Item # 293820 Style AIR-RATTLER-BB UPC 798681604234 Condition New Manufacturer [Sig Sauer](https://www.kygunco.com/brand/sig-sauer) Designed to mirror the look and feel of its 300 Blackout counterpart, the MCX Rattler air rifle delivers an authentic shooting experience with exceptional attention to detail. Load up the full-size magazine, rack the charging handle, and switch the ambidextrous fire selector to burst mode—each trigger pull sends a precise three-round burst downrange. Thanks to its internal blowback system, you'll feel a realistic recoil impulse with every shot. When the magazine runs empty, the bolt locks back, prompting a true-to-life reload using either the bolt release or charging handle. Whether you're training or just plinking in the backyard, the SIG SAUER Rattler BB rifle offers unmatched realism and performance. FEATURES - Selectable semi-auto and 3-round burst firing modes - Internal blowback action for realistic recoil - Functional charging handle and bolt catch for authentic reload drills - Ambidextrous fire selector and magazine release - Full-size 30-round magazine with integrated 12g CO2 cartridge - M-LOK accessory rail and full-length Picatinny optics mount - Fully adjustable flip-up sights ** WARNING: This product contains chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm.
