The SIG MCX is a family of firearms designed and manufactured by SIG Sauer, produced in both selective fire and semi-automatic only models, and features a short-stroke gas piston system, which is inherited from the earlier SIG MPX submachine gun. The MCX is available in rifle, carbine, short-barreled rifle, and pistol configurations (the latter configuration generally conforming to the definition of a compact carbine but for taking a pistol brace rather than a buttstock). [5]
The MCX was further developed into the SIG MCX Spear, which was adopted in its .277 Fury chambering as the XM7 by the U.S. Army in 2022.
The SIG MCX was first introduced at SHOT Show 2015. The rifle was originally designed by SIG USA, the subsidiary of SIG Sauer based in New Hampshire. [1] In 2016, SIG recalled some of the rifles that had the first-generation bolt carrier group. [6] It has been used by various SWAT teams and militaries, including the Ukrainian Armed Forces during the Russian Invasion of Ukraine. A SIG MCX was used in the 2016 Orlando nightclub shooting, which at the time was the deadliest mass shooting in U.S. history, now second to the 2017 Las Vegas shooting. [7]
The SIG MCX series features a short-stroke gas piston [ citation needed ] system to reduce recoil and improve the reliability of the weapon; this was based on the design of the earlier SIG MPX. [8] 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 mm STANAG magazines for 5.56×45mm NATO and .300 AAC Blackout, and specially designed STANAG-compatible magazines for 7.62×39mm. [8] [9] The MCX is designed to deliver optimal performance with .300 AAC Blackout and an optional suppressor. [10]
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. [11] [12] It features hardened steel wear points. [8] [11]
First generation MCX variants have a forend made of aluminum with a KeyMod system to add accessories while second generation MCX variants have an M-LOK handguard. Controls are mostly ambidextrous including the charging handle but not the bolt release. Sig produces four stock configurations are available for the MCX carbine. [8] [12] The overall layout of the two rifles is similar. [13] SIG designed the upper receiver to be compatible with standard AR-15 and M16 lower receivers [8] [11] with the help of an adapter. [14]
An integrally suppressed upper receiver group based on the MCX was selected by USSOCOM for the SURG (Suppressed Upper Receiver Group) contract in July 2018. These suppressed uppers would be paired with existing M4A1 lowers in SOCOM inventory. [15] [16]
The SIG MCX is available with a safe/semi-automatic trigger group for the U.S. civilian market, or safe/semi-automatic/fully automatic trigger group for the military and law enforcement agencies. [8]
SIG Sauer offers the rifle in semi-automatic only in three different configurations for the civilian market:
The SIG MCX VIRTUS is the second generation of the SIG MCX series and was introduced in 2017.
The SIG MCX RATTLER is a short-barreled rifle variant chambered in .300 AAC Blackout and 5.56. It is intended to serve as a personal defense weapon, featuring a 140 mm (5.5 in) barrel, and comes with a Picatinny rail tail interface for attaching either a compact buttstock or a folding PCB (pistol contour brace). [25] In February 2018, USSOCOM ordered upper receiver group conversion kits for the MCX Rattler in .300BLK for evaluation. [26] The MCX Rattler was later selected as the winner of SOCOM's Commercial Personal Defense Weapon (CPDW) contract in May 2022 and suppressed MCX Rattlers will be ordered in 5.56 and .300BLK. [27]
The SIG MCX-SPEAR LT is the third generation of the SIG MCX, introduced in 2022. Intended to serve as a carbine, it features 11.5-inch (290 mm) or 16-inch (410 mm) barrel and a Picatinny rail tail interface for attaching either a buttstock or a pistol brace. It is available in 5.56 mm NATO, .300 Blackout and 7.62x39mm. [28] [29]
The SIG MCX SPEAR was developed as Sig Sauer's submission for the United States Army Next Generation Squad Weapon (NGSW) program and is chambered in 6.8×51mm SIG Fury cartridge. [30] [31] [32] [33] Sig Sauer was chosen as the winner on 19 April 2022, formerly designated as the XM5 then was later changed to the XM7 in U.S. military service. [34]
The M4 carbine is a 5.56×45mm NATO, gas-operated, magazine-fed carbine developed in the United States during the 1980s. It is a shortened version of the M16A2 assault rifle.
Several sister companies that design and manufacture firearms use the brand name SIG Sauer. The original company, Schweizerische Waggonfabrik (SWF), later Schweizerische Industrie-Gesellschaft (SIG), went through several selloffs, leaving the SIG Sauer brand spread over several companies. The original SIG is now known as SIG Combibloc Group and no longer has any firearms business.
The FNSCAR is a family of gas-operated short-stroke gas piston automatic rifles developed by Belgian manufacturer FN Herstal (FN) in 2004. It is constructed with modularity for the United States Special Operations Command (SOCOM) to satisfy the requirements of the SCAR competition. This family of rifles consists of two main types. The SCAR-L, for "light", is chambered in 5.56×45mm NATO and the SCAR-H, for "heavy", is chambered in 7.62×51mm NATO. Both types are available in Close Quarters Combat (CQC), Standard (STD), and Long Barrel (LB) variants.
The 6.8mm Remington Special Purpose Cartridge is a rimless bottlenecked intermediate rifle cartridge that was developed by Remington Arms in collaboration with members of the U.S. Army Marksmanship Unit and United States Special Operations Command to possibly replace the 5.56 NATO cartridge in short barreled rifles (SBR) and carbines. Based on the .30 Remington cartridge, it is midway between the 5.56×45mm NATO and 7.62×51mm NATO in bore diameter. It uses the same diameter bullet as the .270 Winchester hunting cartridge.
The .300 Whisper (7.82x34mm) is a CIP standard cartridge in the Whisper family, a group of cartridges developed in the early 1990s by J.D. Jones of SSK Industries. It was developed as a multi-purpose cartridge, capable of utilizing relatively lightweight bullets at supersonic velocities as well as heavier bullets at subsonic velocities.
The SG 550 is an assault rifle manufactured by SIG Sauer AG in Switzerland. "SG" is an abbreviation for Sturmgewehr. The rifle is based on the earlier 5.56×45mm NATO SIG SG 540.

The .300 AAC Blackout uses standard 5.56mm NATO magazines and components with the exception of the barrel.
The CZ 805 BREN is a gas-operated modular assault rifle designed and manufactured by Česká zbrojovka Uherský Brod. The modular design enables users to change the calibre of the weapon to 5.56×45mm NATO or 7.62×39mm intermediate cartridges by quick change of barrel with gas tubes, breech block, magazine bay and magazine.
