As I recall those were not regular soldiers but rather competition shooters, nobody would let some grunt start switching sights around. The whole article was in Swedish language, but a Swedish GB member was kind enough to translate it for us. Also, it does depend on how deep the V-notch is. Take the m94 carbine for example, it's awful, the '95 Chilean is almost as bad, way too shallow. Now, while I have not seen an all-original matching m96 with V-notch in the wild, long time ago, at a gun store, I did hold a sporter in my hands that still had the original sights intact. The front was original barley corn, and the rear Vee was matching to the rifle. I did spend short time studying what was left of the poor thing and even took some pictures of the sights for the future reference. Those photos are long gone unfortunately, but if I ever see one again (highly unlikely), I'll know exactly what to look for. Thinking back, I should've bought the dang thing, it even still had half of the original stock, but unrestorable, tapped for the scope, welded bolt, all the usual Bubba tricks... Back then, I knew that was rare, just didn't realize how rare... Anyway, those sights provided a very nice picture, so I can see why some target shooters would prefer them.
