Life, it's been quite a few years since I have been able to shoot open sites. Even peeps are no longer an option. My long distance vision is still excellent but anything closer than 2 feet is a blur to my poor old eyes. I did a little searching for you and found that you aren't the only one with a site problem with the FX. It seems that Williams setup (front fiber) that comes stock with it is just too big. I ran across this little article that, if you have some basic skills, you can do for your FX and have a MUCH better site system and I BELIEVE is Colorado legal. http://www.gohunt.com/read/skills/in...t-muzzleloader Take a gander at that and see what you think. If you don't think you can do that installation yourself (it isn't hard at all but some people just shy away from stuff like that) then give me a yell about your location and I'll see if there is anyone I know (smiths) that's close to you that will do it for you.
