SIG SAUER has expanded its popular MCX lineup to include more than a dozen variants of both the SPEAR and Rattler models. They can be had in a variety of configurations, finishes, and calibers, all equipped with standard pistol grips – until now. SIG recently announced their newest MCX model, dubbed the Regulator, which incorporates a Magpul Mossberg 500/590 style stock in place of the pistol grip we’ve come to expect. They’re marketing this variant as a ranch rifle, which is a role it could certainly fill, but arguably the greatest benefit offered by the MCX-Regulator is its potential for compatibility with ban state compliance. If your state frowns upon features such as pistol grips or threaded barrels, this rifle may be able to provide you with a legal AR alternative either straight out of the box or with a relatively simple modification like a pin-and-weld job, depending upon your particular residence. Check out the press release below for further details on this newest MCX.

SIG SAUER MCX-REGULATOR: Redefining the Ranch Rifle

NEWINGTON, N.H., (March 7, 2024) – Built on the legendary MCX platform, SIG SAUER is pleased to introduce the MCX-REGULATOR for an entirely new level of modularity.  This newest addition to the MCX family combines the upper receiver of the MCX SPEAR-LT and gas piston system used by Elite Special Forces worldwide with a newly designed lower receiver, trigger and stock, forever redefining the ranch rifle.

“The heart and soul of this rifle is one of our flagship products – the legendary MCX,” said Tom Taylor, Chief Marketing Officer and Executive Vice President, Commercial Sales, SIG SAUER, Inc.  “This is the first time the DNA of an Elite Special Forces battle platform, flawless function, and a short stroke gas piston system has been specifically designed and visioned for the working rifle.  At SIG we don’t subscribe to the premise that its acceptable to compromise for any purpose, including your working rifle, and this rifle will revolutionize a day at the ranch or however you use your REGULATOR.”

The MCX-REGULATOR is an aluminum frame rifle with a gas-piston operating system, a Magpul™ SGA Mossberg 500/590 traditional stock in a Gen II NiR FDE Cerakote™ for reduced IR Signature.  The platform features a redesigned lower receiver compatible with all MCX upper receivers, a fully ambidextrous magazine release, safety selector, and bolt catch. The MCX-REGULATOR ships with a two-stage match trigger, a cold hammer-forged carbon steel barrel, a SIG designed muzzle brake, and is available in 7.62×39 and 5.56 calibers.  The MCX-REGULATOR offers a built in Arca Rail for easy tripod mounting and ships with a 10-round magazine.

Additionally, the MCX-REGULATOR is available in with a factory installed mil-spec ROMEO2 optic. The optic features a molded glass aspheric lens with high-performance coatings for superior light transmittance and zero distortion, D.A.R.C. (Dark Adaptive Reticles and Coatings) technology to provide ideal reticle brightness and target clarity during the day or under night vision, MOTAC™ (motion-activated illumination system) automatically turns the optic off when not in use, and automatically turns it back on when it detects motion, and MAGNETAC™ (Magnetic Activation) automatically turns the optic off when holstered in a compatible holster, and on when drawn. The sight has a 7075-aluminum housing and comes with a full shroud installed to fully enclosed and seal the sight. A spring-loaded side battery tray with push-button release allows a battery change without the need to remove the optic from the firearm.

As is SIG’s custom, their official material doesn’t list pricing. However, based on knowledge about the prices of prior MCX models and a bit of quick internet sleuthing, it would be reasonable to expect MSRPs of approximately $2999.99 for the optics-ready versions and $3499.99 for a Regulator with an included ROMEO2. This would seem to position it as a sort of premium upgrade option when compared with some lower-priced competitors of a similar style, such as the Mini-14 or FightLite SCR models.

So if you have a ranch or live in California, or you live on a ranch in California, is the MCX-Regulator for you? What do you think about this newest MCX offering? Does it seem to fit a needed niche and do you think it will be good value for money in that niche? Would you prefer one of the more budget-friendly competitors mentioned above, or something else not listed? Do you have any experience with SIG’s other MCX models, and how have you liked those?
