I’ve had a CMMG Bravo 22LR conversion for my AR15 for year or more now. Mine came w 2 mags. Don’t know what offering is today. Really easy conversion: just swap out BCG for CMMG bolt and ready to go (30 sec or less). I’ve used at range several times: several hundred rnds of 22LR, different mfgers. Cycles great on everything except subsonic rnds. No FTF’s, no jams, no eject issues. Accuracy seems as good as 223s I use for range practice. Just thought I’d give it a “thumbs up” in case anyone’s interested.
