The SIG SAUER MCX has become the modern standard for a piston-driven fighting carbine — adopted in various forms by military and law enforcement units worldwide — and this SBR configuration delivers it in its most capable form. The 14.5-inch barrel in 5.56mm preserves nearly full rifle ballistics while the short-stroke gas piston system runs cleaner and cooler than direct impingement, especially suppressed. Finished in FDE, the MCX's folding-stock-capable recoil system needs no buffer tube, keeping the package remarkably compact. This is an NFA short-barreled rifle; we'll guide you through the transfer and paperwork.
