Replacing your Browning Buckmark’s stock sights with a set of FireSights by Williams will make your gun very happy. However, they can be pretty tricky to install. Follow my instructions and your accuracy will improve overnight.
You will need:
- FireSights model #70231
- A 5/64 hex allen wrench
- Two tiny punches (I used a small nail and a thumb tack)
- A tiny flathead screwdriver
- About 20 minutes of spare time, which will be well spent
1. Make sure the gun is unloaded. Press the magazine release, run the slide. It takes just a moment and could save your life.
2. Use the hex allen wrench to remove the old front sight. Just remove the single hex screw and it comes right off.
3. Put the new front sight on using the same screw.
4. To remove the rear sight, you will have to first remove two things, the hinge pin and the elevation screw.
5. The hinge pin is a tiny pin that is in the front of the rear sight assembly. It can be a pain to remove. I used a tiny nail and a hammer; simply insert the nail and lightly tap it through.
6. Remove the elevation screw and then the rear sight itself.
7. Now that you have removed the rear sight, it’s time to salvage additional tiny parts from the rear sight assembly and the old rear sight itself.
8. Remove the elevation leaf spring from the rear sight assembly. This is a tiny fork-shaped piece of metal that helps the rear sight move up and down. Just put that with the other parts.
9. Look at the underside of the rear sight you just removed. There’s a tiny spring there; that is the detent coil spring. Take that little guy out and keep it safe.
10. Remove the ridiculously tiny elevation detent pin from the old rear sight. I used a thumb tack to just push it out.
11. That pin was holding a tiny, squarish metal part called the elevation detent. Take that out too.
12. Gather up all of the parts you have so far. It’s time to start assembling the new rear sight.
13. Now you are going to install the parts onto the new rear sight in reverse. First put the elevation detent into the new sight, then affix it in place with the elevation detent pin. After that, replace the detent coil spring in the new sight. Be careful with the detent coil spring! If you slip with it, it will go zing! across the room. Not that that happened to me or anything.
14. Put the elevation leaf spring back in the gun’s rear sight assembly. Make sure the two outer tines are upwards and the middle one is downwards against the gun. Slide it back until it is almost overlapping the hole where the elevation screw will go. (Really, I don’t know why we bothered removing it. I guess to prevent us losing it in the shuffle.)
15. Put the new rear sight on the sight assembly. You will effectively sandwich the elevation screw between the gun and the new rear sight. Put the elevation screw in and give it a quick turn just to hold the rear sight in place.
16. Insert the hinge pin. Note how it threads through the new sight. You may need to tap it with a hammer to get it all the way through.
If the hinge pin doesn’t fit, the elevation leaf spring is too far forward; fix this by removing the sight, moving the elevation leaf spring back a bit, and trying again.
17. Tighten the elevation screw all the way down.
You’re done! Take it to the range and give it a try! You will most likely need to use the screws to adjust the rear sight to your liking. Happy shooting!
