Knex Team Fortress 2 Scattergun Build

hi, this is my very interesting attempt at building scouts stock scatter gun in team fortress 2 out of knex. the lever does go up and down like it does in the game as well. i know the barrel looks choppy because the dimensions it is built with are very awkwardly put together because this is basically my first time building stuff like this with only a picture to look at .

i'm not sure if i will do a tutorial, since i always add things to it every day

it is kinda flimsy, since it is being connected with a blue rod and those white connectors and a black clip connector. but with light play it does not break.
