As a kid, I'd often snap LEGO bricks together and make crude pistols. They didn't shoot anything, so for added realism, I would go "bang bang". Like I said, crude.
If I'd seen Jack Streat's LEGO gun creations, my head would've explode. Heck, seeing them as an adult is doing just that—ka-boom!
The 17 year-old Streat earned his well-deserved internet fame by designing one-to-one scale working gun replicas made from LEGO. He's parlayed that know-how into a new book LEGO Heavy Weapons, which gives directions to make four working full-scale LEGO guns.
The book has directions for brick versions of a Desert Eagle, a AKS-74U, a Jungle Carbine, and a SPAS combat shotgun. Think of it as a "greatest hits" section of a first-person shooter—but in LEGO.
From what I've seen of the book, the step-by-step directions are detailed—and lengthy. For example, the LEGO Desert Eagle's how-to is around 50 pages long. Ditto for the other brick firearms' instructions.
Streat provided Kotaku with his latest video (above). It gives a look at the weapons in action, as well as rendered (and fascinating) look at how the parts move and interact.
