SIG MCX Rattler Canebrake: It’s Suppressor Ready! – SHOT Show 2019

The “inert training device” allows you to shoot the gun before your tax stamp arrives.

SIG’s new MCX Rattler Canebrake, so named because it’s the smallest of their Rattler family, is the suppressor-ready version of the MCX. Its 5.5-inch barrel comes with a place-holder on the end so that you can shoot it right out of the box, even if your suppressor stamp is held up by a government shutdown.

The “inert training device” on the end won’t suppress the report, but it will allow you to hold the SD handguard while shooting without being burned by the flash.

The Canebrake’s 5.5-inch barrel ends well inside the SD handguard–don’t shoot it without a suppressor or the inert training device!

The Canebrake features SIG’s PCB folding brace to make it compact. The back of the brace straps to your arm and pivots with you for comfort and stability. The straps tuck away inside the collapsed brace so nothing snags when deployed.

The Canebrake is chambered for .300 Blackout and 5.56 NATO and finished in either hard coat anodized black or Cerakote E190 with black details. It’s just 6.6 lbs and is 29.5″ with the brace open.

    I just purchased an MCX rattler, and it seems that Sig is always improving each firearm it produces. Does Sig think about people who bought previous editions that can upgrade their versions to the newest versions. I am going to suppress mine for eventually for the simple fact I have hearing damage already.

    Using that “Pistol Brace” as a stock just put you into the ATF bizarro world of converting that pistol into an SBR….

    Also, where the hell is Clay, he is much much better at this!

      Not True. You can shoulder a pistol brace. ATF has ruled.

      Yea dude that’s wholly incorrect on every aspect you can be incorrect on in this discussion. Read the ATF letter regarding a brace & firing positions. May help.
