New Fully Automatic system

for the past 2 days I've been working on a new fully automatic mechanism, and heres how it works. This new system uses a 'Rack and pinion' which starts off with the pinion pulling back the firing pin until it has no more teeth to grip to the firing pin with so it lets go and the firing pin goes flying forward shooting the bullet. after this the firing pin is returned back to its original position it is ready to be pulled again, this all takes around 2 seconds. Range: around 15ft(Blue rod) Firing rate: every 2 sec remember this gun is only a prototype so suggestions are welcome (needs a hopper), and remember that this gun only uses a weak motor so if you were to use a motor like the one a on oodalumps machine gun and with that you could possible double the range and firing rate! Enjoy:)

hey I have made a fully automatic knex gun that works with a totaly diffirent system that is never used before on a fully automatic one. So would you plz tell me wath you think about it ??
here is the URL:

about the motor, it wont double the range because it just pulls the mechanism back faster BUT you could double the rubberbands and then it ould help by shooting faster WARNING if you get the silver or blue motors they will click under the load and will not work!!!
The blue (or black) motor will ABSOLUTELY NOT click. They are INSANELY powerful, but INSANELY slow. They have 20 rpm.

Ah, I wonder why they were special
They aren't special, but the silver version of this motor (Looks EXACTLY the same, but colored silver) are pretty fast, but so weak. It can barely drive a K'NEX CAR!!!
what about green motors?
