VKTR VK-1 5.56 NATO 13.7in Short-Stroke Piston AR

Description

Overview

The VK-1 employs a patented low-profile piston system engineered for efficient gas management and consistent cycling across a range of ammunition. Its cup-and-spigot design improves the gas seal while a staged gas-bleed system helps the rifle run reliably both suppressed and unsuppressed. The reimagined VK-1 short-stroke piston includes a fully supported one-piece operating rod and a removable gas block that matches the footprint and weight of a standard direct-impingement AR-15 while offering the benefits of a piston-driven system.
