镇暴霰弹枪是一把由弹鼓供弹的半自动霰弹枪。它的秒伤相当之高，而持续输出也得益于大容量的弹鼓（12发）十分可观。在使用者拥有了霰弹枪医生和击退这两个特技之后，它就成了一把可怕的近距离杀戮机器。尤其，它的换弹速度要远远超过任何其它种类的霰弹枪，这除了意味着它可以随时方便地依据实际需要而切换弹药种类之外，更意味着它带来的恐怖的霰弹雨几乎不会有停顿的时候！It also has the distinction of having the lowest Action point cost of all shotguns at 17 AP per shot which is comparable to some pistols, making it very useful for VATS dependent player characters.
