Primary Weapons Systems MK1 Compound SBR .223 Wylde 11.85" Barrel
Kodiak / FDE Anodized Finish

The PWS MK111 Compound SBR is built for shooters who refuse to compromise—combining the rugged Mod 1 upper with the refined, fully ambidextrous Mod 2 lower to create a rifle that excels in precision, reliability, and adaptability. This hybrid design captures everything enthusiasts love about PWS: long‑stroke piston reliability, exceptional ergonomics, and a shooting experience engineered to run clean and smooth in both suppressed and unsuppressed configurations.

At its core is an 11.85" .223 Wylde precision barrel, delivering sub‑MOA accuracy with premium ammunition and offering the flexibility to run both .223 Remington and 5.56 NATO. The PWS long‑stroke piston system minimizes fouling and reduces gas blowback, while the adjustable gas block ensures optimal performance with or without a suppressor. The rifle’s sleek full‑length M‑LOK™ handguard, Radian Raptor charging handle, and ambidextrous Mod 2 lower elevate handling and control to a new level.

Finished in a collectible Kodiak Brown / FDE anodized finish*, the MK111 Compound SBR blends modern engineering with a distinctive aesthetic that pairs beautifully with FDE accessories. Lightweight, balanced, and built with premium components throughout, this rifle is designed for shooters who demand performance, modularity, and a truly elevated shooting experience.
