Thingiverse Cracks Down on Firearm Parts

Thingiverse Cracks Down on Firearm Parts

This is the lower receiver of an AR-15 rifle, printed in fused plastic filament from a digital model that was, until this week, freely available for download on Thingiverse. This component is significant because all other parts of the common rifle can be readily purchased in the open market. A person who builds a working lower receiver has, in the eyes of the state, essentially built a working AR-15.
