I bought a Norinco in 1990 for $80. I mean, what true gun looney could walk away from an $80 carbine? The original wooden stock was made for someone at least a foot shorter than I (I'm 6'4"), so I put a Ram Line plastic stock on it. It works very well and actually fits me. The accuracy is somewhat better than the AK, but not much due to the horrendous trigger, but it does run without issue with every type of ammo tried. In the last 22 years the eyes have gotten older and the open sights have become harder to use, so last year I experimented with a few things. The previous poster was correct about mounting a scope on the dust cover. It's pointless. However, there is a scope mount that fits into the rear sight block, but allows one to re install the open sight at will. I found that there are no quality scout or extended eye relief scopes that would fit and allow proper ejection of the spent round, and all of these scopes affected using the stripper clips for reloads. It does however allow the use of a red dot sight without problem, so I mounted a Vortex on it and it has worked fine. The mount doubles as an open sight if you remove the red dot, and you can sight it (the mount) in prior to mounting the red dot, then use the red dot adjustments as required to zero. The link for the mount is here:

I bought a second Norinco SKS last year, just because I wanted a second for spare parts should I need them, and the price was considerably higher, on the order of $300. But, adjusted for inflation over 21 years, it actually cost the same, especially if you break the price down in ounces of gold or silver, but I digress. On this SKS I decided to try a peep sight that mounts through the rear dust cover pin holes in the receiver. It also works well, and gives you good eye relief and all of the advantages of a receiver sight, for those who are familiar. You do have to remove the barrel mounted rear sight, but again, you can replace it when you want to. The link for these sights is here:

Here are two options for those who think that "bubba-izing" milsurps is sacrilege may use to enhance the "shootability" of the SKS, without permanently destroying its original configuration. It worked for me. YMMV.
