Rugged Suppressor OP004 Piston M13.5x1 LH Copper 17-4 Stainless Steel

The Rugged Suppressor OP004 Piston is a precision-machined accessory for the Rugged Obsidian suppressor system, designed to mount the can on a host barrel threaded in M13.5x1 LH.

Unlike traditional slotted piston designs, the OP004 uses a non-slotted configuration that creates a full-circumference gas seal. This dramatically reduces gas blowback into the shooter's face for a much more pleasant shooting experience, and makes the OP004 an ideal choice on fixed-barrel platforms such as carbines or subguns.

The piston is machined from heat-treated 17-4 stainless steel for lasting service under repeated fire, and finished in a striking copper tone. Its left-hand thread pattern delivers a tight, repeatable lock-up with the host barrel.
