It's not easy to build real life object using LEGO pieces because of the geometrical limitations of the pieces and connection point. LEGO fan and MOC'er W. Navarre did a great job building this awesome sci-fi weapon replica called Rifle 12: Wayland Terraformers. The shaping of the build is really great as well as the color choices on the main body and stock. Grip of the weapon looks also very ergonomic. The ammunition belt is another nice addition. The builder was recently blogged with another great MOC, Mad Max: Run Wild, so be sure sure to check that out too.
