The VK-1 is a compact piston-driven rifle built around VKTR’s low-profile short-stroke piston system. The design features optimized gas port sizing, a cup-and-spigot piston assembly, and a staged gas bleed system to maintain consistent operation with a variety of factory ammunition, both suppressed and unsuppressed. The short-stroke piston uses a fully-supported one-piece op rod and a removable gas block sized to match a standard DI AR-15 footprint and weight. This configuration ships with Magpul Gen3 PMAGs, a rifle lock, and a hard case.
