do they sell Delrin spools for F3s? and if so, is there a place that sells them for a good price?

 

delrin is a "self lubricating plastic" i know it is used in a lot of paintball equipment where 2 surfaces will e rubbing together a lot, such as the bolt where is moves back and forth at a very high speed. it is mainly use in instancees where friction plays a big factor in the performance. but with my experiences with the paintball products, it can be pretty fragile and break kind of easy.
