I think I've found my sources for barrels, but I'm looking to see if anyone has a cheaper option than buying a brand-new Ken Light/Bomar sight assembly. Does anyone have any sight set that's suitable for a 10" Contender barrel in a taco hold?

go here http://www.daisysights.com/prices.html. steve has a taco hold front sight set that works well with the t/c. if you use a williams rear sight you will need his williams rear sight spacer.
