The VKTR Industries VK-1 is a piston-driven 5.56 NATO rifle (brand part no. V31100916648) built around a 13.7-inch cold hammer-forged barrel that is pinned and welded with a muzzle device to a legal 16-inch overall length, keeping this configuration a standard rifle rather than an NFA-regulated short-barrel rifle. VKTR Industries engineered the VK-1 around a low-profile piston system with a cup-and-spigot gas seal for cleaner, cooler-running operation than a direct-impingement AR-15. The rifle wears a sniper gray Cerakote finish over the receiver with an ambidextrous selector switch, and it ships complete with a Magpul MOE SL stock and Magpul K2 grip. It’s built for shooters who want AR-15 ergonomics with the reduced fouling and heat of a piston-driven action.
