So much for the idea that registering and confiscating guns from innocent folks will stop criminals from getting them.

Even if you could magically get rid of every gun in the hands of the criminals, they can just make some on their own.

What are we going to do, get rid of metals?

I hear some can be made of plastic...

In recent months increasing numbers of the model below have been seized, appearing to overtake the previous model in frequency. It is characterized by an unconventional appearance, owing to the use of a tubular receiver and a conical barrel nut. Unlike the majority of ‘T’ SMGs this design does not appear to make use of a telescoping bolt, resulting in a longer rear portion of it’s receiver. ‘Made in the USA’ is the most commonly stamped claim.

Holder counts these as guns which originated in the U.S.

Zip guns have been produced in high school shop classes without the teacher noticing.

Yeah, the left cannot achieve Huxley’s vision without controlling the human mind.

Those pesky serfs never know what’s good for them.

And in places like Mexico, the criminals don't need to make guns, they can just pay some Mexican Army dude to look the other way while they drive off with some of the military's inventory.

Also, you think that people who are in the business of smuggling things, can't smuggle guns too?

I am not a gun person.
But looking at these guns, since they are continuous fire you would not need the accuracy of a one shot at a time gun.
So I would expect it would not be necessary to have a rifled barrell to rotate the bullet.
I would bet most of these guns are smoothbore, and easier to make.
Actually it would make for a bigger bullet spread.- Tom

Also, notice the use of the term "submachine guns".

It is EASIER to make a full-auto gun, than a semi-auto gun.

Is this some kind of a “build it here” “buy it here” program in Brazil?

I mean what’s wrong with the ubiquitous AK-47 series?

a couple of them look pretty nice, I wonder how they shoot.

Some of those show some pretty impressive workmanship. In fact many are better looking than the old WW2 British Sten which was factory built. In the final analysis however, what really counts is functionality and reliability.

Does anyone have a link to the plans?

They remind me of the M3 “Grease Gun” sub machine gun used in WW-II. The M3 was simply made of stamped steel parts and undoubtedly a similar gun could be produced in quantity in small workshops.
