1) .223 Remington/5.56 NATO

The most popular caliber for the AR-15 rifle is definitely .223 Remington/5.56 NATO due to its lightweight bullet and high velocity capabilities which makes it perfect for long-range shooting in a semi-automatic platform.

This caliber was originally designed by FN Herstal in Belgium during the late 1950s as a replacement cartridge for their aging rifles chambered in 7.62×51mm NATO round which was heavy and had strong recoil making them difficult to handle especially when firing full-auto shots.

Some benefits of using this caliber are its low recoil making it easier to shoot accurately with faster follow-up shots; moreover, since it’s widely used by military forces around the world so ammunition availability won't be a problem wherever you go.

The main advantage of using this caliber is that it has lighter recoil but still delivers enough energy on-target making it perfect for small game hunting as well as target shooting at long range since its trajectory stays stable over greater distances.

4) .308 Winchester/7.62x51mm NATO

Last but not least, we have one of the most powerful cartridges available; The legendary ".308 Winchester/7.62x51mm NATO" round! Its heavy weight bullet makes sure that even after travelling through dense trees or bushes before hitting your prey stops them dead in their tracks providing guaranteed clean kills every time!

This round’s popularity comes from its use in military forces around many countries worldwide due to being built originally during post-WWII era conflicts such as Korea/Vietnam Wars so availability won’t ever be an issue especially if you are travelling overseas where military-grade ammunition may be easier found!
