Since 2018, the Super X3 shotgun has been discontinued from manufacture. At first appearance, the Winchester SX3 appears to be simply another attractive auto-loading shotgun. The comb's gentle curvature and the vented rib that contains a single bead at the gun's end may initially catch your eye. For the model with a 28"-barrel length, the weight of the gun is only 7.2 pounds. That suggests that those long treks will be a bit more bearable. An Active Valve system is used in the SX3. This indicates that Winchester has created a universal automatic weapon that can fire both 3.5" magnums and 2 ¾ " 1 oz. bullets. The company advises that the 3.5" versions only shoot 1 1/8 oz. loads, yet it also works quite well with the lighter 1 oz. shells. The gas system adapts to the various types of rounds and ensures that your gun continues to fire until it is empty. Additionally, the gas system reduces perceived recoil. The gun is easy to use. There are no difficult pins and levers to disassemble; it just opens, allowing you to access and clean it with ease. The Super X3 has a striking appearance that goes beyond aesthetics. For a lighter, more controllable feel, the stock, grip, and forearm proportions have all been reduced. A half-pound lighter recoil spring system and lightweight aluminum magazine tube add to the overall feeling of lightness. With a slim profile and a machined rib, the new lightweight barrel eliminates even more weight. The barrel's inside contains .742′′ Back-Bored Technology for the best velocity and accuracy of the shot. The self-adjusting Active Valve assures durability, speed, and reduced recoil under all circumstances. Shotguns made by Winchester Repeating Arms are renowned for being dependable, attractive, and high-performing. Over the years, Super X3 Shotguns have had three different metal finishes: camo dip, Perma-CoteTM UT, and standard blued finish. Numerous versions of the X3 model also differ in barrel lengths and caliber/gauge.
