Rugged Obsidian .578x28 Suppressor Piston

Rugged Obsidian Suppressor Piston

The Rugged Obsidian piston represents a thoughtful approach to suppressor design. Built around a non-slotted design philosophy, this piston creates a complete circumference gas seal that significantly reduces gas blowback—a consideration that matters whether you're shooting suppressed rifles or pistols.

Construction and Durability

Material: 17-4 Stainless Steel, heat treated for maximum durability

Thread Pattern: .578x28

The machining and heat treatment process ensures this piston will withstand repeated use and cleaning cycles without degradation.

Performance Benefits

• Reduced Blowback: The full circumference gas seal minimizes gas escaping rearward, creating a more pleasant shooting experience
• Reliable Sealing: Non-slotted design maintains consistent performance across various ammunition types
• Built to Last: Heat-treated stainless steel construction handles the demands of regular use

Important Compatibility Note

When installing this piston on fixed barrel platforms—such as carbines or submachine guns—you must replace the spring with a fixed barrel spacer. This modification ensures proper function and safety on non-reciprocating systems.

The Rugged Obsidian piston is an excellent choice for shooters seeking to reduce felt recoil and muzzle blast while maintaining reliable suppressor performance.
