5.56x45 Ammo For Sale

Eugene Stoner developed the 5.56 NATO in the 1950s for the AR-15 platform, officially adopted by the U.S. Military in 1963 as the standard infantry cartridge. Its lightweight, high-velocity rounds allowed soldiers to carry more ammo without sacrificing effective range or accuracy.

Today, it's one of the most popular cartridges because of its low recoil, cost, and excellent accuracy, even in the hands of a relatively new shooter.
