Nick Jensen is a sick man, and I say that in the nicest way possible. After totally flipping out because of how awesome Halo: Reach was, he knew he had to do something big to commemorate. He studied the design of the game's Sniper Rifle System 99 Anti-Matériel in excruciating detail, then he constructed this full-size model of the weapon over the course of four months.
The final beast is over five feet long and weighs over ten pounds. Good gravy, the damn thing is so heavy that the barrel actually sags! Limp biscuit aside, this is quite an impressive project. You can check out some glamor shots of the gun in the gallery, or you can hit up Nick's Flickr for some WIP pics.
