The Sig Sauer MCX Rattler CO2 BB air rifle brings the ergonomics and controls of a modern tactical platform down to a fun, backyard-friendly scale. Built on the MCX Rattler design, this semi-automatic airgun runs on CO2 and fires 4.5mm steel BBs at 300 FPS, making it capable enough for target practice, plinking, and training drills without the cost or noise of centerfire shooting. It's a natural pick for shooters who want to practice trigger control and manual of arms in a low-recoil, low-report package—or just enjoy blasting targets in the yard.
The 30-round magazine keeps you downrange longer between reloads, and the semi-automatic trigger breaks cleanly for each shot. Toggle to 3-round burst mode when you want a different training challenge or just want to watch the fun unfold. The M-Lok handguard is fully compatible with standard M-Lok accessories, so you can build it out with lights, lasers, or grips as your training evolves. Flip-up sights come ready to deploy, and the minimalist folding stock keeps the overall profile compact—useful when you're transitioning between drills or storing the rifle in tight quarters.
CO2-powered air rifles are reliable, consistent, and easy to maintain. There's no spring fatigue or cocking effort to manage on every shot. This Rattler is a serious tool for dry-fire discipline, youth shooters stepping into centerfire, or anyone who loves the MCX platform and wants to run it hard without breaking the bank on ammo or dealing with hearing protection in the backyard.

Yes. The semi-automatic trigger and 3-round burst mode allow you to practice trigger discipline, manual of arms, and target transitions at a fraction of the cost and noise of centerfire training. It's popular with shooters who want to refine their technique or introduce new shooters to proper rifle handling.

Yes. The M-Lok handguard is compatible with standard M-Lok accessories, so you can mount lights, lasers, or a scope ring to customize it for your shooting needs.
