Extreme Lego builder Nick Jensen has been making life-size replicas of weapons from the Halo series for a little while now. For example, last year he made a model of the series' distinctive Sniper Rifle.

Jensen's newest creation, a replica of the M45 tactical shotgun from Halo: Reach, may be the most intricate weapon design in the history of Legos. In addition to being life-sized, Jensen's shotgun has a working trigger, slide, and mechanically ejects Lego shotgun shells.
