Here’s your “not quite accurate”:

[Ex gun maker.]

Nope, that is a SEPARATE fixture, NOT included as part of the drawings/tools used to LEGALLY COMPLETE an AR-15 type lower receiver.

There are legitimate uses and users for them, if some fool mis-uses one to illegally modify an AR-15 into an M-16 that is their mistake.

So I stand by my post, the last point of your original post is inaccurate unless someone commits a seperate illegal act.

Of course there is also the little fact that the entire NFA-34 is clearly unconstitutional, making the discussion moot.
