I’m planning on converting a 223 that I just picked up to a 22arc. I do not know much about ar’s because I’m mainly a bolt guy. Just wondering what barrel I should get. I’ve been looking at proof because that’s what I put on all of my bolt guns but I just wanted to get everyone else’s opinion first. I am building this gun for coyote hunting and I am not concerned about weight I also want atleast a 20” barrel.
