Can't get tight groups with fiber-opitc sights. All glare, and no precision.
I have tried, and and ended up painting them black.
If all I used a gun for was self defense and close range shooting they might work fine, but for plinking and shooting at a long distance, not for me.
One of my guns is a 22 SP101, Ruger, and until I made the front sight black, no tight groups.
Just me,,,
