I had the fortune of going down to DragonCon this year and spending a lot of time in the Armory. Anyone who goes to DragonCon, watches anything with weapons in it, and doesn’t get down to the Armory is missing out. I had many moments of “Oh, so this is what that’s like!” especially around the actual body armor (which I neglected to photograph).
And, yes, there was a functional pink AR-15.
