Design and modular compatibility

The two-piece receiver design and proprietary ranch rifle lower make the SIG SAUER MCX-REGULATOR immediately familiar to MCX users while offering distinct field advantages. The lower is compatible with all MCX upper receivers, enabling quick caliber or barrel changes for mission-specific setups. It also accepts many aftermarket 500/590 stocks and ships with a Magpul SGA 500/590 stock for instant ergonomics tailored to shoulder carry and quick target acquisition.

Controls and finish

Fully ambidextrous controls and a two-stage match trigger ensure reliable manipulation and a crisp pull for precision shots. The Gen II NiR Cerakote finish in Coyote Brown protects the receiver from the elements while providing a low-glare, tactical appearance. An integrated receiver ARCA rail adds mounting flexibility for bipods and field accessories.

Caliber choice and field performance

Chambered in 7.62x39mm, the MCX-REGULATOR leverages a cartridge known for good terminal performance on medium pests at practical ranges, with readily available ammunition and favorable recoil for quick follow-up shots. The semi-auto platform combined with the two-stage trigger helps deliver accurate, controlled fire when seconds count.

Price is set at $2999.99, and the package includes one 10-round magazine—an option-minded balance for states with magazine capacity limits while still offering practical field utility. View product details and pricing
