3D-printed rifle fires three shots, designer claims up to 14 – The competition for most successful 3D-printed firearm has moved to Canada, where a man known only as “Matthew” claims to have designed a 3D-printed rifle that withstood 14 shots. In a YouTube video published last Friday, the rifle is fired successfully three times before a text screen claims it developed a crack in the barrel after firing 14 total shots.
