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: http://www.sigsauer.com/TeamSig/Sweepstakes.aspx
