Found this - possible to make?

Does anyone remember Philip Luty and his notorious crude submachine gun designs? I just found this and it looks like he made a semi-auto version of one of his SMG designs. Just looking to see some opinions from some gunsmiths (not a gunsmith myself) on whether this design is feasible, since it looks like a closed bolt design (which I believe for you Americans is legal to make) and that Luty never got a chance to make this design before his arrest.

I am in no position to make this since a) It illegal to manufacture where I live without a special license. b) I have no machinist/gunsmith experience, nor would I have access to a milling machine or lathe.

Are you an BATF employee

As a gunsmith:

From a quick once-over, it appears to be a fully functional, if somewhat simple, design. Being that I have no interest in making it I cannot say for certain that it would function, though from the design it appears to have that ability.

I hope I helped.

crossrhodes,

If he were a BATFE employee, he'd have access to a functional model of this firearm, most likely. From what I've seen/discussed, they have just about one of everything, including home-made designs such as these. That aside, what does it have to do with the question? The firearm in question would indeed be legal as a hammer-fired semi-auto closed-bolt pistol, as long as the barrel were either rifled, or 18" minimum length with OAL being 26" minimum.

The images are pretty crummy and mostly only show parts from one angle. Looks like it'd work, but I'd want better schematics before I made the call on this one.

Not a gunsmith but, where is the disconnect? It looks like it might not reset the hammer/sear if the trigger was held down. I can't say if this would result in semi or auto operation but most common semi autos have a disconnect to keep it one shot per trigger pull.

Didn't look too closely, but it could be a KT type slip trigger bar, where it literally falls off the hammer until reset.

Just checking so don't go geting your cleaning patches in a bunch....said with humor.

It's a dowel on the hammer that pushes the trigger bar down when the hammer falls. Took me a little bit to figure that one out, too, with the *ahem* quality of that "schematic".

A little more detail on things like the bolt,extractor, ejector would be nice, but doable if you want to take the time to figure out the rest of the stuff.
