The VKTR VK-1 Complete Upper packages a short, hard-hitting 5.56 upper receiver into a mission-ready assembly built for compact rifles and pistol builds. At 11.5" with a heavy-profile, nitride-finished barrel and 1/2×28 threading, this upper is optimized for suppressed or compensator-equipped hosts while preserving balance and durability. The thermal-fit forged upper, continuous 12 o’clock Picatinny, and low-profile M-LOK handguard give you a solid mounting platform for optics and mission accessories.
