A buddy of mine asked me to make him a fantasy airsoft "armgun" for his airsoft games. The design we came up with is a 12" long bullpup pistol configuration that uses two identical guns angled in such inside the body that the magazines protrude and form an upside down "V" that the forEarm passed though when grabbing the pistol grip. Trigger mech I am still working on, but it will be electronicly actuated with with three modes of fire: Automatic, Semi-Simultaneous Fire, and Semi-Alternating Fire.

I figured what he hell, I like tinkering and he's gonna pay me. I started taking measurements of his gas glocks, start drawing, looked at the real Glock 17 on my nighstand and started thinking crazy things... Like what if I made this out of aluminum instead of plastic...

So yeah:
1) Two handguns inside one chassis. Is that even allowed?
2) E-Trigger. I know they are legal and used on olympic guns, but I assume i should follow that stupid one bullet to one pull of the trigger rule. Alternating fire of the guns would be safe, but since technically they are two guns with two intact triggers, could it be set that one pull of the E-trigger would fire both simultaneously?
3) There's nothing illegal about a bullpup pistol, right?

I'm pretty sure you will be needing this soon, I would not even want to have what your making in the same house as a real gun that it could work with as that might be constructive intent.

1 - Yes - LeMat revolver, for example:



2 - No - see the non-importable double 1911, classed as a post-'86 machine gun:



3 - Correct - see Bushmaster arm pistol:

Tek, I was concerned about that as well. I mean if it's plastic the thing would probably break under actualy recoil, but I suppose the ATF would only need it to fire once...

uh, for airsoft you can do whatever you want...

not sure when you jumped from airsoft to real firearms, it was kind of hard to follow.

Not sure what your asking here.....if its a real, live bullet shooting, big-kid firearm, than as long as you dont have a stock and its not designed to be shoulder fired, your good.  If its airsoft, then do what you want with it, it wouldn't fall under firearm restrictions.

I guess I could have been more clear. Yes, I'm asking about using two real Glocks 17s mounted  in a chassis with an electronic firing mechanism to make a completely impractical bullpup arm-pistol for no other reason than I want to see if I can. I understand all the common legalities, but the following I was looking for insight on:

1) Two handguns inside one chassis. Kinda like turning two guns into one...Is that even allowed?
2) E-Trigger. I know they are legal and used on some Olympic guns, and there's even a drop in kit for the 10/22. What I need to know is if one E-trigger tripping two seperate firearm triggers in an alternating fashion be allowed? Not a two round burst. I'm talking "Pull - Fire left, Pull - Fire right, Pull - Fire left," and so on.

See the LaMat above for your guidance on #1.  Your scenario in #2 does not appear to violate the premise of 2 or more bullets fired from a single pull of the trigger.

Alternating shots you should be fine, but I would make sure there is no possible way that electronic trigger could be configured to shoot two bullets with one pull or you are looking at constructive intent at a minimum.
