Based on feedback from Special Operations unites worldwide, SIG Sauer has enhanced its original MCX adaptive rifle to create the MCX VIRTUS in 5.56 NATO and 300 BLK. With the rifle’s ability to be configured more than 500 ways with options for different barrels, stocks, handguards and colors, SIG is calling it “The Complete Systems Provider.”

"SIG has supplied firearms to meet the unique demands of specialized units for decades," said Ron Cohen, President and CEO of SIG Sauer. "Similar to the P320 pistol, the MCX VIRTUS was created to be the ultimate modular platform, a design that will change the demands of the modern rifle for years to come."

In ancient Rome, "Virtus" stood for virtue, courage, bravery and excellence. The MCX VIRTUS embodies the spirit of the professional users who have depended on and continue to rely on the MCX in the field. The added features and enhancements of the MCX VIRTUS include increasing accuracy, delivering additional modularity and providing a service life of more than 20,000 rounds, all without a single part replacement.

Available in Patrol (shown), Pistol and SBR variants, in Stealth Gray or FDE color, the MCX VIRTUS utilizes the proven SIG Sauer short-stroke piston system and unique internal recoil system that eliminates the M4-style buffer tube. The result is a compact, light-recoiling platform that can be configured for any task.

Cold-hammer-forged barrels, available in 9", 11.5" and 16" lengths, feature an advanced interchangeable design and can be exchanged at the operator level. To increase accuracy, the barrels are of a heavier contour profile. Also assisting with accuracy is the new SIG Matchlite Duo trigger, a two-stage unit that provides the shooter with a crisp, clean feel. A new tapered bolt lug design results in smoother cycling and extends the bolt life. Capping off the upgrades are eight (8) new free-floating M-LOK handguards available in standard and suppressor-ready configurations.
