To expand further, optics or irons is personal choice and can be tailored extensively to the individual. Some of my friends cant shoot irons worth a damn but do very well with a scope while some are the exact opposite. I have too many different guns to be picky about much of anything other than quality but I prefer irons of any kind inside 100 yds. Also, some SKS do shoot quite well. I remember one member posting 1.5" groups @ 100 yds but this is far from average. The best I would hope for is 3-4 MOA and be happy with 6-8 MOA. I havent seen it but have heard it can be much worse

. Now to the original question: Buy a good quality centerfire scope. NC Star is price-point budget minded products bought in high volume from China to sell at low prices in high volume in North America. They have the typical 3 points going for them: price, looks and features. Quality is spotty and reliability is poor. Your Soviet pig will chew them up, spit them out and rant about it's mother's borsht

As mentioned the new Redfields are a good buy, I believe they are almost a re-badged Leupold VX-2 with classic Redfield looks. Either way theyre good Made in USA scopes backed by one of the best warranties in the business. Same thing with Leupold if you want to spend a little more. For a little less you could go with a Bushnell 3200 or better. To expand on Sadosubliminal's recommendations, the Vortex Strikefire will take a hell of a beating without issues. They go for $175 - $200 depending where you buy them.
