  • Product Description

    The conception of the SIG MCX Rattler PSB roots from its parent MCX, but is the shorter, lighter, and more compact version. Originally designed for elite military personnel and sporting a conservative 5.5-inch barrel length, this AR-platform is recognized for its compact stature and ultimate maneuverability. The MCX Rattler PSB is also gaining a reputation for being the ideal compact personal defense weapon and is notorious for its discreet build. Sporting a 3-position collapsing pistol brace also makes for easy compact concealment and is considered a great choice for quick-moving operators. Whatever your needs, this MCX Rattler PSB is sure to have you covered.

    Silencer Shop Note:

    You must select your choice of Sig silencer, SRD762-QD or SRD762Ti-QD, with the Sig MCX Rattler PSB. Rifles will not be sold separately, but you’ll want this dynamic duo anyhow.
