Bulk 5.56 ammo

Bulk 5.56 ammo was derived from the .222 cartridge and officially adopted as the standardized NATO round in 1963. Essentially, 5.56×45 as a caliber came into being because the military was using 7.62×51. Critics believed the larger round was too powerful for light service rifles. Leading to rough recoil and a slower than the desired rate of fire in military service rifles. Today, the NATO standard cartridge is being designated as “M855”. You’ll often find it in stock and available to shooters. We also carry a huge in-stock selection of .223 ammo for sale here.
