The Rock Island X4 12ga semi-auto shotgun is a gas-operated workhorse built for hunters, sport shooters, and anyone who needs a reliable 12-gauge for defense or field use. With a lightweight aluminum receiver, polymer furniture, and a 4+1 round capacity, the X4 balances practicality with durability—it points naturally, cycles smoothly, and won't punish your shoulder with unnecessary weight. Whether you're running clays, working birds, or keeping one handy for home defense, this platform accepts both 2¾" and 3" shotshells without fussing, so you're never locked into one load.
The 18.5" barrel comes equipped with a vent rib and interchangeable choke tubes (Full, Modified, and Improved Cylinder), giving you the flexibility to dial in your pattern for different hunting scenarios or shooting disciplines. The fiber optic front sight and adjustable open rear sight are straightforward aiming tools—no unnecessary electronics, no complications. At just 7 lbs and 39.37" overall length, the X4 is compact enough for vehicle storage or tight hunting blinds but long enough to swing naturally in the field. The black anodized receiver and polymer furniture shed weather and stand up to regular use without flinching.
This is semi-auto shotgun design stripped down to what matters: proven gas-operated reliability, intuitive controls, and the kind of straightforward performance that builds trust. If you're shopping for a no-frills 12-gauge that works in the real world—not the marketing world—the Rock Island X4 delivers.
