Why is the top of the 95 rifle so high?

The biggest design mistake of Type 95 assault rifle is that the handle is fixed, and the bolt handle is placed in the handle. The wrong high handle design was adopted in the early stage, which made the aiming device of Type 95 assault rifle rise upward, making soldiers risk their lives to shoot from the exposed area behind the bunker, and the towering cylindrical quasi-constellation is easy to collide with foreign objects when carrying.
