The SKS is a good, battle proven rifle, having served in the final campaigns of the Second World War, Korea and Vietnam. If you go with an SKS, you are making a good decision.
I rather like the Marlin 30-30 lever action rifle, available at Big 5 on sale every few weeks. It's a good rifle, and is very handy, but it is not my first choice.
For me, I bought a beater truck gun a couple of years ago that I have just fallen in love with. It is ugly. It is dinged up. It is durable. It can hit a man at 500 yards. It will cut through sheet steal. I like my M44 Mosin Nagant. It has become my go-to gun. Yes, it is not a spray and pray gun, but it is fast to load with stripper clips and it's 100% reliable. I like the Mosins.
If you have the option, get both the SKS and the Mosin. You won't regret it. I would advise you though, practice with it. A man must know his gun.
