these are really cool you can make two and have a battle with your bro'.
Step 1: Handle and Trigger
oh and on pic 6 make 2 of them
and in 11 and 12 thats duct tape it holds that bit so its stronger but you could use sellotape
Step 2: Handguard and Barrel
In pic 2 make 3
In pic 3 put in the blue rods
in pic 4 do the same
Step 3: Barrel
Step 4: Bands and Loading
MORE DUCT TAPE IN PIC THREE ,MAKE IT THE SAME LENGTH AS BEFORE
To load put the band on the black arm at the front and pull it back to the cog and place it on one of the double green connectors then pull the cog back one place and repeat the process til you have roughly 8-14 bands (depending on how many you have). then pull the trigger a few times and the bands should come off.
if it doesent work post a comment and maybe i will be able to help you.
