Double barreled rifle with 1 trigger a "machine gun?"

[JoeTheShooter]

The term "machinegun" as used in this chapter means any
weapon which shoots, is designed to shoot, or can readily be 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.

Wouldn't that go under the part of designed to shoot more than one shot.

I'd say that would be one expensive retina detacher lol

[aplinker]

Yup, MG.

[cmth]

One shot per single trigger pull, otherwise it's an MG. Double rifles and shotguns with two triggers that can fire both barrels simultaneously are not MGs.

[Booshanky]

If one trigger controls both bolts, then yes. If you have two triggers that you can pull simultaneously, then no.

[SJgunguy24]

If one trigger controls both bolts, then yes. If you have two triggers that you can pull simultaneously, then no.

I have an O/U shotgun with only 1 trigger. The trigger needs to reset before the second barrel touches off.

The way I read that is 1 pull and multible shots, yes a MG.
If you reset then no not a MG, by a single function of the trigger, that is what gets you out.
