I was referring to the other options like a receiver cover that do need to be removed.
One of my favorite parts of the SKS is how fast you can reload it with stripper clips, and Im sure I am not the only one who loves this feature. If thats not one of the reasons you love the SKS, then by all means slap a rail over it. For this reason my SKS will probably not get a real scope unless its a small red-dot or something. Although I really liked the looks of that new SeeAll sight, it could be a nice fit on a scout mount methinks.
From what I've heard, this is the best option for a regular scope, because you have a huge range to mount it so eye relief can be just right... Which is another problem with receiver cover mounts, you can't mount the scope far enough forward (or so I've heard, again dont have one but I have researched extensively enough to realize its not for me.)
