The Sig Sauer MCX Rattler is a highly adaptable, versatile and reliable semi-auto pistol. The MPX offers the highest level of operator safety with unmatched in-field adaptability and the reliability you have come to expect from a Sig firearm. It features a Cerakote finished receiver and a 5.5-inch barrel chambered in .300 AAC Blackout. The MCX Rattler comes equipped with the new Sig Sauer Pivoting Contour Brace (PCB) giving pistol users a brace that easily swivels to adapt to the movement of the shooter's arm and can be rapidly deployed. This MCX features a Romeo4T for short and medium range engagements. This optic provides eye relief and easy target acquisition in all scenarios. The Romeo4T offers four different reticle options (Dot, CircleDot, Dot with Holds, and Circledot with Holds). It boasts a strong, lightweight 7075 Aluminum housing and is fog-proof, waterproof and submersible up to 20 meters for optimal durability. The combination of a CR2302 battery, solar power and the MOTAC system the Romeo offers in excess of 100,000 hours of battery usage. The Sig Sauer MCX Rattler with the Romeo4T is a compact and versatile weapon for the operational minded shooter.
