The Adamson Xdefense Rx is a 12-gauge semi-automatic shotgun built for home defense with a no-nonsense 18.5-inch barrel and tactical features that mean business. This is a modern, duty-ready shotgun that combines aggressive styling with practical ergonomics—the kind of firearm that works whether you're securing your property or training at the range. With its skeleton pistol grip stock, extended controls, and Picatinny rail system, the Xdefense Rx gives you a platform that's ready for lights, lasers, or other accessories from day one.
The receiver showcases Adamson's new design with distinctive red-line accents, and the ported barrel helps manage recoil and muzzle rise—especially useful in defensive scenarios where follow-up shots matter. Fast-loading capability, an extended bolt handle and release button, and a ghost front sight keep the manual of arms straightforward and intuitive. The gun ships with a five-piece choke set and wrench, so you can tune the pattern to your needs whether you're running buckshot or slugs.
This 3-inch magnum chamber accepts a variety of ammunition, and the 5+1 magazine capacity gives you six rounds ready to go. The rubber butt plate helps tame felt recoil, and the overall design emphasizes speed and reliability over unnecessary complexity. If you're looking for a semi-auto 12-gauge that prioritizes function and doesn't apologize for its tactical DNA, the Xdefense Rx delivers the goods at a straightforward value.
