The Sig Sauer MCX Rattler Canebrake PDW is the company’s most recent addition to their suppressor ready pistol platform. The gun is built around a 5.5” 300 blackout barrel with an adjustable short-stroke gas piston system. This enables the gun to be used with or without an aftermarket suppressor. The Canebrake is also compatible with many AR pattern accessories making it a true pistol-caliber carbine.
The Canebrake features a quick-detach m-lok handguard that locks into place with two grooves cut into the sides of the upper and a lug captured by a takedown pin at the front. The handguard is also large enough to accept a silencer if desired. Sig also includes a 2 stage match grade flat blade trigger with a light crisp break that aids in tack driving accuracy. A Coyote Tan Cerakote finish on the upper and lower adds to the tactical look of the gun.
This gun has a pistol grip that is comfortable and grippy. It is compact and looks like something a bodyguard in a movie would use to take out bad guys. It has a retractable brace on the left side that can be rapidly deployed by pushing up against it with your thumb. This allows you to get back into the pistol grip and re-engage with the target quickly.
The Canebrake’s rotary magazine release is easy to use and has a definite mechanical advantage over the traditional bolt-action style of many other airguns. HAM testing demonstrates that the Canebrake can achieve 721 FPS peak muzzle velocity with a variety of pellets, but even this is not quite enough power for real-world hunting unless it’s just plinking at soda cans.
