Rugged Obsidian Piston (M13.5x1LH)

The Rugged Obsidian Piston with M13.5x1LH thread pattern; 17-4 stainless steel construction; and copper finish.

Thanks to its non-slotted design, this Rugged Suppressors piston creates a full circumference gas seal which drastically reduces gas blowback, making your shooting experience more enjoyable.

In terms of construction, the Obsidian M13.5x1LH Piston is machined from 17-4 stainless steel and heat treated, and this makes it very durable.

*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.
