The Virtus is equipped with a heavier barrel in order to enhance accuracy and durability. Accuracy and precision are also enhanced through the inclusion of the company's all-new Matchlite Duo trigger, a two-stage design that offers a crisp pull. The bolt itself also underwent a redesign in order to diminish wear and lengthen service life.
The already-modular MCX became even more modular with the Virtus upgrade, allowing consumers to choose between eight separate M-Lok handguard arrangements. Different-length barrels are also available and are designed to be easily interchangeable by owners.
