The SIG MCX is a carbine series designed and manufactured by SIG Sauer, featuring a short-stroke gas piston system, carried over from the SIG MPX submachine gun. It is made in both semi-automatic and selective fire (assault rifle) configurations. Sig Sauer (USA) Advertises the MCX line as being modular, light, and short. It also advertises the MCX line as being "the first rifle built to be silenced from the ground up"[3] The MCX line shares many of the features of the AR-15, and it is compatible with mil-spec AR-15 lowers, but, unlike the AR-15, it does not require a buffer tube, allowing it to be shorter in length, and also allowing it to use side-folding stocks.[4]

Design

The SIG MCX series features a short-stroke gas piston system to reduce recoil and improve the reliability of the weapon. 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.[5][6][7] The MCX is designed to deliver optimal performance with the .300 AAC Blackout and an optional suppressor.[4]

Variants

  • MCX Carbine: Carbine, with 16 inches (410 mm) barrel. Available with a safe/semi-automatic trigger group for U.S. civilian sales, or safe/semi-automatic/fully-automatic trigger group for law enforcement and military sales.
  • MCX SBR: Short-barreled rifle, with 9 inches (230 mm) barrel. Available with a safe/semi-automatic trigger group for U.S. civilian sales, or safe/semi-automatic/fully-automatic trigger group for law enforcement and military sales. Under U.S. federal law, rifles with barrels shorter than 16 inches are Title II weapons, which are subject to federal restrictions, as well as being regulated by state laws.
  • MCX Pistol w/ SBX: Semi-automatic pistol, with 9 inches (230 mm) barrel, SIG SBX stabilizing brace and safe/semi-automatic trigger group. This version fits the U.S. legal definition of a "handgun", in that it is only designed to be fired with a single point of contact with the shooter's body,[8] though in general terms, it is a compact carbine rifle, as it fires an intermediate round. The BATFE has warned users that shouldering a weapon fitted with the SIG SBX or a similar forearm brace, and not registered as a short-barreled rifle, constitutes the making of a short-barreled rifle, which is a Title II weapon.[9]
  • MCX Low Visibility Assault Weapon (LVAW): Short-barreled, suppressed, select-fire variant available only to law enforcement and the military. It is nicknamed "Black Mamba".[10][11]
