The SIG Sauer System with John Hollister
John Hollister, SIG Sauer's Product Manager for Silencers, details the SIG Sauer system's modularity and complete provider approach. The SIG MCX rifle is highlighted for its quick caliber conversion between 5.56 NATO and 300 Blackout by simply swapping the barrel. The system also emphasizes integrated optics like the Bravo 4, silencers such as the SRD 556 QD, and proprietary features like a steel cam path and charging handle pins for enhanced durability.
