Hi,
I first really liked the SKS, came to doubt it, and then, after listening to a bunch of people here, bought one from another member.
And I ended up loving it! A commercial refurb from 1951 in a laminate stock, with an immaculate bore that is not chrome lined. Sure, the trigger is heavy with a lot of creep, but it breaks clean and consistently.
It shoots pretty well - 1" to 1.5" groups at 50 yards. Ammo is pretty cheap (even non-corrosive), and it's a blast to shoot with aperture sights.
The damn thing is built to last and it's simple to operate and break down for cleaning. I can't speak to the vast majority of them, but I will say that a good one is a great bush/truck gun.
It's a working person's rifle and to me, deserves a place in your gun safe if you like the 7.62x39 cartridge.
Cheers,
Neil
