Sons of Guns (2011)

It's been ten years since Red Jacket Firearms first opened its doors and Will celebrates the only way he knows how: with a seemingly impossible build. Will calls his mentor Tony Rumore who invented a Siamese: a double M16, which shares its gas tube system. Will wants to one-up Tony for fun and build a Triamese: 3 M16's joining in a triangular formation, also sharing the gas system. While Will works on the build, his daughter Stephanie plans the ultimate surprise anniversary bash for her dad, inviting some of Red Jacket's biggest clients.
