    I just bought my first AR is a Dpms oracle it chambers 223 and 5.56 ammo. My question is what's the differences between 223 and 5.56 nato. What is best to shoot when I'm out in the range??

    556 is a higher pressure round than 223. It's dimensions are also slightly different. It is 100% safe to shoot 223 in a 556 chamber but DO NOT shoot 556 in a 223 chamber.

    Thanks yeah my ar rifle says I can shoot both rounds. So u would recommend a 223 instead of the high pressure 556

    Doesn't matter. Shoot whatever you like/can get cheaper.
