Sig Sauer MCX-R Regulator 5.56 NATO/223 Rem 16" Barrel 10+1 with Romeo 2 Red Dot

The MCX‑R Regulator channels the rugged reliability of SIG’s renowned MCX platform into a precision-ready, ranch-style rifle. Built with a cold hammer-forged 16-inch carbon steel barrel featuring a 1:7 twist rate and topped with SIG’s two-port compensator, it delivers tight accuracy paired with reduced recoil and muzzle rise. The alloy receiver is finished in Gen II NiR FDE Cerakote for enhanced durability and heat resistance, while the Magpul SGA stock—borrowed from the Mossberg 500/590 family—allows shooters to swap or customize the stock to their preference.

This ambidextrous, semi-auto rifle is equipped with a two-stage match-grade trigger and fully ambidextrous controls, including the mag release, safety selector, and bolt catch. It comes optics-ready and includes SIG’s ROMEO2 red dot sight with a 3 MOA dot for fast and precise target acquisition. Additional features include a receiver-integrated ARCA rail for tripod stability and compatibility with any MCX upper assembly, offering a modular platform for caliber or barrel-length changes. The MCX‑R Regulator blends tactical versatility with refined performance for shooters who want more out of their modern rifle.
