Piston 13.5M x 1LH

This versatile suppressor piston assembly represents advanced modular suppressor technology designed for maximum flexibility across multiple host platforms. Constructed from premium 17-4 stainless steel and precision heat treated for exceptional durability, the piston integrates the Nielsen device mechanism that enables reliable semi-automatic cycling while housing the female threads for secure muzzle attachment. The .578"x28 threading accommodates a wide range of compatible host weapons. The interchangeable piston design allows shooters to quickly adapt this suppressor family—including OMEGA K Series, OSPREY, OCTANE, and HYBRID 46 models—for different calibers and firearm types. This multi-caliber capability means a single suppressor platform can function across various subcaliber applications, eliminating the need for multiple dedicated units. The modular approach delivers significant versatility and value for shooters seeking efficient, flexible sound mitigation solutions across their firearm collection.
