What are the age requirements for the event? Wanted to take the family but unsure if my 6 year old can attend.

Hey guys... Yea I know, I'm not new here and I hardly post but I'm in a big debate on my next gun purchase which is between an FNH Scar 16s in FDE,  a IWI Tavor in black or a full custom lightweight build with all Battle Arms Development parts(upper, lower, light rigid barrel, sabertube etc.) None of which I shot but held both the Scar and Tavor in store and like the feel of the Scar. The Scar would mainly be for myself if I get it, the Tavor would be for both my wife and I or mostly for my wife because I figure the weight distribution would be easier for my wife to handle and considering a lightweight build for my wife to shoot who is 5ft tall and weighs 100lbs. She already has trouble holding up my LWRC SPR for a full 30 rounds(shot in private land) So yea I need some opinions please or if some fellow 2a'ers will allow us to try their Scar, Tavor or lightweight builds.

Can we preorder or 1st come 1st serve?
