Experience the intensity of realistic plinking and tactical training with the SIG SAUER MCX Rattler CO2 BB Air Rifle. Featuring authentic MCX styling including a compact folding minimalist stock, M-LOK handguard, and full-length Picatinny rail this .177 caliber rifle delivers up to 300 FPS with steel BBs. Its single 12-gram CO2 cartridge powers both semi-auto and 3-round burst fire modes, all enhanced by internal blowback for a lifelike recoil impulse.

Accurate Replica of the MCX SBR Platform

Built to mirror the firearm version, the MCX Rattler sports an ambidextrous selector, bolt catch, and charging handle. Its functional bolt lock-back after magazine depletion and textured AR-style pistol grip bring realism and immersion to every shooting session.

Quick-Fire Capability with Selective Fire Modes

Switch between semi-automatic and 3-round burst firing with the ambidextrous selector. The 30-round drop-free magazine integrates a 12g CO2 cartridge and feeds steel BBs for sustained shooting without interruption.

Accessory-Ready and Sighted

Mount optics on the full-length Picatinny rail and use M-LOK slots on the handguard for tactical add-ons like lights or lasers. Adjustable flip-up front and rear sights are included for precise, zeroed shooting right out of the box.

Compact & Practical Design

Measuring 23.6" overall with the stock extended (or folded for storage), this rifle weighs approximately 4.6 lbs ideal for transport or field use. CO2 allows for around 60 shots per cartridge, while blowback realism makes reloading as authentic as possible.

Fun for Plinking & Training

Clocking in at up to 300 FPS and delivering solid accuracy, the MCX Rattler is perfect for target practice, backyard shooting, or tactical drills.
