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:
