Today, SIG Sauer proudly announced the next generation of the MCX lineup with the new SIG Sauer MCX Spear-LT. The new MCX Spear-LT is an Amalgamation of the original MCX and the MCX Virtus. Taking the best of both iterations of the MCX and combining them together to make the most cohesive rifle experience SIG has ever potentially produced.

The new MCX Spear-LT will be chambered in 5.56, .300 Blackout, and 7.62×39. The Spear-LT is the first MCX chambered in the popular Russian ammo. The MCX Spear-LT will have barrel lengths of 9”, 11.5”, and 16” inches. Also, the new rifle from SIG SAUER will accept all AR-15 triggers as well as all legacy MCX triggers.

Below, is the press release and specs from SIG SAUER on the new SIG MCX Spear-LT.

Press Release

NEWINGTON, N.H., (September 19, 2022) – SIG SAUER is pleased to announce the evolution of the most advanced and tested rifle platform in the world with the introduction of the MCX-SPEAR-LT. Built off the foundation of the MCX Virtus the third generation of the MCX combines all the extensive testing, continued product development, and customer/special operations feedback to become the MCX-SPEAR-LT.

“The first generation of the MCX platform was designed to be an AR-15 style platform with added modularity. The second generation of the MCX, the MCX Virtus, was purpose-built for rugged durability and brought unprecedented modularity. Now comes the MCX-SPEAR-LT, which incorporates the best of both generations and is the culmination of the latest research, development, and innovation in the MCX platform,” said Tom Taylor, Chief Marketing Officer and Executive Vice President, Commercial Sales, SIG SAUER, Inc. “The lightened handguard has the expected rigidity and durability of the MCX, the lower is a familiar SDI, M400-style lower and ambi-bolt catch and release that is designed to fit the legacy VIRTUS uppers for more versatility. The MCX-SPEAR-LT will accept AR-15 style triggers, in addition to the legacy triggers for even more flexibility in the MCX platform. With the MCX-SPEAR_LT also comes the long-awaited addition of the 7.62×39 caliber to the MCX family bringing even more modularity to a platform that simply can’t be matched. The evolution continues and the MCX-SPEAR-LT has raised the bar for modular weapons technology.”

The MCX-SPEAR-LT rifle is an aluminum frame rifle with a gas piston operating system featuring a lightweight ergonomic handguard, push-button folding stock with cheek-rest, and a cold hammer forged carbon steel barrel available in 9-inch (300BLK), 11.5-inch (7.62×39 & 5.56), and 16-inch (7.62×39 & 5.56) lengths. The rifle offers fully ambidextrous controls including bolt catch and release, a SIG QD suppressor-ready flash hider optimized for SIG SAUER QD suppressors, a SIG flatblade match trigger, comes optics ready and can be easily paired with a SIG SAUER Electro-Optics ROMEO8 or TANGO6T, and is finished in a Coyote Anodized finish.
