The SIG Sauer MCX is a weapon series designed and manufactured by SIG Sauer, featuring a short-stroke gas piston system, carried over from the SIG Sauer MPX submachine gun. It is made in both semi-automatic and selective fire configurations. It comes as a rifle, short barreled rifle, or pistol configuration.
Built at SIG's New Hampshire factory, the MCX was "engineered from the ground up to be short, light and silenced," according to a SIG Sauer brochure.
In 2016, SIG recalled some weapons with the first generation bolt carrier group.
The SIG Sauer MCX series features a short-stroke gas piston system to reduce recoil and improve the reliability of the weapon; this was based on the design of the earlier SIG Sauer MPX. The MCX features a system that allows for conversion between 5.56×45mm NATO, .300 AAC Blackout and 7.62×39mm ammunition, using standard 5.56×45mm STANAG magazines for 5.56×45mm NATO and .300 AAC Blackout, and specially designed STANAG-compatible magazines for 7.62×39mm. The MCX is designed to deliver optimal performance with the .300 AAC Blackout and an optional suppressor.
The barrel's profile is tapered at the crown to allow the installation of muzzle devices and direct-thread sound suppressors without the use of washers that degrade performance and allows the devices to self-center on installation. The barrel can be changed in a matter of seconds to another length or a different caliber. Additionally the barrels are nitride coated for corrosion resistance. It features hardened steel wear points.
