The Rugged Obsidian Piston in 1/2×36 (Rugged part no. OP006) is the part that attaches a Rugged Obsidian suppressor to a handgun barrel with that thread. Rugged builds its pistons without slots so they form a full circumference gas seal, and says that drastically lowers gas blowback for a more enjoyable shooting experience. The piston is machined from 17-4 stainless steel and heat treated, so it is made to last. Pistons are interchangeable between the Obsidian9 and Obsidian45, which makes this one a practical spare for either suppressor. This listing is the 1/2×36 version, so confirm your barrel thread before you order.

Key Specifications

• The thread pitch is 1/2×36, which has to match the barrel the piston goes on.
• The design is non-slotted, giving a full circumference gas seal that lowers blowback.
• The material is 17-4 stainless steel, heat treated so the piston holds up to repeated use.
• Handgun setups generally pair the piston with a booster system, the usual way to run an Obsidian on a pistol.
• On a fixed barrel carbine or subgun the spring is replaced with a Fixed Barrel Spacer when a piston is fitted.
