SIG SAUER Introduces MCX VIRTUS

Advanced Modularity and Design Results in More than 500 Configurations

Newington, N.H. (July 3 2017) – SIG SAUER, Inc., The Complete Systems Provider™, unveils the MCX VIRTUS in 5.56 NATO and 300 BLK, a platform engineered and built to be the most adaptive, accurate and longest-lasting rifle available.

The original SIG MCX rifle, conceived for the demands of the Special Operations community, quickly became known in the firearms world because of its durable performance and end-user configurability. To enhance the design, SIG received feedback from Special Operations units throughout the world and made the most advanced rifle ever built, even better. The result is the MCX VIRTUS.

“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. Between barrels, stocks, handguards and colors, the MCX VIRTUS can be configured over 500 different ways for any possible need or mission.

Available in Patrol, 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.

Built by SIG for professionals and shooters of any level, the MCX VIRTUS is ready for any mission.

    How long will it be before SIG USA drops support for this series of guns??

      Right after I buy one, I’m the kiss of death for obsoletion.

      I’ll do everyone a favor and not buy one.

      Sig’s inability to provide continued support for a platform is by far and away the biggest problem with the MCX. On the market for short time and they are already on Gen 3(gen 4 if you consider post recall guns a new generation). The suppressor hand guards for the legacy guns just shipped in the last couple months and they are already showing a new model that is not compatible with them. Are customers expected to wait another year and a half for virtus accessories to ship?

      I do think it is a good upgrade but Sig needs to manage their product lines better. Maybe if they stopped making 3 dozen flavors of p238 pistols they could get it right.

        Well, it doesn’t help that the guy that fucked up Kimber is now fucking up Sig….

    I’m still waiting for a chart or something showing me the differences between this a standard MCX.

    • KDC says:

      Sig rep mentioned on IG.. the gun has different upper, gas system, handguard, trigger, valve and charging handle

    • Rob says:

      Mlok

      Heavier taper profile barrel

      Grey finish

      Different receiver hand guard interface resulting in greater versatility in regard to barrel length and gas system length. (hand guards are not cross compatible with legacy models)

      New Upper receiver that is beefier.

      Longer rail on patrol models

      Ships with 2 stage trigger

      102.00 dollar MSRP price increase.

      An over the top marketing campaign

      Other changes such as the folding/tele stock and the new charging handle are shipping on the legacy MCX as well.

      Overall I would say that the juice is worth the squeeze considering the modest price increase. I doubt that the legacy MCX will be offered for much longer in its current form. The shorter upper receiver rail will allow for a shorter hand guard to will meet the OAL requirement in the recent USSOCOM PDW RFP.

    Appart from the color, what actually changed?

    • EzGoingKev says:

      Per the article the barrel profile is heavier and a different trigger.

      • Jeff says:

        MLOK, Access to the gas block without removing the handguard, trigger is for the recall I assume, and dropping the skeleton stock. Oh, and a price bump…

        • EzGoingKev says:

          I forgot about the MLOK.

          I figure it is only a matter of time and they will offer both options across the board.

          • HSR47 says:

            Keymod is a legacy product; It exists in quantity in the wild, so people are likely to continue making accessories for it, but I’m betting that manufacturers will cease production of keymod handguards in favor of m-lok: m-lok is better for everyone. For manufacturers, it’s cheaper and easier to make right (and cheaper to QC), and it seems to work marginally better than keymod.

    Surprised this isn’t a special for their legion series

  5. PTMcCain says:

    Do they not realize how laughably idiotic it sounds when they make outrageous claims like this:

    “a platform engineered and built to be the most adaptive, accurate and longest-lasting rifle available.”

    Guess not.

  6. Cool Arrow Kicker says:

    It’s funny because two (2) years ago when I had one of the MCXs from Cabela’s there were several delays on barrels, hand guards, stocks and the AR lower adaptor.

    In addition, I was informed that there were some engineering changes in the works, specifically in regards to the upper receiver group’s geometry to allow it to be more “flush” with the M4 lower when used with the adaptor kit.

    When I asked Sig if there were any plans to change the MCX that wouldn’t be reverse compatible with the current rifle I was told that there wasn’t.

    So, I find it humorous that here we are, a little over two (2) years from that correspondence and Sig has announced an improved MCX, which for the most part appears to NOT be compatible with the original system and also incorporates physical changes to the upper and it’s internals.

    While I understand that these changes were undertaken based on observations and feedback from evaluations, it does leave a sour taste in the consumer’s mouth as it appears they were duped into being a beta tester at their own expense for Sig.

    It seems that the lack of configuration management and engineering has placed this rifle on the same track as the ACR.

    It’s a great platform, but at some point the design needs to be finalized and if any changes are to be incorporated, they need to be reverse compatible.

    • Brad says:

      Agreed… that is the one thing keeping me from buying one. With sig, you gotta buy it all at once (you never know when they’ll discontinue accessories) and never be an early adopter… let others be the Guinea pigs….
