Knex Sling Gun

here is my newest gun-- it took me about 2 hours to make and another hour to destroy (all in one day) I was very sad when i was testing it out cause i thought it would go around 200ft but i only got around 120ft =( NO INSTRUCTIONS WILL BE POSTED i took it apart the day i made it

CONS
range
6 layer handle
