The Sig Sauer MCX Air Gen 2 CO2 .177 pellet rifle brings modern tactical ergonomics and real shooting performance to airgun enthusiasts who demand accuracy and versatility. Built on the same platform design as Sig's centerfire MCX carbine, this .177 pellet rifle delivers a familiar manual-of-arms for shooters who want to train, compete, or enjoy backyard plinking without centerfire logistics. Powered by CO2 and fed from a 30-round magazine, the Gen 2 MCX Air is purpose-built for shooters serious about repeatability and control.

The 18-inch barrel strikes a practical balance between velocity and handling, while the M-LOK forend lets you customize your setup with rails, lights, and accessories as your needs evolve. A flat-faced trigger and quick-detach stock give you the precision trigger control and adjustability serious shooters expect. The included 1-4x24mm scope mounts directly above the action, providing magnification flexibility for targets from close range to distance, right out of the box.

Whether you're sighting in a new optic before a hunt, running training drills in your yard, or competing in airgun matches, the MCX Air Gen 2 handles like a real rifle while keeping costs and logistics manageable. It's the thinking shooter's airgun—packed with tactical features and engineered to perform with the attention to detail Sig brings to every product.
