Frequently Asked Questions
AR-15 Ammo for Sale
What ammo is used in the AR-15?
AR-15s primarily fire 5.56 NATO or .223 Remington ammunition. Both calibers are interchangeable in most AR-15s, with common bullet weights ranging from 55 to 77 grains. Conversion uppers allow shooting other calibers such as .22 LR, 9mm, and .300 Blackout.
Is 556 or 223 better for AR?
Both work in most AR-15s. 5.56 NATO runs at higher pressure, making it better for defense and duty use. .223 Remington is more accurate, stabilizes bullets quicker, and is favored for precision work and training. A .223 Wylde chamber safely handles both cartridges.
Can you shoot 5.56 in a .223 AR-15?
No. A .223 AR-15 cannot safely fire 5.56 NATO ammunition. The 5.56 round operates at significantly higher pressure and risks damaging the rifle or causing injury. However, a 5.56 NATO rifle can safely shoot .223 Remington since it operates at lower pressure.
What grain of AR-15 ammo is best?
Best grain depends on your use. 55gr is affordable and versatile for range shooting. 62gr offers better performance closer to military spec. For long-range precision, heavier match rounds like 77gr work well. Your barrel's twist rate and intended purpose should guide your choice.
What AR ammo is best for home defense?
For AR home defense, consider 62-grain hollow-point or soft-point rounds like Hornady Black or Black Hills Dual Performance TSX. These balance expansion with controlled penetration. 5.56 NATO offers higher pressure than .223 Remington, improving terminal performance. Avoid FMJ rounds due to over-penetration risk indoors.
What is the most common AR ammo?
5.56 NATO is the most common AR ammo, developed alongside the AR-15 for military use. It suits range shooting, hunting, and defense. .223 Remington is nearly identical but runs at lower pressure. Rifles chambered in 5.56 NATO can safely fire both; .223 chambers should not fire 5.56.
Is 300 Blackout better than 556?
Neither is universally better—it depends on your needs. 5.56 excels at range and velocity, reaching out effectively past 300 yards. 300 Blackout shines suppressed and subsonic, delivering heavier bullets at moderate distances with less noise. Choose 5.56 for general shooting; pick 300 Blackout for close-quarters suppressed work.
Does an AR-15 shoot 556 or 223?
AR-15s shoot both depending on chamber type. A 5.56 NATO or .223 Wylde chamber handles both safely. A .223 Remington chamber fires only .223 ammo. You can shoot .223 in a 5.56 gun, but never 5.56 in a .223 chamber due to pressure differences.
