Rugged OP007 Suppressor Piston 9/16×24 Copper

The Rugged Suppressors OP007 piston is an accessory piston designed for suppressed piston-driven systems and listed to fit the Obsidian 45. It uses a non-slotted design to produce a full-circumference gas seal, which the manufacturer describes as reducing gas blowback at the shooter control interface. The piston is available with a copper finish and a 9/16×24 thread pattern for compatible hosts.

On fixed-barrel platforms such as carbines or subguns, the manufacturer notes the spring must be replaced with a fixed barrel spacer when using a piston. The OP007 is presented as a direct-fit suppressor piston accessory intended for users who prioritize reduced backflow and consistent gas sealing in piston-equipped builds.
