Description
Rugged Obsidian Piston
The Rugged Obsidian 45 Piston with .578×28 thread pattern; 17-4 stainless steel construction; and copper finish.
Featuring a non-slotted design, this piston from Rugged Suppressors creates a full circumference gas seal which drastically reduces gas blowback, resulting to a more enjoyable shooting experience.
The Obsidian 45 Piston is machined from 17-4 stainless steel and heat treated, and so is set for a long service life.
*When using a piston on a fixed barrel platform such as a carbine or subgun the spring must be replaced with a fixed barrel spacer.
