take 4 blue rods and attatch them skipping spaces around 5 white snowflakes, but put an orange connector 2 snowflakes in to act as a block trigger. then build a standard white snowflake/orange connector barrel 5 layers thick and a yellow rod long, attatch them together and you may need to mod to attatch to your gun. but to fire, just use a black/grey rod for firing pin and load in random junk (the debris at the bottom of a knex box works well here) or you can load in marbles, rods, and many other things.
