The Primary Weapons Systems MK111 Mod 2-M Pistol 338 ARC 11.85 SBA5 FRC brings PWS’s proven long-stroke piston system to a compact, hard-hitting AR-style pistol. Chambered in .338 ARC and built around an 11.85" barrel, this platform is tuned for efficient energy delivery and reliable performance, especially when run suppressed. Its lightweight construction and free-float M-LOK rail keep the front end agile while the included compensator helps manage recoil and muzzle movement.
This MK111 Mod 2-M configuration is purpose-built for hunters and shooters who want maximum performance from a short, maneuverable package. The SBA3 adjustable brace supports stable shooting from a variety of positions, making it well suited for field carry, range work, and varmint or predator applications where quick handling matters. Combining modern ergonomics with PWS’s refined piston engineering, it reflects the manufacturer’s focus on innovation, durability, and practical accuracy.
