The Adamson SP 20-gauge over-under shotgun brings balance and handling to upland hunters and clay shooters who value a lighter swing and softer recoil without sacrificing versatility. Built on a steel receiver with a clean silver finish, this 28-inch barrel O/U delivers the classic lines and feel that make over-unders the preferred platform for bird hunting and sport shooting. The Turkish walnut furniture strikes a timeless aesthetic while the included rubber butt pad absorbs recoil, keeping follow-up shots controlled whether you're working through a covey or breaking targets at the range.
What sets the SP apart is the included five-piece choke set with wrench—you're not locked into factory limitations. Swap tubes to match your quarry and distance: tight for distant pheasants, open for jumping grouse in dense cover. The ventilated rib aids sight picture and reduces mirage on warm days, and the front fiber-optic sight gives you a quick, visible reference in low light or fast-moving situations. The automatic extractor handles both 2¾- and 3-inch 20-gauge shells, so you can load whichever round the situation demands without fumbling through a manual operation.
This is an honest, working shotgun built for hunters and shooters who understand that an over-under's ergonomic advantage and crisp trigger break justify the investment. The 20-gauge is no consolation round—it's a deliberate choice for anyone who shoots enough to appreciate the reduced fatigue and cost of running lighter ammunition. Pair it with quality ammunition, master the gun's balance, and you'll find it handles birds and clays with surprising efficiency.
| Gauge | 20 |
| Barrel Length | 28 inches |
| Barrel Configuration | Over-Under |
| Chamber | 2¾" and 3" |
| Receiver Material | Steel, silver finish |
| Stock Material | Turkish Walnut |
| Buttpad | Rubber |
| Front Sight | Fiber Optic |
| Chokes | 5-piece interchangeable set with wrench |
| Extractor | Automatic |
| Rib Type | Ventilated |
The shotgun ships with a five-piece interchangeable choke set and the wrench needed to swap them. You can tailor the constriction to your shooting application—open patterns for close-range upland work or tighter tubes for longer-distance hunting and clay sports—without any gunsmith assistance.
Yes. The SP is chambered for both 2¾-inch and 3-inch 20-gauge rounds. The automatic extractor cycles both lengths, so you can load whichever shell weight and velocity suit your intended quarry or shooting discipline.
The 20-gauge is a purposeful choice for upland bird hunting and clay target shooting. It generates less recoil and cost per shot than 12-gauge, making it ideal for hunters who shoot frequently or prefer lighter swing dynamics—and modern ammunition choices mean you don't sacrifice effective range or knockdown when shot placement is sound.
You receive the Adamson SP over-under shotgun with a five-piece choke set and the dedicated wrench for changing them. The rubber buttpad is factory-installed to help manage recoil.
