Thinking of going to 5.45 X 39 in my OLL. I understand the mags need a different follower to use this round? Can I use these as long as my new upper is SB23 compliant and no "pistol grip" lower? Thanks for any input. c good

You can go featureless; no flash hidder, a monsterman grip, and a fixed stock.
