3D printed AR lower receiver doesn't meet expectations

One of the more interesting technologies for creating rapid prototypes and other items is 3D printing. 3D printing is capable of producing just about anything you can imagine from implantable cartilage for medical uses, to prototype parts and even weapons.

A project called Defense Distributed has been working on 3D printer files that allow users to create components to build their own guns using a 3D printer. A group of testers used a 3D printed gun part design from creator HaveBlue to produce an AR lower receiver (the lower receiver is a key component of the weapon that receives the rifle cartridge from the magazine) and headed to the gun range.

Unfortunately, it appears that recoil pressure in the completed weapon was too much for the buffer section of the 3D printed lower. The buffer is a section that separates the stock from the upper receiver reports NBC News. The part failed after firing only six shots. To make the failure even more embarrassing, the testers were using ammunition specifically designed for lower recoil.
 
The creator of the part claims to have printed his own and used it to fire hundreds of rounds.
 
While the firearm breaking in half while in operation seems to offer the potential for harm to the shooter and those nearby, the testers say that the only damage the operator faces is that of ego. When the weapon failed, the spring and buffer popped out of the tube and fell to the ground according to the testers.

I find this much scarier:


Whats so scary about it?

- Legal gun owners are not the ones committing crimes...
- Responsible gun owners lock their guns up.
- Responsible gun owners only use them for self defense, sport and/or hunting.
- Responsible gun owners that carry with them everywhere save more lives every week than these criminals and mass shooters kill every year.

It is illegal guns, obtained through illegal means that are used to commit crimes. Banning guns are not the answers, education, safety training, and teaching responsible ownership is what needs to be done.

Don't blame the gun for peoples actions. Remember, criminals and corrupt government prefers unarmed people.

I was with you right up until that last bullet point. Where on Earth did you get that statistic from? You give gun owners a bad name with BS like that.

really? Show me the proof. Personally I think you made it up.
