Evenin fellow smithites... I've got a model 669 with the narrow red insert in the front sight.. Any easy way to brighten it up? Awfully narrow area. Was considering getting a Hi-Viz replacement insert and trimming it to length and glueing it on over the insert. Any one done this??? Thanx Stash

Thought about doing the same for my 469 which has a lond dead tritium insert. At the moment I've got some Nitesiters glued in.
