And I'll reiterate that any form of text does not belong in a photography contest. Do we agree this is a photo contest and not a lesson in gun recognition? No one needs to know what gun they are looking at to determine if the photo of it is good or bad.
And again I'll suggest that anyone who needs to know what they are looking at can simply send a PM to the gun owner and ask. If, at that point, you're swayed by his tale of receiving the firearm from his great-grandfather who, on his deathbed, swore the AR15 was given to him personally by the Hawaiian King Kamehameha, then, by all means, vote on it. (I happen to think that story is crap, but Gramps said it happened. He was old and dying so maybe he was also hallucinating. Besides, everyone knows Kamehameha preferred an XCR over an AR any day.)
