Rifle 5.56 Ammunition
The 5.56×45mm cartridge was developed in the United States and originally chambered for the M16 rifle. Closely related to the .223 Remington (though not identical), 5.56 ammo is a top choice for AR-15 platforms and is widely used by civilian shooters for range time, competition, hunting, and self-defense.
Freedom Munitions offers both high-quality remanufactured and new 5.56 ammo at affordable prices. Choose from a variety of bullet weights—ranging from 55 grain to 77 grain—and bullet types including full metal jacket (FMJ), hollow point, soft point, and green tip. Whether you're training or preparing for serious use, our 5.56x45mm ammunition delivers the performance you need. Browse our full inventory below and stock up today.
