Rugged Suppressors Obsidian Piston M13.5x1 LH Copper

The Rugged Suppressors Obsidian Piston is a replacement piston for Rugged Obsidian suppressors. It uses a non-slotted design that creates a full circumference gas seal, which the manufacturer states helps lower gas blowback. The piston is machined from 17-4 stainless steel and heat treated for durability, and it is finished in copper.

The piston is listed with M13.5x1 LH threads and a left-hand orientation. It is intended for Obsidian suppressors using that thread pitch. When used on a fixed barrel platform such as a carbine or subgun, the spring must be replaced with a fixed barrel spacer to keep the system properly configured for the host.
