They are very different bows. I have the Kodiak Hunter and K-Mag which use the same riser, just a difference in limb length (60" vs 52") with maybe a 3-4" sight window, whereas the Super K has riser caps with a much longer sight window more in line with a Tamerlane (which I also have a few of)...large enough for a Bear hunting sight to be added on some of the original models. The Super K was, and is, available with a 64" option from 1967-1970, (Grayling bows) and 2011 and up (Gainesville bows)
