its hard to understand

benfoxg (author)2008-08-27

you're nerf gun shoot into cardboard at 25 feet (white tiger v2 rifle) and I'm not bleeding from a stupid cheap made in china foam dart going at 7 feet per second. good guns like my m2 and some others can fire at 80+ and 25 feet< god, i've been aroud for a while here and when I here"25 feet" I'm not exatly like "omg!! that's amazing!" and, you don't make nerf guns. you buy them at that stupid little walmart. Last time i checed that's the place the sold a guy a bike and then the quick realese fell off and the wheels where untrue?if you want to argue more, come over to my house you will use your nerf guns and I'll use my knex guns. I'm not paying for your insurance.

Electroinnovation (author)2008-08-31

If you still think this build the reaper. It shoots 200 ft and travels at over 75 mph. Try to beat that with a nerf gun.

g12345389 (author)xiao hawk2007-07-21

lol... That was what i thinking but right now i got some feature but not the more important, semi-auto feature =(

xiao hawk (author)g123453892007-07-21

I just toyed with my Knex for about an hour... and I've run into quite a lot of problems. Anyone have a good magazine design that holds around 4-10 yellow or red rods?

(Note to all those that have no clue what a chinese repeating crossbow (Chu ko nu) is, go to this like:
