The Primary Weapon Systems MK118 Mod 1-M is a complete upper receiver assembly chambered in 6mm ARC, featuring an 18-inch barrel with a long-stroke (LS) piston-driven operating system and threaded muzzle. Built on PWS's proven Mod 1-M platform, this upper offers enhanced reliability and reduced fouling compared to direct-impingement designs. Compatible with standard AR-15 lower receivers, it is well-suited for precision rifle applications requiring the flat-shooting performance of 6mm ARC.
