Rugged Suppressors Obsidian Piston — 17-4 Stainless

The Rugged Suppressors Obsidian piston is a replacement piston designed for use with the Obsidian series. It uses a non-slotted design to create a full-circumference gas seal, which helps reduce gas blowback and improve the shooter experience. The piston is machined from 17-4 stainless steel and is heat treated for durability, and it is finished in copper.

When installed on fixed-barrel platforms such as carbines or subguns, the spring must be replaced with a fixed-barrel spacer to ensure proper function. This piston is offered for users who need a durable, serviceable component to match the Obsidian suppressor family.
