Engineered for duty-rated, hard-use 5.56 suppression in short-length configurations. Designed for rapid deployment and sustained strings of fire while minimizing signature and back pressure relative to longer systems. The K configuration prioritizes compactness and manageability for operators who require a short, rugged suppressor that cools quickly under repeat use.

Built for durability and modular mounting, the Polonium K combines a tubeless, welded CNC design with H900 heat-treated 17-4 stainless steel construction. The unit includes a 1/2×28 direct-thread adapter and a tube clamp for changing mounts, and it accepts common mounting systems via an industry-standard rear thread housing.

Key Specifications

• Caliber: 5.56 — duty-rated suppression for 5.56 NATO platforms.
• Bore compatibility: 6mm — compatible with 6mm/.243 cartridges as specified by manufacturer.
• Material: H900 heat-treated 17-4 stainless steel — welded, tubeless CNC construction for strength under repeated use.
• Length (Polonium-K): 4.80 in — compact K-length profile for short-barrel and lightweight builds.
• Outer diameter: 1.625 in — reduced profile for improved ergonomics and handling.
• Rear thread housing: 1.375×24 — industry-standard rear threads for modular mount selection.
• Included adapter: 1/2×28 direct-thread — supplied for direct-thread mounting on 5.56 barrels.
• Integrated flash reduction — internal and external flash-hiding geometry intended to lower visual signature with NV use.
• Construction: welded tubeless design — sheds heat efficiently and reduces internal failure points.
• Full-auto rated — rated for full-auto operation per manufacturer specification.

Mission Brief: The Polonium K fills the short-length suppression role for operators who need a compact, duty-rated suppressor that integrates with common mounting systems and prioritizes heat-shedding and low-profile ergonomics. Use it to reduce muzzle signature and back pressure on short-barrel 5.56 platforms while maintaining a robust, serviceable construction.
