When evaluations or comparisons are made with a generic SKS, do most people not realize (or care about) the improved accuracy afforded by a
Tech Sight? Their website is simple to spot with two seconds of Google magic.
The Tech requires little money, no skill at all, and the original rear leaf sight can be re-installed. It only takes some muscle to push in on the internal spring, and pull back to remove the original leaf. A few minutes light hand-filing of the takedown lever's tiny dimple is easy.
You don't need Gandalf the Grey (Lord...Rings) or "iraqiveteran8888"'s channel
to replace it, or to produce a nice cluster of holes almost touching each other at 50 yards.
