Was easy. Watched some YouTube videos on fiber optic front sights. Drilled out the front sight using a 3/64 bit. Used the Dremel to cut out the top to allow light in. Used a piece of leftover fiber optic from the kit I got from Dawson Precision when I bought and installed a fiber optic front sight on a Glock. heated up a box cutter blade and used it to seal the ends of the fiber optic after I slid it in the hole. Works great! Took me about 30 minutes; was very careful and went slow.
Here's some pics:
