H&R Model 176 10 Gauge Magnum Single-Shot, 36" Full Choke Barrel, 3 1/2" Chamber, Color Case-Hardened Receiver
This Harrington & Richardson Model 176 is a United States-made, 1970s-era 10 gauge Magnum single-shot with a long 36-inch barrel and a 3 1/2" chamber. It features a fixed Full choke, a color case-hardened steel receiver, and a top-tang break-action release. The hardwood stock wears an H&R-logo ventilated recoil pad with a white-line spacer, and the barrel carries the original rollmark stating its chambering and choke.
The break-action design uses a single trigger and an exposed hammer with a spur for positive control. The matte blued, round-profile steel barrel has no rib and is rollmarked "MODEL 176 10 GA. MAGNUM 3 1/2" CHAMBER FULL CHOKE." The forend is secured by a single side screw into a barrel lug, and the length of pull measures 13.5". An AR-prefix serial is present, consistent with the 1970s production era.
Built for the 10 gauge Magnum, this Model 176 offers a straightforward, one-round capacity and a fixed Full choke tailored for tight patterns. The color case-hardened receiver contrasts cleanly with the blued barrel, and the uncheckered hardwood furniture provides a simple, functional grip profile. The top-tang release allows quick opening and closing of the action.

The 36-inch barrel is a key feature on this Model 176, combining a long sighting plane with a fixed Full choke. Its 3 1/2" chamber is set up for 10 gauge Magnum loads, and the round-profile, matte blued steel barrel omits a rib for a clean top surface. The rollmarks explicitly note the model, chamber, and choke.
The color case-hardened steel receiver complements the blued barrel and uses a top-tang release for the break-action. The exposed hammer with spur and single trigger provide a straightforward operating interface consistent with H&R’s single-shot design.
Furniture is uncheckered hardwood with a forend held by a side screw into a barrel lug. At the rear, an H&R-logo ventilated rubber recoil pad with a white-line spacer is fitted, and the length of pull measures 13.5". Capacity is one round, as expected for this action type.
Made in the United States during the 1970s, this Model 176 carries an AR-prefix serial consistent with its era. It is a simple, purpose-built 10 gauge Magnum single-shot configured with a 3 1/2" chamber and a fixed Full choke.
