Rugged Suppressor OP005 Piston M16x1 RH Copper 17-4 Stainless Steel

The Rugged Suppressor OP005 is a direct-fit suppressor piston designed for use with Rugged Suppressor's Obsidian pistol-caliber silencers. Machined from heat-treated 17-4 stainless steel and finished in a distinctive copper tone, this rugged little component turns a fixed-mount Obsidian into a piston-driven setup for semi-automatic hosts cut with an M16x1 right-hand thread.

Unlike traditional slotted pistons, the OP005 uses a non-slotted design that creates a full-circumference gas seal inside the booster housing. The result is dramatically reduced gas blowback toward the shooter's face, translating into a noticeably more pleasant shooting experience every time the action cycles.

Built to last, the piston is precision-machined and heat treated for long service life under repeated high-pressure use. The copper finish gives the part a clean, professional appearance and makes it easy to differentiate thread pitches at a glance on a crowded workbench. Whether switching hosts or replacing a worn unit, the OP005 is a simple, reliable upgrade for any Rugged Obsidian system.
