The SIG SAUER MCX in its SBR configuration represents the modern piston carbine done right — the same platform family trusted by military and law enforcement units around the world. This version pairs a 14.5-inch 5.56mm barrel with a black finish, running SIG's short-stroke gas piston system that stays cleaner and cooler than direct impingement and shines when suppressed. With its internal recoil system, the MCX needs no buffer tube, enabling folding stocks and a genuinely compact footprint for vehicle or home defense roles. This is an NFA short-barreled rifle; our team will guide you through the transfer process.
