Since 2015, Sig Sauer has been working on developing the best weapon system on earth. Drawing inspiration from the pillars that build the foundation of the family of modern platforms, the MCX is an ever evolving force to be reckoned with. With features of the classic Stoner and Sullivan Armalite rifles, the AR-15 and AR-18, Sig adds their own years of research and development. With variants serving around the world with military and law enforcement as well as discerning members of the shooting public, the MCX is here to stay. Through continuing innovation, exhaustive testing, and feedback from real world customer and war fighters, Sig has finally launched the third generation of the battle tested MCX series.
The new MCX-Spear LT uses advancements made by the MCX Virtus as well as the new US Army selected M5 SPEAR and takes the next step in the platform's evolution. First, the new handguard system is lighter and more rigid thanks to its new shape and attachment screws to allow for retaining zero on things such as laser aiming units. A lightened barrel contour saves weight and improves accuracy. The already leftie friendly MCX series has become even better with the new ambidextrous bolt catch as found on the M400 SDI. This makes weapon manipulation and malfunction clearance even more natural. The coyote anodized lower has been further improved with the inclusion of Sig's flat blade match trigger, while also now being compatible with most standard AR-15 triggers. Ignition strength has also been increased to add the long awaited 7.62X39 compatibility (conversion parts sold separately) no matter what ammunition you use. The minimalist folding stock and the receiver QD points are strengthened by the use of steel inserts. The included flash hider is ready to accept Sig Sauer QD Clutch-LOK silencers out of the box.
