigger. A transfer-bar safety, protected by U.S. Patent 3,988,848, blocks the firing pin unless the trigger is deliberately pulled, adding a modern layer of safety to a traditional platform.

    Constructed with a satin-blued steel receiver and a matching barrel, the shotgun wears a dark-stained hardwood pistol-grip stock and semi-beavertail fore-end. A ventilated recoil pad and sling swivel stud round out a field-ready package.

    Made in the USA during the late 1970s and early 1980s under the revived New England Firearms marque, this Topper Model 58 reflects the transitional period following Harrington & Richardson’s reorganization, giving collectors and hunters a practical piece of that history.
