While a military AK-47 is a true select-fire rifle, many of the semi-auto clones sold today are marketed and sold under the name "AK-47". It's not inaccurate to call them that, just as it's not inaccurate to call the modern semi-auto M1928's "Thompsons".
Molon_Labe, no disrespect, but I had to chuckle... a scope on an AK is like rims and a tail fin on a Yugo.
