i'm thinkin' i wan't to install a peep sight on my cva hawken, but i don't see one listed. does anybody make one for it, or does anybody now which one will fit with a little enginering. the cva has a short tang vs. the T/c hawken long tang, so i don't know if the one made for it will work. and it would be better if it was mounted on metal anyway, at least it would be more stable.
