no offense but I had an SKS and sold it because it was a crap gun couldn't hit anything with it past 100yds and I have a an AK which shoots the same round as an SKS 7.62X39 and I can actually hit paper with it open sights out to 250-300yds no problem
Sounds like you had a shot-out barrel. I have quite a few SKSs and all of them are far more accurate than the AK patterns I have owned. However, they are definitely not a substitute for an M1 Garand (I have one of those as well). SKSs are a bit more rugged than the Garand (At least my SKSs have held up in worse weather/mud/muck than my Garand) with cheaper ammo. But the M1 is an M1, and it's definitely more accurate with a powerful round. I say buy both.
