The Primary Weapons Systems Mk111 Mod 2-M is a short-barrel rifle (SBR) engineered for shooters who need a compact, serious platform without compromise. Chambered in 223 Wylde, this SBR combines PWS's reputation for precision manufacturing with the practical benefits of an 11.85-inch barrel—giving you the velocity and ballistics you need for hunting, home defense, or tactical applications in a form factor that's genuinely maneuverable in tight spaces or from a vehicle. If you've been running an AR pistol and want the ergonomics, controls, and accuracy of a registered short-barrel rifle, the Mk111 Mod 2-M delivers.
223 Wylde chambering is the sweet spot for modern rifle shooters: it handles both standard 5.56 NATO loads and specialized .223 Remington ammunition, so you're not locked into one ammo type. That flexibility matters when sourcing rounds gets tight. The 11.85-inch barrel strikes a practical balance—short enough to move through doorways and truck cabs, long enough to generate reliable velocity from your chosen ammunition. This is a rifle built by PWS, a shop known for attention to detail and real-world testing, not a budget compromise.
If you're in a jurisdiction where SBRs are legal and registered (and you've got your tax stamp in order), the Mk111 Mod 2-M gives you a compact platform that doesn't sacrifice accuracy or control. It's the kind of gun you build when the space you're defending or hunting is tight, but your standards for reliability and performance are not.
