The MCX Rattler Canebrake is the newest addition to the MCX family. Created for those that desire the MCX as a suppressed system, and eliminates the need to purchase additional components to do so. The Rattler Canebrake comes with a factory installed inert training device, making it operable right out of the box while NFA paperwork and waiting periods are completed, and then is easily convertible to run suppressed.
The MCX Rattler Canebrake 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 assure all muzzle flash is past the shooters hand when reaching out on the handguard during operation without a functional suppressor installed. With the MCX Rattler Canebrake there’s no need for the purchase of a shorter barrel kit and SD Handguard to have a suppressed MCX system, simply unthread the inert training device, install your suppressor, and select the appropriate gas setting for your ammunition.
Additional features of the MCX Rattler Canebrake include a 2-stage flat-blade match trigger, Cerakote E190 finished upper and lower, a folding coyote-tan PCB, and comes with one 30-round polymer 300blk Magpul™ magazine.

Fantastic Firearm Overall. The Pistol Grip That Originally Came With It, Could’ve Been Made Longer IMO. I Changed It To An ATI. Magpul Sights. Davis & Sam In Sig Optics Graciously Helped Me Pick Out The Romeo 4(Solar Edition). Fantastic Customer Service. Skeletonized Forend Grip. Ended Up Going With The Nomad-30 For Suppressor(Still At Local GRead more about review stating Almost Perfect PDWun Range). I Love The Set Up But If I Had To Spend It Again. Out The Gate I Would Personally Go With The SIG VIRTUS TACOPS. Very Similar Features. Comes With A Longer Pistol Grip, Sights & All Black. I’m Still Not Completely Sold On The Brace But I’m Working With It. Thank You Sig For The Constant Engineering Of Fantastic Products!

The canebrake looked to be a new fave as it is very compact and balanced. However, after proper break-in, the accuracy and reliability are horrible. With 2 different cans, subs keyhole at 50y. Groups were abysmal. Initially, saw 4 moa and what looked like 2 moa with supersonics. Then I would have bullets miss the target entirely. I tried 2 differeRead more about review stating Pretty gun, Lousy performancent scopes, 2 different cans, many types of ammo, took off the barrel and re-tightened it to torque specs, and it is pretty much 3″ groups at 25 yards at this point. I had to open the gas port to unsuppressed setting as it failed to lock open with the supersonics. I refuse to run subs at this point as keyholing might damage a can. I wish sig would put a ambi bolt release on the mcx just like the mpx and or spear. Trigger is nice, but needs lighter springs for trigger pull. I’ve heard an occasional owner getting a 1 moa rattler, but honestly I can’t believe a 5.5 inch barrel can possibly stabilize a heavy subsonic safely. I plan to sell this gun.
