For now, because of the gas operated system the empty cartridges are ejected.
That too is because it's an AK-47.
The piston operates without causing misfires or jamsbullet jamming (because the combination of parts had room to spare) even when shooting cheap non-brand-name cartridges or cartridges whose powder had deteriorated from moisture.
But there's no way I can be satisfied with that.
In order to perfectly display its power, I spent time looking for the optimal distribution.
The thickness of the cartridge, the burning impression in the amount of powder, the properties of the bullet core, et cetera—all of these are still incomplete.
