3D printed guns are not only a controversial subject but a growing one, as innovations continue in that area. Recently, PrintedFirearm released a short clip of their new creation — the 3D printed AR-10 (CM901) lower receiver, which is a powerful piece, firing 7.62-millimeter bullets — and apparently without issue. The 3D printed lower is also a modular design which allows it to shoot 5.56-millimeter rounds as well.
