SIG is now shipping the MCX in 5.56mm for those of you that have been patiently waiting. I do appreciate that manufacturers are efforting out platforms that allow for reconfiguration with other components that you may have, and the MCX (obviously not the 5.56) that I got to fondle at BMC Tactical was exceptionally nice. Of course this could be to get the MCX in the hands of people that are not fanboys of 300BLK.

In today’s world, being able to reconfigure your rifle for your mission set is very important. Even while in the field, you can configure the SIG MCX as needs or conditions change. SIG SAUER’s Robby Johnson shows how the SIG MCX is redefining adaptability with features like backwards compatibility with any mil-spec AR lower, multiple stock assembly options, and more, enabling you to build a complete weapon system for any scenario or environment.

They are also doing a giveaway for one (that ends on the 30th of September). You can enter to win at:

    Looks nice and all but I don't trust SIG-USA when it comes to rifles. What happened to the SIG 556 XI again? The last time that I remember it was when I saw a video review where 556 XI failed miserably in term of reliability when compare to the Galil ACE.. It looks like SIG is 'quietly' abandoning it now.

    Also, the fact that SIG quickly rushed out the "Gen 2" version with an adjustable gas regulator show just how incompetence they are. It gives me the impression that they didn't fully tested their product BEFORE mass producing and releasing it.

    And last but not least, Larry Vickers isn't too fond of the MCX, either.

      @NewMan I see. I disagree with him on the concept of pistons not being a good idea in short barrels. Adams Arms has done well with pistons on 7.5" ARs. I suspect there were different issues with the 416 project. SIG is designing this from the ground up, not trying to fit a current system into a smaller package. I have a feeling it will turn out better than he expects.

      All the gas systems look to be the same length regardless of barrel length in this system so far. We'll see how it goes. I'll have my MCX in my hands in a couple of weeks, once I free it.

      We'll see.

    Sig has been having a lot of roll out problems. The MPX for example. No stocks available, magazines are few and far between. All SIG says is their coming...

    If you need to buy additional parts from SIG to reconfigure your MCX, you better have a back up plan imo.
