*I think North8000 is right here.  If we had a picture of the exact gun, and yes, we likely will have a fair use copy in time, then it would be less problematic, but we are adding original research if we are putting up images that are "kind of like" the gun used.  That alone is enough reason to pause.  Secondarily, we have to ask the question we ask of all photos: Does this add context to the article?  I would argue that the value of the image is very limited.  Semi-automatic weapons of the AR15 class are hardly rare, and the image doesn't add much more than the description does, which being wikilinked, means that anyone truly ignorant of what an "assault" rifle looks like in general can click over.  By adding a gun image that is potentially significantly different in modification than the original, we may be adding more disinformation than information.  When faced with this possibility, weighed against the dubious value the image adds, then excluding an image until the real gun picture can be obtained, or at least an image with a very high possibility of being identical, is the better option. WP:OR seems to be the primary factor here, as it is obvious we don't have enough information to determine exactly what the gun and its modifications look like at this time.  -    Join WER
