My Marine dad brought an SKS home from Vietnam in 1970. It was recovered from the battlefield where he earned his Purple Heart.
Back then the only source of "30 Russian" ammo was Norma, and it wasn't cheap. The first time I shot it, I was probably 11-12 years old and I was pleasantly surprised by its very mild recoil.
Believe it or not, I took it to school (in Oceanside, California, 1971) for show and tell when I was in the 4th grade. I asked my dad, who contacted my teacher, and she and the principal approved. It sat in the coat closet most of the day, leaning against the corner.
I have that SKS now, and a few years ago I came across a Norinco SKS "paratrooper", which had a shortened stock, short spike bayonet, and shortened, 16" barrel. It's well balanced, reliable, and handles very nicely, about like an M1 .30 Carbine.
