VKTR VK-1 5.56 NATO 13.7in HUXWRX Piston AR

About this product

The VKTR VK-1 is an AR-style rifle that uses a patented low-profile short-stroke piston system for consistent cycling with a variety of factory ammunition. Its staged gas bleed system and advanced piston assembly are designed to maintain reliable operation both suppressed and unsuppressed. The VK-1 short-stroke piston design 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 delivering the benefits of a piston-driven system.
