SOO... here's what ya need...
-One Nerf Night finder (preferably modded, I added a BB gun spring)
- 2 pins (at least one)
- 2 Rubber Bands
- Scotch Tape
- Air soft BB's
- A Nerf dart (can be a Stefan or old dart)
- Drill (small bit)
- Yellow or longer knex piece (or something you could use as a ramrod)
- TARGET (preferably human, heh heh heh >=D)
This is the harder version, receiver 545 made an easy one
