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 7.62x39 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.
