Depends. What is the caliber of the AR-15 rifle? If it marked 5.56, yes. If it marked .223, no. While you MAY fire 5.56x45 ammo in a .223, they are NOT the identical cartridge, and it is not a good (or safe) practice. .223 ammo can be safely fired in a rifle chambered in 5.56 mm. The 5.56 chamber is cut a bit longer than .223 to help insure operations in the field in the presence of dirt, etc. 5.56 NATO ammo is also loaded to a higher pressure than .223. So- to recap- 5.56 in a .223- NO. .223 in a 5.56- yes.
