Piston driven ARs are favorites among many shooters due to the advantages that they offer over direct impingement systems, but one problem with piston guns is the added weight that comes with a piston system. To try to solve that issue, the engineers at VKTR Industries created a the VK-1 piston system which offers all the piston benefits but with the same footprint and weight of a standard direct impingement system. The VK1PW rifle utilizes this system, with optimum gas port sizing, an improved gas seal, and a staged gas bleed system that reduces the operating rod’s inertia.

The VK-1 is a lightweight, low profile, feature-rich, piston driven AR-15 for the discerning shooter, features patented state of the art internal components, offering shooters a flatter, cleaner, more consistent shooting experience than traditional DI or legacy piston driven AR’s… in the lowest profile footprint on the market.
