Opinions Wanted!! Im looking to have an AR built for night hunting. I'm currently shooting a 18in Rock River suppressed. I tend to walk several miles a night, and I'm looking for a shorter barreled, lighter AR. My main concern is accuracy and reliability, and weight. I will be shooting suppressed, and I'm not sure how short of a barrel I can go too without sacrificing accuracy? Tax stamps for sbr's don't scare me. Most of my shooting is less than 150yds, but out here in the plains I would like to still be accurate out to 225-250yds. I'm limited to any 22 cal bullet due to state regs. Any thoughts or suggestions would be appreciated.
