Description
The Sig Sauer Airguns MCX Rattler BB brings the look and handling of Sig Sauer’s MCX Rattler SBR to the CO2-powered airgun world. Chambered in 4.5mm steel BB and fed from a full-size 30-round magazine, this BB rifle replicates the controls and overall footprint of the centerfire platform it mirrors.
Built around a 5.5-inch smoothbore barrel, the Rattler BB sends 4.5mm steel BBs downrange at velocities up to 300 fps. The action runs in both semi-auto and full-auto with a selectable 3-round burst mode, giving shooters the chance to stretch the trigger without dumping an entire magazine in a single pull.
Up front, an M-LOK handguard allows mounting of accessories, while flip-up front and rear sights come standard for quick target acquisition. A folding minimalist stock tucks neatly against the receiver for compact transport and storage. At 4.60 lbs, the MCX Rattler BB balances well in the hands.
