The Truth About Guns (TTAG) has found another “downloadable” gun platform that can be created on a 3D printer.
The Charon is a 3D printable lower receiver for the AR-15 that combines the ergonomics and solid construction of the PS-90 with the benefits of the AR-15 platform. The files for the part were released earlier today, and within hours the Dropbox account of the author was suspended for using too much bandwidth. But never fear, there’s a mirror of the files available for download. At least, until the DoJ gets wind of this and shuts it down as they did DefCad.
