In a redneck-ish way.
AR 15 with iron sights, unsupported, standing at 35 yards shooting .22LR with CMMG Conversion kit.
The pan, the self-healing and the steel targets got most of the ballistic seed (Federal Automatch 40 grains) because feedback is fun. The CMMG kit ran flawlessly through 3 mags (75 rounds) and my only issue is going to be to clean the rifle. In fact, I am going to leave it as a dedicated .22LR AR and maybe buy a couple of extra mags.
