the thread is about slam fires, not m16 parts.
Slamfires qualify the firearm as a machinegun if witnessed and you are charged for it. You will then have your opportunity to spend a fortune and tell your side of why it was not a machinegun before becoming a felon or doing time.
It
shouldn't ever happen to you, but if it does it qualifies under the policy. One pull of the trigger fires more than one round. I don't think it says anything about intentional design.
Thats a whole seperate issue. Whether a AR becomes a machine gun when the FACTORY installs m16 parts is a whole other can of worms that falls outside the scope of this thread
Well that is your opinion, the federal prosecutor may feel they are exactly the same thing: two firearms firing more than once per trigger pull in felony violation of federal law, and may even cite such a case as case law for references when convincing the jury the charges are valid and showing similar convictions.
Convictions that were upheld even when a firearm would not fire more than one round per trigger pull until agents tried thier very best to create the ideal situations to accomplish that, with special ammunition, primers, etc.
I think you could easily show the simularities of a case where they could not get a firearm to fire full auto until using special primers, and your case where they could not get your rifle to fire full auto again without using special primers.
A good prosecutor could show the jury they are in fact the exact same case.
They would video tap your rifle firing full auto under such conditions and present that in court.
Most jurors would know nothing about primers, various primers positions and seating and what caused things.
You bringin people in to explain it would appear to be trying to get off on a technical argument even though you clearly were in violation of the law.
Jurors knowing little or nothing about firearms would be more influenced by the video taped recreation in the ATF lab of your weapon shooting in full auto. Firing in full auto in clear violation of the law.
