I do very much like the AR15 being accurate and effective, but I would not call it "manly". In fact, I would rate it somewhere in the "least manliest" spectrum.
Also, the K31? I have one and love it. However, if it wasn't imported for our C&R purchasing, it likely wouldn't have even been considered. I would drop the venerable AK as well.
I do agree with the addition of the M1 Garand, the SAA and M60. Those seemed to fit my idea of "manly".
Then again, opinions are like lips and, um... elbows. I, too, don't generally use the description "manly" or "sissy" when describing firearms. I don't mind playing along though.
