New for 2024, Sig Sauer has unveiled the all-new MCX-R Regulator, a semiautomatic rifle offered in three models, including two chambered in 5.56 NATO and one in 7.62x39mm.
All three models feature proprietary SIG 2-Stage match triggers, an aluminum frame with Gen II NiR FDE Ceraokote finish, and a cold hammer-forged carbon steel barrel with an FNC finish. The semi-auto rifles offer a fully ambidextrous 30-degree safety paddle, bolt catch/release, charging handle, and magazine release.
In addition, the MCX-R Regulator was designed to accept Magpul 500/590/590A1-style stocks, and it features an integrated ARCA rail, while the lower receiver is compatible with all MCX upper receivers.
