Ours is weird, feeds fine for first three rounds but can't get the last round to ever chamber. Shoots pretty well though. I just shoot three and leave the last round in the mag.Do the 223s feed reliably? I have a Rem700 that feeds 90% from AI pattern mags. I love it for varmints and flat range shooting but I’m debating a RA Gen 2 that uses AR mags for a field gun.
