SIG Sauer launched a new and improved model of its popular MCX platform, called the MCX Virtus, after consulting with numerous special operations groups around the globe to improve the qualities of the firearm.

"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."

The company named the redesigned rifle the Virtus to highlight the values of courage, bravery and exellence, all qualities embodied by the professional operators for which this rifle was built. The upgraded components of the new Virtus are designed to provide users with greater accuracy, longer service life and wider versatility and modularity. The new rifle is designed to give users 20,000 rounds of operation without requiring a single part replacement.

Some of the upgrades to the platform include a heavier-profile barrel that works to improve accuracy potential. The gun also comes with the company's new Matchlite Duo Trigger, which provides users with a two-stage arrangement that still ensures a clean trigger pull. SIG Sauer also improved the design of the bolt lug in order to provide smoother cycling, thereby lengthening the service life of the bolt.

Increased modularity was also an aim of the upgrades, and SIG Sauer delivered with eight different M-Lok handguards that are available in both suppressor-ready and standard arrangements. The company also provides cold-hammer-forged barrels that come in lengths of 9 inches, 11.5 inches and 16 inches. The barrels are easily interchangeable and can be swapped out by the end user.

The SIG Sauer MCX Virtus platform still uses the company's short-stroke piston system, along with the internal recoil arrangement that removes the need for a buffer tube. The platform can be had in Patrol (rifle-length), Pistol and SBR models. Color options are available in either gray or flat dark earth, and available caliber options are 5.56 NATO and .300 BLK. The suggested retail price on the new MCX Virtus starts at $2,233.
