<p>The SIG SAUER® MCX-Spear .308 Win./7.62 NATO Semi-Auto AR-10 Pistol is the civilian version of the U.S. Army's new XM7 rifle, delivering military-grade performance to every shooter. It's built around SIG's short-stroke gas piston operating system, which runs cooler and cleaner than the traditional direct impingement system found on most AR-15 and AR-10 rifles. It's equipped with fully ambidextrous controls, catering to both left- and right-handed shooters and ensuring seamless operation and fast access to all critical functions in the field. Like the XM7, the MCX-Spear features an interchangeable barrel for simple caliber conversions. It comes with a 13 barrel topped with a QD suppressor-ready flash hider. The 2-stage match trigger provides a substantially better trigger pull than mil-spec, and the non-reciprocating side and rear charging handles provide maximum flexibility in any shooting position. Integrated steel QD mounts for easy sling attachment. Coyote anodized finish. Rear Picatinny rail for attaching a brace. Includes one 20-round magazine.</p> <ul> <li>Civilian version of the U.S. Army's XM7</li> <li>Short-stroke gas piston operating system</li> <li>Fully ambidextrous controls</li> <li>Interchangeable barrel system</li> <li>13 barrel with QD suppressor-ready flash hider</li> <li>2-stage match trigger</li> <li>M-LOK® handguard</li> <li>Coyote Tan anodized finish</li> </ul>
