Developed in 1957 the rimless, bottlenecked .223 Remington has become one of the more popular centerfired rounds in the US and is used in a wide variety of semi-auto and bolt-action rifles. Atomic Ammunition's 5.56 NATO Ammo is excellent, no matter your skill level, and presents a great value.
The 5.56 x45mm round was created from the .223 Remington round. While near identical in appearance, there are several differences between 5.56 x45 and .223 Remington rounds, the primary being that 5.56 x45mm NATO is loaded at a higher pressure than a .223 round. While 5.56 chambers are designed for the higher pressure, many .223 rounds are not, and therefore, it is not advisable to chamber 5.56 rounds in a .223.
Designed for hunting, sharpshooting, and target shooting, the 5.56 is fun to shoot and offers very little recoil. Atomic Ammunition's 5.56mm /.223 cartridges offer phenomenal value at a great price. OpticsPlanet is pleased to offer this fine product as well as more great Rifle Ammo from Atomic Ammunition.
