The MCX Rattler Canebrake is the newest addition to the MCX line of firearms. Designed for those to want to run a suppressed setup without purchasing additional components. The Canebrake comes from factory with a 5.5″ barrel and an inert training device, making it operable while waiting for NFA paperwork to clear. The training device has a similar weight to the SRD762 suppressor and can be swapped out for compatible suppressor of your choice. The SD handguard will accomodate suppressors up to 2″ in diameter.
