Do these interchange .223 and 5.56 no problem? My favorite .223 ammo for my bolt is Black hills blue box 55gr soft point. Will that run good through one of these AR's?
Shooting 55g you'd probably do best with 1/8 or 1/9 twist. The colt uses 1/7 and does better with heavier weights. My 6920 hates 55g past 50 yds
