SIG MCX: Background

 

The SIG MCX is a modular and multi-caliber rifle introduced in 2015 by SIG USA, a part of the Swiss company SIG Sauer. It was designed to produce a versatile, easily configurable weapon system that would appeal to various operators for various mission types.

The design focused, we’re told, on compact geometry and reduced weight to make it more suitable for confined space work and urban operations. That’s what we’ve read anyway, and it makes sense.

Did they achieve that goal? Yeah, it seems like they have. The MCX family of weapons is popular not just with specialized military/LE units, but with civilian shooters too.

The MCX’s modular design has been one of its major selling points since the git-go. Even in a market full of customizable weapon platforms, the MCX stands out for its ease of individualization. For instance, the upper receiver can be quickly swapped out to change the caliber, barrel length, and other features.

The lower receiver is a little less striking, though much like its AR-platform cousins, it can be fitted with a slew of different stocks, grips, and accessories.

As for what to feed it and how to use it, models of the MCX are available in several calibers, including (but not limited to): 

 

5.56mm NATO

300 AAC Blackout

7.62x39mm

.277 Fury

6.5 Creedmoor

 

Short-Stroking It

The MCX isn’t a direct-impingement gun like your typical black rifle. Instead, it uses a short-stroke piston gas system. This (among other things) helps SIG keep the size small, making the MCX more suitable for close-quarters work than some of its competitors.

SIG MCX Models

 

There are several versions of the MCX available, some select-fire, some semi-auto only, and in pistol/SBR, carbine, and rifle configurations. These include (but aren’t limited to) the…

 

1. SIG MCX Virtus: The Virtus was the second generation MCX, introduced in 2017. The Virtus is available in several configurations and is designed for use by military and law enforcement personnel. It features an improved trigger, a new handguard, and a longer barrel.

2. SIG MCX Rattler: The Rattler is a compact, SBR version of the SIG MCX designed for Personal Defense Weapon (PDW) use. It features a 5.5-inch barrel and a folding stock, making it highly portable. The Rattler won the USSOCOM Commercial Personal Defense Weapon (CPDW) contract and will reportedly be utilized in suppressed .300 BLK and 5.56mm NATO configurations. 

3. SIG MCX Patrol: The Patrol is a civilian version of the SIG MCX. It features a 16-inch barrel and a fixed stock, making it suitable for various applications.

4. SIG MCX SBR: The SBR (Short Barreled Rifle) is a variant of the SIG MCX that is designed for use by military and law enforcement personnel, though it could be utilized by civilians who follow NFA dictates. It sports a 9-inch barrel and a folding stock for improved portability. The MCX SBRhas a cousin called the Low Visibility Assault Weapon (LVAW) that is both suppressed and select-fire. 

5. SIG MCX-SPEAR: The SPEAR was SIG’s admission to the US Army’s Next Generation Squad Weapon program. It is chambered in SIG’s proprietary 6.8×51 SIG Fury cartridge. 

6. SIG MCX Canebrake: The Canebrake is a special SIG MCX edition designed specifically for use as a suppressed system.

MCX in the Field and Overseas

 

In addition to units of the United States Army, the SIG MCX is used by the security forces of several allied nations, including: 

  • The French Army: The French Army’s Special Forces and Rapid Reaction Corps have adopted the SIG MCX to replace the FAMAS assault rifle.
  • German Police Units: Some German police agencies have adopted the SIG MCX for use by their tactical units.
  • Finnish Army: The Finnish Army has reportedly adopted the SIG MCX to replace their aging RK 62 assault rifles.
  • Norwegian Police: The Norwegian police have also reportedly adopted the SIG MCX for use by their tactical units.
  • Israeli SOF: At least some elements of the IDF SOF stable have reportedly begun using the SIG MCX in lieu of their M4s. 
  • Danish police: As with Norway and Germany, some law enforcement agencies in Denmark are now using the MCX.
