Where do you get the stiff white/clear rods?

beanieostrich (author)tytiger332011-07-14

I got mine in something called a Starburst Spinner set a long while back =D And your opinion on the gun?

tytiger33 (author)beanieostrich2011-07-14

Pretty nice but i like Seleziona's double blue rod shooting guns better. They just look better but yours has a pin guide and Seleziona's comperly sized gun does not. Now post the reverse crossbow NOW!!
