Great, now 3D printed rifles can fire 7.62mm NATO rounds

[Tonylu1595]

 

 

In 2013, Defense Distributed created the world's first 3D printed handgun, the .38 caliber Liberator The following year, they unveiled an AR-15 receiver capable of firing hundreds of 5.56mm rounds without fail. This year, the team has been outdone by a group of fabricators at Printed Firearm who have once again raised the bar. They've successfully crafted and test fired the receiver for a Colt CM 109 modular battle rifle -- the AR-15's badass big brother. The CM109 is larger and heavier than the AR-15 as it is built to accommodate a larger caliber round: the 7.62 x 51mm NATO. 7.62mm rounds fly farther and strike with much more force than the 5.56mm, making them far more deadly. It also means that the lower receiver (the bit that holds all the firearm's moving parts) has to be both heavier and sturdier to in order to handle the increased mechanical stresses and harder recoil associated with using a bigger bullet.

Sturdiness, however, isn't typically the first thing that comes to mind when talking about 3D printed items. The first few iterations of both the AR-15 receiver and the Liberator failed after squeezing off just a few rounds. Getting them to stand up to the rigors of repeated use has required a lot of trial and error. From the image above, the group has obviously cleared that hurdle with the CM109 components (at least for the first few seconds of rapid firing). "It has been fired with little to no issues," the group said in a statement. Reportedly, the CM109 team crafted the component using a commercially-available $500 DaVinci 3D printer.

Well then... This is just great. Kinda old, but still.

Cool.

[MagnetSh0CK]

Only difference in the 3d printing from 5.56 to 7.62 is a larger magazine well, and more reinforcement for the buffer tube... It's been legal to self manufacture guns since 1776 let's not turn this into a political discussion. Good post, little biased.

now terrorists can 3d print their weapons

YAY

[Meladath]

Is anyone actually surprised in the slightest?

I mean at all?

If you are, why? 3D printers can be used to make almost anything... guns are kinda a part of "everything" so ofc 3d printed guns can be made.

[rmac52]

Nope.

The lower receiver is 3d printed.  Most of the gun is not 3d printed.  this isn't really uncommon.  There have been companies for years now that sold polymer lower receivers.  

Also you could buy a cnc machine or water jet and make metal guns.  It's called gunsmithing.  Still easier to just buy an illegal gun if your a criminal.  Until you can 3d print every part of a gun this isn't a big deal.

[Fate]

They printed a receiver, big deal... 

I don't see why you/the article have such a pessimistic view about this.

No they cannot.

yeah but the lower is the registered part bruh. free illegal guns for everybody

[bob345]

only the lower receiver is 3d printed. Other parts like the barrel and firing mechanisms are not. You have been able to buy 80% metal lower receivers which dont need to be registered for quite some time now. All it takes to make these into a functioning weapon is a vise and a drill press, both of which are much more economical than a 3d printer is. There is absolutely nothing to worry about when it comes to 3d printed weapons because there have always been easier, cheaper, and more effective ways to do it with a simple trip to the hardware store. Look up zip guns on youtube, you will either be shocked or amazed at what is out there right now.

Its not free though.  Its still cheaper for me to just buy a polymer lower for like $100 than to 3d print one.

everyone go home.

[KirbyTech]

Awesome, hopefully this will bring the price of guns down. Means more ammo or more guns, both of which are always good.

but its not registred if you 3d print it...

[Real_PhillBert]

Its not registered if I mill it either, what's your point?

Edit: also most rifles in the US are not "registered" in the first place.

[KirbyTech]

So what? Registering guns does little for public safety, look at Canada, we got rid of the long gun registry because registering guns is ineffective and does not increase public safety.  It is a proven thing so don't act like just because you can 3D print a non registered lower that it is now a danger and a problem. Plus neither is a milled 80% lower which is legal to buy.

 

I should add that you can mold a lower as well with sand, propane, pop cans, and styraphone (can't spell). So there is no problem here, move along.

And its not registered if I buy it in Vermont either.  Or if i remove the serial number.  My point is that this is not going to increase the amount of unregistered guns.  I can buy a cnc machine and make a steel lower receiver.  But I wouldn't and neither would a criminal.

[rmac52]

Actually my rifle isn't registered anyway.   Its legal and I have a licence but the state doesn't know that I have that particular gun.

Okay so what the hell is your point then? 

[Real_PhillBert]

I have many firearms, and only one is federally registered. Federally registered firearms in the US are only very specific firearms, MGs, SBRs, and SBSs.

In the US it's not illegal to manufacture your own lower receiver. You can buy lower receiver blanks and all the tools needed to machine them into receivers online very easily. You are not required to register them with a serial number either. The only caveat to it is that you cannot transfer the firearm to anyone else unless you register it with a serial number.

[MagnetSh0CK]

You never have to register a gun you produce and do not sell... The only time any gun is ever "registered" is when it is bought/made from an FFL and the ownership is transferred. Terrorists can't get these guns because 3d printing recievers is expensive and only LEGAL in the United States, we have borders and airport security so they can't come here. Gun rights haven't changed in 200 years, neither has the reasons we need them.

[The Dragon]

That recoil tho

Correct me if I am wrong but the reason for not being able to transfer it without registering it is because they want to lower the chance of someone prohibited from owning firearms buying it? Or am I was off? Sorry don't know US law as well as local.

You realize this doesn't matter right? Terrorists will break laws and smuggle in real weapons from wherever they want. You think a terrorist whose life will end in one plot will rely on 3d printed lower receivers? I don't think so. Terrorists/criminals can and will break laws. Whether they 3d print a lower receiver means nothing. It won't happen in a criminal case.

waiting until they print 300 blackout barrels... I NEED 300 BLK AR'S IN MY LIFE
