Hi this is my knex crossbow. The crossbow has an anti-jam system for the rapid firing. It has a 16 bullet magazine which is quite fast at reloading. An aproxamate speed of firing all bullets is 25 seconds with re-pulling the band back. The gun was based on a model on this site but it has been modded a lot . It has a reasonably good firing range of 13 meters. No accurate sights have been installed but if you look through a certain place, you have a better aim. The whole crossbow has a weight of 1 kilo rounded up but is easy to cary around. The shape is made to be stable on a table , but can also be good if you put it on your sholder. If you drop the crossbow it will not break easily due to its compact build. Please vote and follow me. If you have a 3ds or 3ds xl, i'm happy to trade friend codes with you.
