在厂家找到了半自动版的图片，全自动的咱们只能看

9mm的 全自动？

羡慕你们可以玩全自动！！！

对，而且后座特别小，很容易控制。这个是AR导气直击装弹（direct gas impingement)结构的。手指把扳机扣到底不放，感觉一眨眼30发子弹就打出去了。我还想多打两次，警察叔叔心痛子弹不让了。

看来就是家里有AR15 还是火力不足啊，不论是警方还是黑帮都有全自动火力。前不久不是抓了个AA女的，说她在淘宝上买Glock的happy switch吗？那个装置就是能把半自动的Glock变成全自动的。不过咱们良民连Google都不要去搜这个东西。严重违反NFA，抓到了就是federal felony，蹲大牢都是10年起的。

司法部真实案例：这个人在深圳买的auto switch只要19美元一个。。。

TOPEKA, KAN. – A Topeka man is facing federal charges after he imported devices from China that for $19 a piece can turn a Glock pistol into a fully automatic machine gun, U.S. Attorney Stephen McAllister said today.

The defendant was indicted yesterday in U.S. District Court in Topeka.

Jacob Gragg, 33, Topeka, Kan., is charged in a four-count indictment with one count of unlawful possession of a machine gun, one count of unlawful possession of an unregistered machinegun, one count of unlawful possession of an explosive and one count of possession with intent to distribute marijuana.

The indictment alleges investigators seized seven so-called “Glock switches” and half a pound of Tannerite, which is a binary explosive, from Gragg. Gragg bought the Glock switches from a company in Shenzhen, Gaundong Province, China. On a website, the company advertised the “Glock Auto Switch,” saying the product would convert all models of Glock pistols to “Full Auto.” The device operates by applying force to the trigger bar to prevent it from limiting the weapon to firing only one round each time the trigger is depressed.

The indictment alleges Gragg was prohibited from possessing the explosive because he had prior felony convictions in Shawnee County District Court and Morris County District Court.

If convicted, he faces the following penalties:

         Unlawful possession of a machine gun (count one) and unlawful possession of an explosive by a prohibited person (count three): Up to 10 years in federal prison and a fine up to $250,000

         Possession of an unregistered machine gun (count two): Up to 10 years and a fine up to $10,000.

         Possession with intent to distribute marijuana: Up to five years and a fine up to $250,000.

Investigating agencies included the Bureau of Alcohol, Tobacco, Firearms and Explosives, Homeland Security Investigations, the Topeka Police Department and the Shawnee County Sheriff’s Office. Assistant U.S. Attorney Skip Jacobs is prosecuting.

仍然存在多种合法连发机构，在vegas 大惨案之后禁掉了一种而已。当然这些附加机构都不能和真正自动机构相提并论，但是仍然极大提高射击效率.
