Rugged Suppressor OP009 Internal Shoulder Piston 1/2x28 Copper

The Rugged Suppressor OP009 is an OEM Internal Shoulder Piston machined from heat-treated 17-4 Stainless Steel and finished in Copper. Built as a direct-fit replacement or spare for the Rugged Obsidian 9 and Obsidian 45 pistol suppressors, the OP009 threads onto a host pistol barrel at 1/2"-28 tpi and serves as the moving interface that the suppressor body indexes onto during the firing cycle.

The piston's non-slotted gas seal design creates a full-circumference seal against the suppressor bore, dramatically lowering gas blowback to the shooter's face compared to conventional slotted piston designs. Rugged's heat-treated 17-4 stainless steel construction gives the piston the strength and wear resistance needed to withstand repeated suppressed fire, while the Copper finish provides corrosion resistance and a distinctive factory look on the host barrel.

This Internal Shoulder configuration is specifically engineered for use with the Glock 43 and Sig P938, as well as other host pistols sharing the same barrel shoulder geometry and thread pitch. Whether you are running a dedicated suppressed pistol or want a backup piston on hand for your Rugged Obsidian setup, the OP009 delivers the same OEM quality supplied with Rugged Suppressor's factory-built accessories.
