生产与装备56式半自动步枪的瞄准基线长480mm,与56式冲锋枪的378mm相比高27％,同时该枪枪管比56式冲锋枪的长105mm,弹头初速相应提高了25m／s,达到735m／s,并且弹道更加低伸,因此射击精度更加优良,特别适合射击400m距离内的有生目标,弹头在1500m距离处仍有杀伤力。后来的63式自动步枪,设计初衷就是将56式半自动步枪的精度与56式冲锋枪的火力相结合,其枪 Production and equipment 56-type semi-automatic rifle aiming baseline length 480mm, compared with the 56-type submachine gun 378mm high 27%, while the gun barrel than the 56-type submachine gun length 105mm, warhead corresponding speed increased 25m / s, reaching 735m / s, and the trajectory is more low stretch, so shooting accuracy is more excellent, especially for shooting life targets within 400m distance, warhead still at 1500m distance at lethality. Later, 63 automatic rifles, the original design is the 56-type semi-automatic rifle accuracy and type 56 submachine gun fire combined with the gun
