Question

[guardian146.livejournal.com]

This is the first year that I will be bring prop weapons as part of a costume.  So my question has to do with peace bonding them...exactly what are they looking for?  I kinda have a handle on the handguns (i was going to zip tie them to the holster), but my little brother is coming in his SG costume with P90 and i'm not a 100% sure on what to do with it.  It is non working, I've taken it apart and pulled all the mechanics but I still wanna make sure that we are following con policy.  Thanks for any help.
