I bought this book a cyear or so ago at Borders or whatnot. It features a couple dozen live diorama pictures of 'specop' guys and explains the gear theyre wearing. In some of those pics the guys are carrying this weird AR/M4 type carbine that is really blocky in the receiver area. It sort of looks like a Carbon 15 but not. If anyone owns this book or wants to give a pic a shot based on the crappy description i just gave. Go for it. I will try to eventually figure out a way to take a pic myself or get access to a scanner.
