Our piston stands apart from the rest thanks to its innovative non-slotted design which creates a complete gas seal, greatly reducing gas blowback and enhancing your shooting experience. Made from tough 17-4 stainless steel and subjected to rigorous heat treatment, this piston is built to last. While pistons are commonly used with booster systems in handguns, they can also be applied to fixed barrel platforms such as carbines or sub guns, with the spring being replaced by a fixed barrel Spacer.
