The crossbow's range is still 35+ feet, and it is still powerful and accurate.

Step 1: The Stock

This step will build the stock of the gun.

bof! la natasion escargo la macheti sorry i acsidently tiped in french
Instead of three rubber bands linked together, I used four single large rubber bands that are fairly tight. It easily shoots through paper and leaves pefectly rectangular holes. Another reason I did this was because with weaker rubber bands the last two shots can jam, this is because the bands on there own don't always pull the gear around properly.

 ya that sounds like that would work pretty well, but  mine didnt seem to make that mistake with my rbs, so i guess it mustve just been your rbs i guess... although your combo of rbs sounds alot better than mine :)
