Product Description The Rugged Suppressors OP005 suppressor piston features a non-slotted design that creates a full-circumference gas seal to drastically reduce gas blowback for a more enjoyable shooting experience. Machined from heat-treated 17-4 stainless steel with a copper finish, this piston is built for long-lasting durability. 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.
