CMP .. a.k.a. Civilian Marksmanship Program

[squeeze]

I know what you mean squeeze. I meant that you won't see any recievers that even resemble an M-14 because of the selector switch. Throw an auto sear in an AR-15 that doesn't have a sear block (anything other than colt) and it functions the same as an M-16. The part registered can be the sear, reciever, lightening link, whatever but it is not the actual reciever of an M-16 that makes it full auto. Take a bare M-16 reciever, put an AR lower parts kit in it, and you essentially have an AR-15 with M-16 written on the side cause it won't go full auto. (I know you can't do this.) I have seen AR lowers with a selector stop at FA, but obviously they won't go full auto and the same with HK 94's. I meant that since the parts that make a M-14 go FA are built in to the reciever and therefore you will never ever see a semi-auto with a true M-14 look-a-like reciever. I know how the ATF treats "once a machine gun always a machine gun" I'm talking more about civilian sales. This is the way it was explained to me at least. I'm interested to hear your thoughts on this squeeze?

OK... you're somewhat right, but I think you may be a bit confused.

The presence of a selector switch has no bearing on whether a gun is considered a machine gun or not. Both Fulton and LRB give the customer the option of putting a selector switch on their M14 builds, yet neither are functional. An M-16 receiver is different than an AR receiver in that it has an extra hole for the sear pin - basically the same distinction between a non-NFA AK receiver and an NFA one. Drill that hole in your AR (and do necessary maching) or AK receiver and you've just comitted a felony. A DIAS or Lightning Link are considered machine guns in and of themselves, seperate from the receiver.
