Among the myriad introductions at SHOT Show 2019 was a straight-wall rifle cartridge dubbed 350 Legend. The leading company behind the charge is Winchester, but it wasn’t until a day later that CMMG Inc., announced not only a rifle, but a series of direct-impingement semi-automatics compatible for use with this newly designed cartridge. At the top tier of the series, the Resolute 300 MK4 boasts forged aluminum receivers featuring Cerakote finishes and components AR builders know the company for. To learn more, watch our NRA Gun of the Week video hosted by American Rifleman’s Kelly Young.
