What’s Included
- Harrington & Richardson Model 176 Magnum 10 Gauge single-shot shotgun
The Model 176 Magnum is built around a robust 10 gauge platform designed for 3 1/2 in magnum shells. Its 36 in steel barrel uses a fixed full choke, paired with a blued finish, to deliver the long-barrel configuration associated with this model.
The action is a single-shot, break-open design operated by a right-side thumb side-lever, with an external hammer and a single-action trigger. Safety is provided by H&R's transfer-bar/firing-block system (U.S. Patent 3,988,848), a hallmark of the brand's later-era single-shots.
The steel receiver wears a color case-hardened finish, and the stock set is walnut-stained hardwood. It features a straight-comb pistol-grip butt, a semi-beavertail fore-end, and a factory H&R-logo ventilated rubber recoil pad with a white line spacer. Length of pull measures 13.0 in.
Design elements noted for this model include a self-adjusting barrel latch and three-piece takedown. Markings include "HARRINGTON & RICHARDSON, INC., GARDNER, MASS., MADE IN U.S.A." on the receiver; the circled P proof is on the barrel near the chamber.
Capacity is 1 round. The overall configuration reflects H&R's 1970s production with U.S. manufacture and the brand's established single-shot operating system.
