The SIG MCX has been a giant success for SIG Sauer. It’s their premier rifle and serves the civilian, army, and police markets. What I really like about SIG Sauer is that they’re virtually at all times prepared and capable of produce the identical variants they produce for army forces, sans choose hearth, for the common Joe. It’s a giant promoting level. With that in thoughts, how usually is the army utilizing the SIG MCX?
You’d be shocked. The MCX has seen a good bit of success within the army, with 5 fashions being adopted by varied forces. Properly, five-ish fashions, however we’ll get into it. First, what precisely is the MCX? Let’s preserve it a one-paragraph clarification.
The MCX is a modular rifle system designed to be simply transformed to numerous calibers in a mess of sizes. The weapon operates off a short-stroke fuel piston design and makes use of an higher and decrease receiver group. It negates the necessity for a receiver extension and permits for folding shares. Moreover, SIG correctly tailored quite a few AR influences relating to the gun’s ergonomics, format, and journal.

M7 – Huge Military
Clearly, the massive topic of the present army small arms dialogue is the M7, a.ok.a. the XM5, a.ok.a. the SIG SPEAR in 6.8x51mm. The M7’s purpose is to mix a rifle with a hearth management unit that may prolong a person’s efficient vary and enhance an infantryman’s lethality. Armor-piercing operate is desired, and this new, tremendous high-velocity, high-pressure spherical is fascinating.
The SIG SPEAR is the AR-10 of the SIG MCX collection. It’s designed for full-powered calibers, just like the 6.8x51mm, but in addition 7.62x51mm and 6.5 Creedmoor. To make use of the frequent parlance, it’s a battle rifle that maintains the short-stroke fuel piston design and modularity of the SIG MCX collection, simply greater and extra highly effective.

The M7 rifle is aiming to determine an overmatch functionality towards different army forces. The power to hit them earlier than they hit you is at all times a legitimate tactic. Whereas the M7 hasn’t been fielded extensively simply but, time will inform if the idea performs out. I believe the Military’s expectations are a bit a lot for an infantry rifle, however what do I do know?
LVAW – JSOC
From what I can inform, the LVAW was the primary adoption of the SIG MCX collection by a army pressure. LVAW stands for Low-Visibility Assault Weapon, and it’s primarily a rifle-powered submachine gun alternative. Because the title implies, it’s designed to be low-vis, and that necessitates each a brief and compact platform and a quiet one.

The LVAW is designed to be run suppressed, a lot in order that the barrel ends earlier than the rail, and the rail encompasses a portion of the suppressor. The rifle fires the .300 Blackout cartridge, which makes it simple to suppress with subsonic masses, however permits for a simple swap to supersonic for extended-range engagements.
The LVAW has been seen in use by elite forces and was a JSOC program. This implies DEVGRU (a.ok.a. SEAL Crew 6) and CAG (a.ok.a. Delta) are fielding the platform for specialised mission roles. Notably, it’s been seen as a part of personnel safety particulars.
CSAW – JSOC
One other JSOC MCX is the CSAW variant. Whereas the LVAW is the ultra-small platform, the CSAW, or Shut Assist Assault Weapon, is a extra conventional assault rifle. It does sport a ten.5- or 14.5-inch barrel, so it’s within the Mk18/M4 dimension profile.

It’s a 5.56 rifle that can be utilized the identical method because the HK 416D, the Mk18, and comparable platforms. It’s an all-around city fight platform. It bears mentioning that the CSAW title has additionally been used with rifles just like the HK 416.
The CSAW is predicated on the SIG MCX SPEAR-LT, to not be confused with the heavy-duty SPEAR. SIG will get somewhat nutty with their naming conventions; the LT means Mild, which implies 5.56 or different intermediate cartridges. The CSAW variant is issued with the SIG SLX556C-QD suppressor.

This variant additionally reportedly options strategic use of titanium to lighten weight with out decreasing power. It’s unclear how far and large the MCX CSAW has been issued, however Delta operators securing a Presidential occasion in Tel Aviv had been seen wielding this new variation of the SIG MCX.
RSAR – SOCOM
SOCOM bought the SIG Rattler, a PDW-sized platform of the MCX, and designated it the RSAR. RSAR stands for Diminished Signature Assault Rifle, and SOCOM bought each .300 Blackout and 5.56 variants of this super-short rifle. The barrel size of the RSAR is 7.75 inches.
Commercial — Proceed Studying Beneath
It’s been theorized that the 5.56 variants had been bought for coaching functions and the .300 Blackout was for operational use. The .300 Blackout performs a lot better from brief barrels than 5.56. Very like the LVAW, the RSAR can be fielded with a suppressor to cut back the rifle’s signature. One fascinating a part of the contract talked about a 7.62x39mm model as effectively.
This uber-small weapon will serve with private safety particulars and for low-visibility operations. It’s extremely small and light-weight. SIG made a model of the RSAR out there for the industrial market because the RSAR999.
SURG – SOCOM
Keep in mind after I stated five-ish? Properly, the five-ish comes all the way down to the SURG. SURG stands for Suppressed Higher Receiver Group. It’s not a whole weapon; it’s a suppressed higher receiver designed to outfit M4A1 decrease receivers. The SURG can also be out there on the civilian market however requires a tax stamp.
The SURG collection incorporates a direct-thread Inconel suppressor that’s surrounded by a titanium warmth defend. It resembles a cage. That is to forestall operator burns when utilized in shut quarters and helps cut back suppressor mirage when used extensively.
The short-stroke fuel piston system prevents fuel blowback to the operator’s face and permits for wonderful and cozy suppression. Of all of the weapons on this checklist, that is the one one I’ve personally fired, and I completely adored it.
The MCX In Army Service
The MCX collection helped jump-start fashionable short-stroke piston designs. It’s remained a very talked-about choice for particular operations use, and with the M7, it’s changing into the primary firearm of the USA Military. The long run is vivid for the MCX.
