My Knex Bow and Arrow- Capable of Melee Combat

This is my first attempt at making a bow and arrow. I had to sacrifice my AR-4 Commando v2 for this (long live the AR-4 commando!). This is actually a compound bow, but it just doesnt look like it because of the reinforcements on the front. Its not the best, but its the first bow and arrow i made, so i guess its a decent one.

This bow uses a barrel found on pistols/sidearms to hold the bow. The handle is just below it.

PROS

-20 foot range
-very comfortable handle (even has a split-finger rod)
-uses the least parts of all my creations
-pretty realistic in terms of loading and firing
-decent for melee combat (has blades on both bows, and the reinforcements protect you hand)

CONS

-the arrow spins in midair
-sometimes, the arrow connector breaks from the stick, however, i think this is fixed, if not, its greatly reduced......
-not that powerful

This will be posted soon.
