Hehe, the AK47-S is the AK with a sight on the CF. Of course, that sight exists in real life, so I have one. This reflecting sight has no magnifying function, and the model is BSA. It has a one-to-one perspective, that is, the objects outside are as big as those inside and will not shrink. There is also elevation angle and wind deviation, that is, adjustment from top to bottom to left and right, which is not as accurate as expected in the mirror.
