Pistol AR I had with no brace was a range lawyer magnet. I could see me running into a know it all who disliked the gun, my explanation of legality, and my generally dismissive demeanor towards idiots taking the opportunity to call Johnny law to come talk to me. And in some localities that wouldn't work well. Yes, no brace and I had numerous people tell me how wrong I was.
Next SBR will have a can, da switch and whatever other pearl clutching devices or I won't bother.
