Rugged Piston Obsidian 1/2x28

Rugged Obsidian PistonsThe Rugged Obsidian Pistons feature a non-slotted design that creates a full circumference gas seal, drastically reducing blowback for a smoother shooting experience. Machined from heat-treated 17-4 stainless steel, these pistons are built for long-lasting durability.Designed for use with Rugged Obsidian 9 or 45 suppressors on handguns, the pistons are available in multiple thread pitches, making it easy to swap pistons and run a single suppressor across different handguns.When used on fixed-barrel platforms like carbines or subguns, the factory spring must be replaced with a Fixed Barrel Spacer for proper function.
