I just got my AR yesterday.
And someone told me it was bad to shoot 5.56 from this, or it could of been the other day around and been .223.
I've always thought they were the same bullet.
But should i be shooting .223 like the remington ones at walmart that say .223 on the box?
Or look for ones that say 5.56 NATO?
Here is my gun
Its a Double Star 15 CAR / 16" / HBAR
