SIG SAUER® MCX® Rattler Canebrake .300 AAC Blackout Semi-auto AR Pistol

Rapid deployment, agility and precision: this is the SIG MCX. Built around a cool, clean gas piston system, PDW upper, and 5.5" barrel, the MCX platform has never been more compact or versatile. Ready to go wherever it's needed, the MCX Rattler features a side-folding pistol brace for stability and easy concealment.

The MCX Rattler Canebrake model comes as a suppressor-ready platform with an SD handguard and inert training device that mimics the size and weight of the SIGSRD762 suppressor—and assures all muzzle flash is past the shooter's hand during operation. It's ready to go right out of the box while NFA paperwork and waiting periods are completed. When you're ready for a real suppressor, simply thread the inert training device, install your suppressor, and select the appropriate gas setting for your ammo. No need to purchase an SBR kit.

Additional features of the MCX Rattler Canebrake include a 2-stage flat-blade match trigger, Cerakote E190 finished upper and lower, and folding coyote-tan PCB.

  • Comes with an "inert training device" (or faux suppressor) that mimics the size and weight of the SIGSRD762 suppressor
  • When it's time to install a real suppressor, simply unscrew the inert training device and change the gas setting
  • Suppressor-ready M-LOK handguard
  • 2-stage Matchlite Duo flat-blade trigger
  • Gas piston operating system runs cooler and cleaner than standard direct impingement
  • Built on a PDW (Personal Defense Weapon) upper receiver and 5.5" barrel
  • Cerakote E190 finished upper and lower
  • SIG PCB side-folding fixed brace for easy storage in a backpack, truck, etc.
  • Includes (1) 30-rd. magazine
    PLEASE NOTE: Because the barrel is flush with the handguard, shooting the MCX Rattler Canebrake without the inert training device is not advisable.
