CALIFORNIA LEGAL #MCX - Regulator
The Sig Sauer MCX Regulator offers a California-legal configuration by integrating MCX uppers with Mossberg 500 stocks. It features modularity for caliber swaps (5.56, 7.62x39, 300 Blackout), fully ambidextrous controls, a two-stage match trigger, and a cold hammer-forged barrel. A notable feature is the integrated Arca rail for tripod mounting, finished with infrared-resistant Cerakote.
