350 LEGEND UPPERS

The 350 Legend (9x43mm) is a straight-walled cartridge introduced in 2019 by Winchester Repeating Arms primarily for deer hunting in states with specific 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. The 350 Legend uses a standard 223/556 bolt carrier group but requires magazines designed for the 350 Legend round.

Any 350 Legend Upper Receiver we sell can be configured to your specifications before adding it to the cart.  We offer matched muzzle devices, rails, bolt carrier groups, magazines, and charging handles to make your 2350 Legend Upper Assembly turn key and ready to shoot out of the box.
