These are front sight blanks for S&W revolvers. If you are looking for a custom height you can take a blank and trace either type of design (pinned or spring loaded) on these blanks. Then with some machining or filing you can then get a custom height.
These are shipped without the fiber installed but with both Red and Green Fiber rods included.
These blanks measure 0.733 tall and 0.120 wide.
**Pinned and spring loaded sights are pictured to show the outcome after customization, they are not included**
