Harrington and Richardson Topper Model 158 single barrel 20 gauge shotgun, serial number AJ293333. Long out of production, the Topper was one of the higher quality single barrel shotguns of the time. This fine American made shotgun is marked with the usual Harrington & Richardson Made in the U.S.A. stampings along with “20 GA 3” MOD” meaning it will take 3” magnum shells along with standard 2 ¾” shotshells. It is also choked modified for all around use. The barrel measures 28” and the stock retains the original Harrington & Richardson embossed recoil pad. The receiver retains about all the case hardened colors and the barrel shows nearly all the bright blue. The bore is excellent and bright. The stock and forearm have some minor surface marks only and one decorative brass inlay in the bottom of the pistol grip. The action is excellent with the rebounding hammer functioning correctly. The barrel to receiver lock-up is tight with no play in it. A useful utility shotgun that is also perfect for a safe first shotgun for a young shooter. This Shotgun weighs 6lbs 2oz. Serial Number: AJ293333. This is a modern firearm and requires a FFL transfer or NICS background check.
