Dukie: you can buy light pipe material *cheap* online. Lemme find a link for you. http://www.hivizsights.com/products/...litepipes.html
Dirt cheap. You might be able to get them for even less in larger numbers.
Oh, here for huge amounts, by the meter: http://www.fiberopticproducts.com/Archery.htm DUKIE & LECHOOCH: I got a whack of spare light pipes with the Novak front. Save yourself the international shipping. I'll send Dukie one of them to work with.
