What's the difference between having a rifle and not having one?

There are obvious differences between these two shapes:

Having a rifle is having an obvious butt.

There is no rifle, the traditional stock is removed, and the shell is enlarged, and the shell directly touches the shoulder. This structure essentially wraps the magazine and launching mechanism in a huge stock, with the grip in front and the magazine and automaton behind, thus shortening the length of the whole gun while keeping the length of the barrel unchanged. This is the most remarkable feature of unsupported structures.

Generally speaking, the length and weight of the bareback rifle are smaller than those of the bareback rifle, and the shooting accuracy is higher, but the sight is higher than that of the traditional rifle, and there are still the following shortcomings: First, the shooter's eyes are behind the shell throwing window, and the gunpowder gas overflowing during shooting irritates his eyes; Second, it is not conducive to making full use of terrain features to exert firepower, such as using the right corner to shoot backhand; Thirdly, the rear magazine is often limited by the shooting position, so it is not convenient to shoot at elevation or depression angle.
