Piston 9/16 x 24

This piston assembly is engineered for the OMEGA K Series, OSPREY, OCTANE, and HYBRID 46 suppressor platforms, featuring .578"x28 muzzle threads. Constructed from 17-4 stainless steel and heat-treated for exceptional durability, the piston integrates the Nielsen device mechanism that enables semi-automatic cycling while housing the female threads for secure muzzle attachment. The design allows quick interchangeability across multiple host weapons and calibers, transforming these suppressors into true multi-caliber systems. Users can switch between different host guns or transition to subcaliber configurations without replacing the suppressor body itself. This modular approach maximizes versatility and value, enabling shooters to maintain compatibility across various platforms with a single suppressor core. Replacement pistons are essential wear items for suppressor maintenance and caliber transitions.
