Is that a machine gun you have there?

(b) Machinegun

The term “machinegun” means any weapon which shoots, is designed to shoot, or can be readily restored to shoot, ⁣ automatically more than one shot, without manual reloading, by a single function of the trigger. The term shall also include the frame or receiver of any such weapon, any part designed and intended solely and exclusively, or combination of parts designed and intended, for use in converting a weapon into a machinegun, and any combination of parts from which a machinegun can be assembled if such parts are in the possession or under the control of a person.

(3) The term “firearm” means (A) any weapon (including a starter gun) which will or is designed to or may readily be converted to expel a projectile by the action of an explosive; (B) the frame or receiver of any such weapon; (C) any firearm muffler or firearm silencer; or (D) any destructive device. Such term does not include an antique firearm.

In VanDerStok, the ATF is arguing that the term may readily be converted was not defined by congress. This makes it ambiguous. An ambiguous term is normally clarified by the rule making procedures.

The gist of the argument is ATF determination letters regarding classification of things as hunk of metal or receiver has always focused on the term “readily”. According to the ATF, the new rule merely clarifies that “readily” can be modified by the auxiliary components included with a kit or in the same purchase.

When asked if the ATF could just as easily claim that all AR-15 lower receivers are machine guns because they can be readily converted to M-16/M-4 receivers, the ATF responded that AR-15 receivers are not being restored because they never were.

The issue is twofold, first, we don’t trust the government. The second is that there is zero difference between an 80% AR-15 lower receiver and an 80% M-16/M-4 lower receiver.

Both require drilling holes for the trigger pin, the hammer pin, and the selector switch.

Both require milling out the fire control group pocket.

The M-16/M-4 lower receiver requires one extra hole.

The Pivot pins are 0.250 +0/0.003 below the deck. The hammer pin is 0.375 +/- 0.002 below the pivot pin. The trigger pin is 0.3140 +/- 0.0015 below the hammer pin and 0.8430 +/- 0.0015 to the rear. The selector is 0.2250 +/- 0.0015 above the trigger pin and 1.9680 +/- 0.0015 to the rear of the hammer pin.

1.9680 +/- 0.0015 to the rear of the hammer pin and 0.4980 above the hammer pin is a 0.1250 +0.0015 -0.0000 hole.

This hole is the difference between an M4 and an AR15 lower receiver.

If the ATF considers a piece of edgedetched steel to be a machine gun, and they consider a hunk of aluminum with a jig and instructions to be a receiver, what would stop them from deciding an AR15 receiver is an M4 receiver?

    only thing that stops gubmint is We the People…. and in “gun culture “ We the People are few and far between. gun owners are far too busy trolling on “social” media and playing “yer gun is junk” games to worry about gubmint…
    complacency breeds failure and gun culture has been failing for a long time. I don’t know if we can turn the Country back to pre obammy days cause it will take each and every one of us. gun nutz brag theres “200 million gun owners”…… just IMAGINE if all 200 million got off their ass and VOTED for Freedom… Imagine if gun rights groups had 200 million members… nah, its easier to troll other gun owners on social media ….. shiite. without firearms none of the other rights will matter. THAT is why gubmint liberals want to ban them. rant done..

    These technical issues typically confuse about 50% of the gun owners out there.

    What stops them? Perhaps they haven’t thought of it. Or perhaps they don’t yet believe they could get away with it.

    There are more differences in the receivers for an M16/4 vs AR15 than just the hole. You need to look at the FCG pocket, at the back. There are 2-3 style cuts back there, only one of which will work as an M16 or with a DIAS.

  6. Mike, the FCG pocket for an AR15 and an M16/4 can be the same.

    Some AR15 receivers have a shelf, some do not. Yes, the cuts need to be there for it to function as an M16/4 but it is that little hole that makes a receiver an M16/M4, according to the ATF.
