Looks good, a bit bulkier than necessary though.

shoots a lot faster than other crossbows i have seen... SO FAR.

knexguy (author)Crossbow7472008-04-02

Ok, I never said it couldn't.

looks interesting...... what does it shoot?

it shoots Grey rods with a orange connector/ brown on the end i will sharpen the rods some times and from a yard back it might stick in the card board if straight and good shot
