So I searched crossroads of the west, Costa Mesa, google, and finally calguns to no avail for an answer. I wanted to take my S&W AR-15 to the upcoming gun show to #1 Have a smith remove the damn castle nut that i can't remove without fear of destroying my black beauty, #2 mount accessories on my rails to see if I'd like to take stuff home with me... Thus the questions, am I allowed to bring the rifle, how, and should I? Any insight is greatly appreciated. 
Also this thread is now an generic Costa Mesa pump up thread.
