I have been following this website for a while now, but this is my first post. I know how the majority of you feel about gun control and many of you might find this video interesting. I am not sure how many of you have heard of 3D printing. It has unlimited possibilities including the future production of semi-automatic lowers from any home 3D printer. This technology can definitely cause alot of controversy.

The video is kind of long, but if you dont watch it to the end, he mentions that with newer printing materials it may be possible to print whole guns.
