The Rugged Suppressors Obsidian piston is designed for compatible suppressor applications using a 1/2×28 thread pattern. Its non-slotted design creates a full-circumference gas seal, while heat-treated 17-4 stainless steel provides durable construction.

The piston measures 1.55 x 1.40 x 2.50 inches and features a copper finish. When used on a fixed-barrel platform such as a carbine or subgun, the manufacturer specifies replacing the spring with a Fixed Barrel Spacer.
