Very good! I have to say, this is the best design for an assault rifle I have seen yet. Thank you for the instructions! I have indeed used these for my own minifig population.
i like your idea! i have some improvements: first try to make ur assalt rifle grey, it'll be cooler. second, instead of using a lego hand use one of those clip on things that lege exoforce robots have on thier hands, those clip things. well nice job it looks good but can be great
