Normally the caliber is 5.56 x 45mm, which is very similar and I say basically interchangeable with another round called the .223 Remington. But other people will say that these rounds are not interchangeable because of different levels of gunpowder in them and different thicknesses of the brass shell case.
But AR-15 type rifles come in many calibers, although none are even close to the popularity of the 5.56mm / .223 caliber. The less-common calibers are 7.62 x 39mm (the round that the AK-47 uses), the 9mm handgun round, 6mm, 6.8mm, and .308 Winchester (which is similar to and arguably interchangeable with 7.62 x 51mm military ammo).

Is 7.62 the same as 5.56?
No, the two numbers are clearly different. In a more practical note, "7.62" is the diameter (in millimeters) of a bullet typically fired from a .30 caliber rifle such as a Chinese SKS or Russian AK-47 rifle, while "5.56" is the diameter (in millimeters) of a .223 caliber bullet like the M-16 or AR15 rifle.
