New: SIG MCX Spear LT Family in 7.62x39, 5.56 & 300BLK
The new SIG SauerMCX Spear LT series combines the best of the old Gen 1 MCX with the MCX Virtus and adds more caliber options.
Back from the 1st generation of MCX rifles is the compatibility with standard AR trigger packs-- opening a world of modularity that was lost with the Virtus-- while also slimming the rifle down. Available in 5.56 NATO, .300 Blackout and 7.62x39-- new for the platform and a caliber unusual altogether for SIG, the Spear LT series also comes standard with SIG's SLX QD muzzle device/suppressor mount pre-installed while a redesigned handguard and other tweaks drop almost a pound in weight when compared to the Virtus.
Further, it now comes with an easier-to-operate side folding stock with a push-button release and an ambi bolt catch/release. Other standard features across the line include a Coyote (FDE) finish, a Nitrided barrel, fully ambi controls, and a flat blade match trigger.
SIG has the MCX Spear LT in eight different models on the schedule for this year. The standard carbine, available in 5.56 NATO and 7.62x39, runs about 7.5 pounds with a 16-inch barrel inside a 13-inch lightweight ergonomic handguard and has an overall length when folded of just 21.3 inches (34.3 inches with the stock extended).
For those who like a short game, the MCX Spear LT will be offered in a pistol variant using 9-inch (.300BLK) or 11.5-inch barrels (5.56 NATO and 7.62x39) inside an 8- or 10-inch handguard, respectively. Each will have a short Pic rail on the rear of the receiver.
In factory SBRs, the company has a 9-inch .300BLK and 11.5-inch 5.56 and 7.62x39 complete with the factory-installed folding stock. Want to change out the barrel later, no problem, as they are interchangeable.
Guns.com spoke to Patrick Hanley, SIG Sauer Product Manager, Rifles, about the MCX program last month on a visit to New Hampshire.
"The MCX has been a platform that we've had roughly for almost a decade," said Hanley. "We had customers asking for some of the changes that were partially from the first generation, being the lightweight version of the gun, as well as some of the other feature sets that it had like the AR trigger compatibility that they wanted to see carry over. So, we took the Virtus and all the best features of it and we said, 'How do we bring that back down to weight? How do we bring that feature set back to where we want it?' and that's why we are here today."
