Absolutely!! I've got three of these sights, and I've done everything to them. I've completely removed one of the whole pins (unscrewed the nut on the back of the pin, and pulled out the fiber optic), re-installed a pin, had a fiber snap off on me in Colorado (my fault being careless during some spot-and-stalking) and I pulled the leftover fiber still inside the clear tubing out, pushed it through the little hole in my metal pin, and took a lighter to it to flare out the end and I was as good as new.
