Product Description The Rugged Suppressors Piston (1/2x28) is engineered to improve suppressed pistol performance by minimizing gas blowback. Its non-slotted design creates a full-circumference gas seal for a more comfortable shooting experience. Machined from durable 17-4 stainless steel and heat treated for long-term wear resistance, this piston is built for hard use. When installing a piston on a fixed-barrel platform such as a carbine or subgun, the spring must be replaced with a fixed barrel spacer.
