Double Barrel Knex Shotgun

First off - credit goes to Killerk for the design of the single barrel shotgun and Knextremist for the trigger.

Ages ago i remember Killerk posting a video of a shotgun that he's made, so i found pictures of it and decided to build it. It was very good and rather powerful, so i decided to make a double barrel version of it. 

I ran out of yellow connectors, so was unable to finish the stock. It shot 8 blue rods 33ft using 2 standard UK postage elastic bands on each barrel.
