Most fiber optic sights require heating and melting to swap the fiber. That means once you install it, you’re stuck with whatever color you chose — whether or not it’s ideal for today’s conditions.
Tag Precision’s FiberLok™ system lets you change fiber colors in seconds — no hassle, no risk of damaging your sight. Just remove a set screw with a hex key, swap the high-temp CNC machined fiber rods, and you’re good to go.
Why changing your fiber optic color can improve your accuracy

How adapting your sights to the environment — and your eyes — can give you the edge.
When it comes to shooting performance, sight alignment and sight visibility are everything. Yet most shooters never consider one of the easiest ways to improve both: changing the color of their fiber optic insert.
1. This is where FiberLokâ„¢ makes the difference
2. Choose your color, control your performance
Each fiber color reacts differently to ambient light — and your eyes react differently to each color, too. That’s why professional shooters often experiment with fiber colors until they find what works best for their environment, their gear, and their visual preferences.
- Green is one of the most visible colors to the human eye and works well in bright, outdoor conditions. It’s a favorite among competition shooters who need speed and clarity.
- Red tends to stand out strongly against most targets and backgrounds, especially in sunny or high-glare environments.
- Orange is often overlooked, but it performs surprisingly well in mixed or artificial light, like indoor ranges, and provides strong contrast without overwhelming brightness.
- Black gives you the opportunity to practice without the advantage of a bright fiber, and then swap back to a brighter color when you leave the range. No changing sights or having multiple firearm setups.
The point is this: there’s no one-size-fits-all answer. The right color is the one that gives you faster target acquisition, better sight picture, and more confidence behind the trigger. With FiberLok™, you can find it — and switch it anytime you need.

3. Customize without compromise
Every shooter has different needs — whether you’re running drills, preparing for competition, or just want to trust your sights in a self-defense scenario.
With most sights, you have to choose: go with the standard look, or take a risk trying to modify your setup. But Tag Precision sights are designed to give you high-end customization without sacrificing durability or aesthetics.
Each sight is CNC-machined from hardened steel, with a QPQ Nitride finish for corrosion resistance and long-lasting performance. The sleek profile integrates seamlessly with your firearm, while the FiberLokâ„¢ insert lets you tune the experience to your exact needs.
No more picking between "cool looking" and "functional." You get both — and the flexibility to adapt over time.
4. From range to real life
A great sight isn’t just about performance at the range — it’s about peace of mind when it matters most.
Whether you carry daily, train for self-defense, or compete under pressure, visibility can’t be a guessing game. Low-light situations, indoor environments, or fast decision-making scenarios demand a sight you can see clearly, instantly — without second-guessing.
FiberLok™ gives you that control. You can start your day with one color and switch it before heading into a different environment — no special tools, no downtime. It’s one less variable to worry about, and one more advantage in your corner.
