Lego Automatic Pistol

This is what the gun is going to look like

You need 11 1x2s, 3 1x3s, 1 1x2 with a clip on top, 2 flat 1x2s, and a 1x2 bar piece *note please use the specific pieces I showed (not the same color necessarily) or else it doesn't work also first two pics are blurry*

Assemble 7 1x2s

Add multiple more 1x2s and 1x4s

Add rest of the pieces on

To load place rubber band in-between the two studs on the tip and around the two studs on the mechanism's 1x2 then to fire release mechanism *note, make sure to pull back the mechanism when loading as letting go will cause it to fire, also make sure to use "Rainbow Loom" elastics*

Thanks
