A: If your AR-15 barrel is rated for 5.56 NATO you can use .223 REM with it. Also, the 1 to 9 twist rate should not be too fast of a twist to properly stabilize the 55 grain .223. Keep in mind, if your AR-15 barrel is rated for .223 RM it is not advisable to feed it 5.56 NATO. This is because 5.56 NATO is rated for higher pressures than .223 REM.
