The Sig Sauer MCX Rattler Canebrake in 300 Blackout 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.

CYCLE OF FUNCTION
There are eight steps in the cycle of function of the SIG MCX which begin after a loaded magazine is inserted into the firearm.
FEEDING
As the bolt carrier is released from its rearward position, the carrier group moves forward allowing the lower lugs of the bolt to make contact with the rear of the cartridge as it sits in the magazine. The cartridge is stripped from the magazine and begins its forward movement toward the chamber.
CHAMBERING
As the bolt moves forward, the bolt locking lugs move forward into the barrel extension. The ejector is then compressed against the left side of the cartridge head. The last action that occurs is the extractor snapping over the rim of the cartridge case.
LOCKING
The movement of the bolt and the cartridge is stopped by the chamber. The bolt carrier continues to move forward until it is stopped by contact with the rear face of the barrel extension. As the carrier goes through the last portion of movement, the bolt is rotated to the left, through the action of the cam slot in the carrier and the cam pin through the bolt. This engages the bolt lugs with the barrel extension lugs to lock the bolt into the barrel extension.
FIRING
The selector is rotated to the Semi position. The trigger is pressed and the hammer is released. The hammer spring drives the hammer forward unlocking the firing pin. The firing pin strikes the cartridge primer,causing detonation.
UNLOCKING
As the bullet passes the gas port in the barrel, a small amount of gas is bled off, traveling up though the gas port and into the gas block. The gas is regulated by the gas valve and is based on the type of ammunition being fired. This gas acts upon the piston to move the operating rod to the rear. The operating rod transfers its energy to the carrier assembly setting it in motion. The rearward movement of the carrier causes the bolt cam pin to rotate the bolt to the unlocked position.
EXTRACTION
As the bolt carrier assembly moves rearward the spent case is pulled free from the chamber by the extractor. The twisting motion of the bolt aids in the extraction from the chamber.
EJECTION
The extractor continues to grip the rim of the spent case on the right side. The ejector is applying forward pressure to the left side of the case. As the expended case clears the chamber, then the barrel extension, it is flipped out through the ejector port on the right side of the receiver.
COCKING
The rearward movement of the bolt carrier overrides the hammer, forcing it down into the receiver and compressing the hammer spring, cocking the hammer in the firing position.
SELECTING MODES OF FIRE
The SIG MCX is available in two fire control configurations. SAFE-SEMI and SAFE-SEMI-AUTO. Modes of fire are selected by rotating the selector lever to the desired position. The SAFE position prevents the firearm from firing by blocking the action of the trigger. The SEMI position is for the semi-automatic mode and allows the firing of one round each time the trigger is depressed. AUTO, if so equipped, allows for a continuous rate of fire until the trigger is released by the operator, or the magazine is depleted of ammunition.
