ar15违法

Ⅰ 夏普AR158X复印机出现代码L1是什么问题很急

进给开始后，在规定时间进给没完成，你如果董一点话，进维修模式，连续两次按c，暴光。快点按，用调纸张建按14，启动，或16，或01，01启动。希望对你有帮助。

Ⅱ 美国民众可以买到14.5英寸枪管AR15吗

有，但是好像是违法的：
If they are selling a complete ar15 with a 14.5" barrel w/o a pinned
flashhider then they are breaking the law. The only caveat would be if
they are selling them as pistols in the appropriate configuration.

It
could be a 16" barrel with gov profile, I see those alot and if you
dont look closely its hard to tell that they are actually 16" e to the
gov profile.
我不懂枪，不懂为什么一定要16寸的枪内管容才合法。
