    nice job, but I have one request.... I've made one, its great, except for the fact I haven't the slightest clue HOW to hook it up to a gun, so do you think you can tell us that, otherwise, thanks

    Simple - on the gun try and have some pieces that have connectors free on top of the gun - put the small green rods into a vertical connector and clip the mag onto the green rod I'll see if I can post some pics - probs not but I'll give it a go ;D

    interesting, maybe if someone just posts a barrel and someone else just posts a handle, we would have a freaking ausome frankengun! (not an insult, just a comment, I like just magazines, I suck at making them!)
