至少25个美国州禁止装置将手枪转换成机关枪。 At least 25 U.S. states ban devices converting pistols to machine guns amid safety concerns.

至少有一半的美国州已经禁止将手枪转化为机关枪的装置, At least half of US states have banned devices that turn pistols into machine guns, following a rise in such conversions. 联邦法律已经禁止1986年以后制造的机关枪,但执法和军事除外。 Federal law already prohibits machine guns made after 1986, with exceptions for law enforcement and military. 拥有这些转换装置可判处最高10年的监禁。 Possessing these conversion devices can result in up to 10 years in prison. 枪支安全倡导者主张制定更严格的法律,而枪支权利团体则认为这些州法律没有必要,侵犯了第二修正案的权利。 Gun safety advocates push for stricter laws, while gun rights groups argue these state laws are unnecessary and infringe on Second Amendment rights.
