American-180是一种非常有意思的冲锋枪。它发射0.22英寸LR口径的边缘发火式枪弹,因此威力和射程都极小,但射速却极高。设计此枪的目的本来是希望高射速和高命中率能弥补威力弱的缺点,但事实表明这只是一厢情愿而已。 American-180 is a very interesting submachine gun. It fires 0.22-inch LR-caliber edge-fired bullets, so it has very low power and range, but a very high rate of fire. The purpose of designing this gun was originally hoped that the high rate of fire and high hit rate can make up for the shortcomings of weak power, but the facts show that this is only wishful thinking.
