Modded Knexfreek "the Final Stand"

i have modded "the final stand" with a stock, big and small wheels, and a loading arm, it is a very reliable gun, and i love the ability to rapidly fire with the loading arm, but you can't use rubber bands on the mag pusher, it just wont work the bands get stuck, any suggestions? So put tape around it, and push it up manually when ready.


i have now posted following pics of V2.0 Its stronger and Shoots harder.
