    Does anyone know where I can find a M16 or M4 blueprint with all measurements that can be downloaded?

    I've been searching for about 3 weeks now and all I keep finding are AR-15 prints.

    I, for one, just want to say what a great job the Bureau of Alcohol, Tobacco, and Firearms is doing. You couldnt pay those guys enough for what they do. I dont care what anybody says about them, they are some fine human beings. Say Hi to your new boss for me, and tell Dino in DC that Rob from Boston says hello!

    In a brief search of the net one can find stuff like this.

    There isn't a huge machining difference between the AR15 and M16 but the legal ownership difference is huge here in the US. If someone has the machines and ability to machine an AR15 lower from scratch then figuring out the difference between the AR15/M16 and doing it should be easy. Same goes for the M4/M16 if you can machine from scratch a AR15 you can do a M16 and if you can do a M16 then you can do a M4. All the info is on the net differences are minor.
    I suggest you start with a 80% completed part and stick with the AR15 until you can finish one in the dark and keep all your fingers. :)

    I think your biggest issue is going to be finding them in a file format you can use.

    It'll more than likely be either an IGES or DXF format and these require CAD or a manufacturing software package like MasterCAM.

    These kinds of prints are all over the internet so it shouldn't be too difficult to find them.

    The only difference is going to be the additional surface features for the select fire components which isn't anything even remotely approaching impressive or difficult when manufacturing. Just make sure you have them otherwise you end up with a very unsafe firearm that it just as dangerous to the operator as it is to anyone its pointed at.

    I'm in Baghdad right now. Exactly why do you want these?

    There are only two small operations which would make an ar lower select fire capable. Also, federal prison isn't as fun as it sounds.

    What are the gun laws of Qatar anyway?

    Too much legal talk. The files you want are at www.cncgunsmithing.com Go and learn the laws for where you are, before you make anything, lest you wind up staying at the grey bar hotel with your new roomie Bubba.
