I have a Rem 870 with rifle sights and want to replace the front sight. I want something with a thick blade with a white bead or a dimple I can fill with white paint. The closest is a XS Sight Systems front but I don't want night sights. Would it be expensive to have someone mill one that I can slide into the dovetail on the ramp? I've looked around but not finding anything I like with exception of the Wilson shotgun front sight but only want to use the existing dovetail on the front.
