EDIT: All hats have been claimed.
I have some hats, all of which I got for free and most of which have never been worn:
Two LaRue Tactical hats, one khaki and one black, new. BOTH HAVE BEEN CLAIMED
One Knight's Armament hat, khaki with KAC logo on front, M110 logo on back, flexfit size medium-large, new. Can't find it anywhere online, as it's been discontinued for some time. I can take a pic if you need to see it. CLAIMED
One Bravo Company BCM hat, foliage green, new. Like this one: BCM Cover
One M4 Carbine hat, green, worn 2 or 3 times but in great shape and not dirty. I believe these are out of production. Like this one: M4 Carbine Hat
