*M16x1 LH Piston is NOT compatible with Kriss Vector Firearm Hosts
Our piston uses a non-slotted design creating a full circumference gas seal. This drastically lowers gas blowback for a more enjoyable shooting experience. Machined from 17-4 Stainless Steel and heat treated this piston is built to last.
Pistons are generally used with a booster system on handguns. 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.
