I've been looking into getting a new sight for my sks to replace the rather crude rear sight. I've got the crapco setup on mine(Before you complain about ruining a classic, it was the cheapest was to get a "Assault rifle" when ak's were still over $1000) , and I had the replacement gas tube fitted by a gunsmith, and I don't see even the slightest bit of wobble. I've heard about the gas tube rails being unstable for mounting an optic, but I have no experience with rails. I've narrowed my choice down to either an inexpensive red dot($30-$40), or tech sights (http://www.tech-sights.com/sks.htm). Which one would be a better buy? I've never used either type of sight before, but I've heard that tech sights are far more accurate than the current irons and the TS200's are adjustable for range, and that red dots are better for fast acquisition and low light, but I think It'd sit too high for me to have a cheek weld. I don't have too much trigger time with my sks, since I got it a few days before newtown so I didn't put many rounds through it before ammo skyrocketed, so I don't know much about it's range or capabilities, and that's why I'm here asking you guys, which should I purchase?
