    How is the M4 different from a standard 16" ar15 carbine? Why are some rifles called "M4gerys?" Thanks.

    The M4 used by the military has semi and 3-round burst only. No longer fully automatic like the M16/M16A1/CAR-15/etc.

    Since you cannot purchase a M4 due to the '86 machinegun ban, the only way to get one is make a forgery. Those that can't have full auto or collapsible stocks make an even worse forgery.

    The idea is to have a civilian legal carbine that mimics the Army's current issue carbine as closely as possible. You can not easily or cheaply have the exact carbine for a couple reasons: The Army's M4 is select fire, the Army's M4 has a 14.5" barrel, if you are using a post-ban lower reciever you also can't have the flash suppressor or the collapsable stock.
    So, you end up buying an upper reciever with a 16" barrel: 16" including a muzzle brake made to look like the military issue flash suppressor. The barrel will have a portion just in front of the front sight that is smaller diameter than the rest of the barrel; on the real M4 this cut-out is for mounting an M203 grenade launcher. On yours, it is for looks. You get either a fake collapsable stock or buy a pre-ban reciever so you can have the real thing. Oh, and you want a flat top upper reciever.
    So, we call this a forgery or M4orgery since it is not the real thing, but is as close as we can easily get without jumping through a whole lotta hoops or breaking any laws. In the end you have something that looks very close to the real thing.

    Lemme see ... not sure hor accurate this is, but off the top of my head, the trigger groups for M16 series rifles are something like this:

    AR15 - safe/semi/auto
    XM177 E1/E2 - safe/semi/auto
    M16 - safe/semi/auto
    M16A1 - safe/semi/auto
    M16A2 - safe/semi/burst
    M4 - safe/semi/burst
    M4A1 - safe/semi/auto

    Keep in mind, this ignores all the other differences in the rifles.
