VKTR V31100916620CA | 5.56 NATO | 13.7″ Barrel

The VKTR V31100916620CA is a compact AR-pattern rifle built around VKTR’s low-profile short-stroke piston system and a 13.7-inch threaded barrel. The piston design uses a cup-and-spigot seal and staged gas bleed to maintain reliable operation with a range of factory ammunition whether suppressed or unsuppressed. This California-compliant configuration includes a Gen3 Compmag, rifle lock, hard case, and a HUXWRX flash hider that is pinned and welded to meet a 16″ barrel length requirement for sale in California. A capable optic option that pairs well with this platform is the Vortex Strike Eagle 1-6×24, which provides fast target acquisition and usable magnification under $1000.
