If you are that close, just shoot over the bore lol, you are not using those sights anyway. There is literally nothing redeeming about having open notch sights far away from the eye. It was a thing in the 19th century, and reason it stuck around for as long as it did was because militaries still wanted to train guys using the old techniques and be compatable with older firearms. Russians and other Eastern Bloc folks (who basically just copied the Russian firearms 1-1) were literally the only ones to use that type of sights after WW2. Everyone else realized that aperature is better. Even in Russia, the SVD initially had an aperture because it's better, then they told Dragunov "we don't want to train soldiers for two different iron sights, use the AK sight". And with the AK-12, even the Russians have finally adopted the aperature sight.The optic part is cope, but the irons on the AK are better than aperture sights for close range like when you are fighting in a trench.
Like I said, there is not a single redeeming quality in the AK style open iron sights. They are fucking trash, and no doubt one of the reasons for the fuddlore of AKs being inaccurate. Because who the fuck can hit anything with those sights anyway?
