Meet the new 3D printed rifle

posted at 11:59 am on August 8, 2013 by

The thing can fire off 14-rounds (albeit musket Morgan style). ATF and Eric Holder are about to have a snit fit.

Holder would probably classify that as fully automatic.

“Grizzly” is a bit of a stretch for the name of a .22.

But “Tabby” doesn’t quite capture the imagination.

I can’t wait until all the laser-sintering patents expire, freeing the market to produce low-cost 3D printers that can print in metal. At that point, it’ll become awful hard to enforce all those manufacturing bans…

Over a gun that has to be loaded like a musket?

What idiots.

Big deal. Buy one of those little lathes from sears and you could make something nicer than that.

Lathes are next up for DHS.

Lathe control!

It’s like the first calculators of the 70′s or PC’s of the 80′s. Within ten years these things will be something to behold. The train has left the station and it’s not stopping.

Danged Rimfires!!!

sort of like a zip gun made from a car radio antenna.

Given that they want to totally disarm us all, they have to stop something like this in its early stage.

Exactly why the Dems are afraid of this – its just the first step.
If this follows the computer technology path, in 10 years we could be printing up a fully capable AR.

TexasDan on August 8, 2013 at 12:11 PM

I thought it was either a .32 ACP or .380 ACP – at least the first pistols were. Regardless – “Grizzly” is still a bit of a stretch. Maybe “‘Lil Cub”.

Oldnuke on August 8, 2013 at 3:53 PM

Exactly. Its mechanism (what there is of it) is basically that of an 1890s “bicycle rifle”, which it resembles;

http://www.quackenbush.com/hmq/hmq.html

The barrel-removal loading system is that of the CIA “Deer Gun” of the 1960s;

http://en.wikipedia.org/wiki/Deer_gun

Keep in mind, that the objective of such a weapon in an insurgency is to terminate a government soldier, and take his weapon and ammunition. After which, the “zip gun” is passed on to another guerrilla, to repeat the process.

So what if it only holds up for 10-15 rounds? That’s ten to fifteen less government soldiers, and ten to fifteen more guerrillas armed with serious combat weapons.

The mathematics of insurgency tend to favor the insurgents.

Watching this, and other videos, I am struck by the feeling that I am watching a latter-day Orville Wright get a collection of ideas, bicycle parts, and ingenuity off the ground.

… And we were on the moon less than 70 years later.

To be called a rifle, it requires rifling in the barrel. You know, the swirled raised ribs inside the barrel. This makes the bullet spin.

Pressure and heat from a round should decimate plastic ribs made by the 3D printers which use plastic as the material, and easily melted type of plastic at that.

No rifling in the barrel means it ain’t no rifle, just a longer barreled gun.

Kermit on August 8, 2013 at 11:47 PM

Rifling is done with grooves cut into the inner surface of the barrel – not raised ribs.

Precisely… This and the printed AR receiver before it are the equivalent of the Wright flyer… Short initial flights, but great things on the horizon…

PointnClick on August 9, 2013 at 9:38 AM

Would have liked to have seen the impact of the bullets. Muzzle velocity seemed very low. Can it take down a man?

Ted Torgerson on August 9, 2013 at 9:56 AM

Video has been taken down….
