The 350 Legend (9x43mm) is popular for hunting in states with bottleneck ammunition restrictions. At 2300 fps, this is the highest muzzle velocity, straight-walled ammunition available. Bullet weights of 125-280 grain give this round a 150-300 yard lethal range for white tail deer, hogs, and coyotes. See our full selection of AR15 parts to complete your AR Build.
