The ATI Cavalry GKOF12SV is a 12-gauge over/under shotgun built for hunters and sport shooters who value reliability and versatility in a classic break-action platform. With a 28-inch barrel, dual triggers, and a receiver engraved with quality detail, this O/U delivers the handling balance and sight picture serious upland, waterfowl, and clay shooters expect—without unnecessary frills or premium pricing that doesn't add function.

Built on a steel receiver and fitted with 4140 chrome-moly barrels (chrome-plated inside and out for corrosion resistance), the Cavalry is engineered to handle 3-inch 12-gauge loads. The single selective trigger lets you choose which barrel fires first, a practical advantage in the field or on the range. Walnut furniture with an oil finish gives the shotgun a traditional, hand-finished appearance that ages well and feels good in your hands. At 5.9 pounds, it's light enough for a day afield without fatigue, yet substantial enough for smooth swing and follow-through.

The 28-inch barrels come fitted with five interchangeable choke tubes—Cylinder, Improved Cylinder, Modified, Improved Modified, and Full—so you can dial in the right constriction for your distance and quarry. The brass bead front sight is simple, reliable, and fast to pick up, whether you're pointing at a flushing bird or swinging on a clay target. An extractor (rather than ejector) mechanism keeps operation straightforward and cost-effective. This is a workhorse shotgun: honest engineering, forgiving ergonomics, and proven break-action design that hunters have trusted for generations.

Frequently Asked Questions

What choke tubes come with the ATI Cavalry GKOF12SV?

This shotgun includes five interchangeable choke tubes: Cylinder (no constriction), Improved Cylinder, Modified, Improved Modified, and Full. You can swap them to match your shooting distance and game—tight patterns for distant targets, open patterns for closer work.

Can this shotgun handle 3-inch magnum loads?

Yes. The Cavalry has a 3-inch chamber, so it will safely fire both standard 2.75-inch and 3-inch 12-gauge ammunition, giving you flexibility in load selection for upland birds, waterfowl, and clay shooting.

What's the difference between an extractor and an ejector?

An extractor simply withdraws spent shells partway out of the chamber when you open the action, allowing you to remove them by hand. An ejector throws them clear automatically. Extractors are simpler, require less maintenance, and are easier to clean around—a practical choice for field use.

Is the Cavalry suitable for clay target shooting?

Yes. The balanced 28-inch barrels, interchangeable chokes, and reliable single selective trigger make it well-suited for trap, skeet, and sporting clays. The walnut furniture and traditional profile also appeal to shooters who appreciate classic shotgun handling.
