Meet the SIG MCX Regulator: the new kid on the block from SIG SAUER that’s stirring the pot and making waves. It’s built on the tried-and-true MCX platform but brings its own flavor to the table, aiming to shake up what we think of when we hear “ranch rifle.” But don’t get it twisted; while it’s pitched as the next big thing for ranchers, farmers, and cowboys, there’s more to this story.

The Specs to Know:

  • Caliber Options: 5.56 NATO and 7.62x39mm
  • Overall Length: 38.9 inches
  • Barrel Length: 16 inches
  • Weight (with magazine): 7.9 lbs
  • Barrel Twist: 1:7 (5.56) and 1:9.5 (7.62×39)
  • Frame: Aluminum with Gen II NiR FDE Cerakote™ for that stealthy vibe
  • Stock: Magpul™ SGA Mossberg 500/590 style (yeah, the traditional kind)
  • Features: Fully ambidextrous controls, two-stage match trigger, SIG designed muzzle brake, built-in Arca Rail for easy tripod mounting, and ships with a 10-round magazine.

The SIG MCX Regulator has fully ambi controls. Some of them are a little hard to reach with your firing hand.

Now, onto the juice. Some folks on Instagram and YouTube weren’t feeling it, calling SIG out of touch. But here’s the deal: the Regulator might not be for everyone, and that’s okay. It’s like SIG took the MCX, jazzed it up with some legal loophole magic, and made it so folks in states with tight gun laws can actually enjoy some high-quality SIG action. If your state doesn’t allow threaded barrels, simply pin and weld the muzzle brake. If your state doesn’t allow muzzle attachments, pin weld a thread protector.

The safety reminds me of 1911…down for off, up for on.

Despite the ranch rifle tag, the Regulator is playing a different game. It’s loaded with features like IR signature reduction paint and a gas-piston system that’s more about keeping things low-key and compliant than herding cattle or taking down hogs. Let’s be real, no rancher is obsessing over IR signatures.

But here’s where it shines: for those stuck in states where the AR-15 is a no-go, this rifle is a game-changer. It’s got the guts of an MCX with a few tweaks to keep it on the right side of the law. So, if you’re looking to exercise your 2nd Amendment rights without moving states, the MCX Regulator might just be your ticket.

Right side of SIG MCX Regulator
The upper is a SIG MCX upper and will fit onto an MCX lower or an AR15 with the adapter that SIG sells. So should your state or the Supreme Court change the laws you’re future-proofed.

What’s Cool and What’s Not:

  • Cool: It’s SIG quality through and through, with adaptability for different legal landscapes. The upper is an MCX upper just like what Tier One guys are running.
  • Not So Cool: The controls might feel a bit out of reach for some, especially if you’re used to the ergonomics of a traditional AR. You can’t reach the mag release, or bolt hold open/release with your firing hand. It’s just too far away.

The trigger magic inside the Regulator.

The MCX Regulator is a sign of the times, offering a solid option for those in restrictive states. It’s a bit of a niche player but in a league of its own for the right crowd. And at around $2,699, it’s priced in line with what you’d expect for a high-quality piece of SIG craftsmanship.

Spacers for the MCX Regulator Stock
The stock uses any Mossberg 500/590 shotgun stock and comes with spacers for length of pull and cheekpiece height.

To wrap it up, the MCX Regulator is one interesting piece of hardware. It might not be everyone’s cup of tea, especially if you’ve got free rein over your gun choices. But for those navigating the maze of state restrictions, it’s a beacon of hope. Not just a “ranch rifle,” but a symbol of adaptability and SIG’s commitment to serving all shooters, no matter where they hang their hats.

    whats ridiculous is that remington lawsuit. how did they prove that bushmasters marketing actually caused that evil, mentally disturbed young boy to shoot his mom who left the guns out, then go shoot up sandy hook? the settlement was a similar travesty in the justice system and sets a dangerous precedent. sleeze ball trial lawyers made alot of money on that one. the connecticut supreme court is a joke.

    $2700 LOL…. I think I’ll pass

    I used to get a monthly newsletter , but for some reason, I don’t get it anymore? Did you quit publishing it? If you still publish it will you please put me on your e-mailing list please add me. [email protected]
    Thank you

    264 bucks for a CVlife? The famous Amazon disposable optic company? That’s really funny.

  • Matthew A. Carpenter March 13, 2024, 6:19 am

    And for half the cost you can buy a Fight Lite SCR rifle lower (Which you can but any AR-15 upper on) and an Adams Arms piston upper that will be totally bombproof and be compatible most commonly available AR-15 components.
    Or you could buy a Kel-Tec SU-16 which will likely be one third the price of the sig and still have a rifle that is basically bombproof.

  • Mark N. March 12, 2024, 11:29 pm

    Definitely a California compliant rifle (as is the Ruger Mini), and the weight is good, but that price point is more than I care to bite off.

  • Buckshott00 March 11, 2024, 7:48 pm

    So they copied the Kel-tec SU-16 but made it into something for production…
    If you’re going to go this far, why not put the Spear’s guts into it? Or FFS offer the 6.8SPC since it should have the same barrel dimension as your .277Fury
    Not to mention the probably aren’t planning to sell too many of these if their whole pitch is “it’s 49 state friendly (minus IL), like the Mini, but 3X the price!” cause ranchers and normal folk have $1k lying around for a rifle let alone $3k

    The price on this is pretty close to enough to buy/build 3 AR style rifles plus only one barrel length available? Not a chance of a snowball in Hell.

  • James Policke March 11, 2024, 1:01 pm

    Dumbest product planning I’ve ever seen. So you make a rifle that’s all about compliance in ban states and stick a threaded barrel on it? Because “all I have to do is get it pinned and welded”? Because you can find a place to do that anywhere and have it done for pennies, right?
    FAIL.

    No, just no

  • Tenbones March 11, 2024, 8:51 am

    Way too expensive by at least half….makes like or don’t like comments irrelevant.

  • Glen Williams March 11, 2024, 8:23 am

    Sig has not had 1, and I mean 1 original idea at all. The MCX is an overpriced ripoff. Fightlite and Foxtrot Mike do this same ranch style rifle. And quite well I might add. Sig needs to wipe their mouth and stick to overpriced gumment contracts.

  • Kane March 10, 2024, 9:36 pm

    Watched the video and read the article and it’s still hard to believe that this SIG MCX Regulator will be in any gun stores in IL without a USSC reversal of the PICA.
