If someone is unfamiliar w/ the internal workings of AKs then only showing bolt pictures will not make it obvious. For example, lots of people I work with (have shot my guns many times) wouldn't be able to identify an AR from close up pictures of its bolt yet all of them would from a full picture.
That kind of threw me off a little too but I recognized the ak internals.Didn't know they made left handed m92s! Lol
