    What you have to do is that you have to take the little black pieces and attatch them to the frame before attatching them to the magazine.

    I am making something similar to this but with a different mech... Your clip looks like it works better than any I have built for white rods so, if you don't mind, I'll borrow it.

    It worked a lot better! I just didn't use the clip pusher thing. I made a hinged lid to it.

    make a bigger mag, then make it handheld, then it will be too good and can you make a version without the big wheel and the massive motor. i have the red box connected to the motor ,and the grey ones. so plzzz plzzz make.

    instead of the big wheel you can also use the smaler wheel and a normal wheel 2 times,, the mag is pretty easy to mod, just make a copple of mags and put them on top of each other :p

    cool, the wheel is used for making the motor slower and much stronger so if you use just one small wheel it will probably not be strong enough. but you can always give it a try, this is just a concept for an automatic firing mechanism so go ahead and make it better !
