AR and AK are good to go at Davis. No steel core or 50mm though. Min shot is 25 yrs for rifle and you have to shoot seated from bench. Min 10 yrd for pistol and you can shoot standing or seated. Believe they keep min yrds long to ensure shots make it all the way downrange. I don't work there so don't hold me to any of this, lol, but I believe info is correct. Personally, I'd rather shoot outdoors but never had any issues at Davis. Haven't been to Masterclass yet.
