Condition: New Old Stock - unfired, taken off
This listing is for a complete factory SIG MCX Rattler Canebrake upper in .300 AAC Blackout — an increasingly hard-to-find upper assembly that has become highly sought after since SIG Sauer officially discontinued the Canebrake model.
The Canebrake was designed to emulate the ideal suppressed .300 BLK PDW setup. SIG factory-tuned the gas system specifically for suppressed supersonic and subsonic use, making this upper the perfect base for suppressed, short-barrel builds.
This is not a firearm and ships directly to the buyer. Must comply with NFA laws if used in an SBR configuration. Always check your state and federal regulations.
