DefDist Printed AR Lower - Part III - YouTube


In the first half of the movie it's all about shooting. By the way, the entire gun is not 3D printed but a part called "lower receiver" (white parts around the trigger grabbed with the right hand in the image) is 3D printed. Since this part corresponds to the heart part of the gun, the sale and purchase is regulated in the United States, and if it is to sell in general, a firearm manufacturing license is required, but if it is only an individual making it for private purposes it is illegal It will not.




Exchange the magazine ... ....


Shoot and shoot and shoot.


Although I shot more than 600 shots in a row, the lower receiver never broke.



The test just finished because the bullets we prepared did not end, according to the staff it seems to be OK even more than 1000 shots.



This is the state of printing (modeling).


It is possible for anyone to download this CAD data, more than 10,000 people have downloaded so far, and more people are getting it via BitTorrent.


Although you can not do anything if you get only the lower receiver, Defense Distributed is thinking about building a system that can print all parts in the future.
