The Armscor TK 20 Gauge Single Shot Shotgun brings straightforward, reliable shotgun design to hunters and sport shooters who value simplicity and value. Built by Rock Island Armory under the Armscor brand, this Model TK105 features a 20-inch barrel with a vented rib and hard-chromed interior, delivering clean lines and practical durability in a package that handles game and clay without excess weight or complexity.
Single-shot shotguns never went out of style for good reason: they're intuitive, durable, and put the focus on marksmanship rather than firepower. The TK105 chambers 3-inch 20-gauge shells, giving you genuine versatility for upland birds, small game, and light hunting roles. At just over 5 pounds unloaded, it swings naturally and won't tire you over a day in the field. The silver anodized finish and polymer stock resist weather and handling wear, while the front bead sight provides a clean, uncluttered sight picture.
Two interchangeable butt pads come standard, letting you dial in the length of pull to your frame and shooting style—a thoughtful touch that ensures a proper fit without custom fitting costs. The slug choke makes it capable for deer and larger game when the moment calls for it. Whether you're teaching a new shooter, pursuing upland birds, or keeping a reliable backup gun in camp, the TK105 delivers honest performance without complications.
