This is a non-functional object based on the Liberator gun by Defense Distributed.

Again: while these objects vaguely resemble weapons, they cannot be used as weapons any more than any other 3d print.
This is a printable version of "The Englishman from the Liberator Variations. Modeled by Bryan Vaccaro.
