The Sig Sauer® MCX Virtus® Patrol Semi-Auto Rifle has quietly made it's way into the hands of top tier military units, which is understandable with its all-around solid-quality construction and features that solve almost any problem you could put before it. The top rail features an often overlooked, monolithic extension design, ensuring any quality sighting accessories attached will remain zeroed. The ambidextrous controls make the MCX platform easy to use for anyone. The MCX features a full-length M-LOK® rail, a folding and collapsible stock, and an AR-15 pattern grip. Sig Sauer's gas-operated, short-stroke piston system pulls off extreme reliability, giving you a boost of confidence in the field. The piston and piston channel should be kept dry and the MCX will simply keep running for you. The MCX has been one of few rifles to stand against the AR-15 platform and gain wide acceptance.
