Three heights. One approach. Fundamentally different.
Traditional sights were designed for the range. NDEX was designed for real life. It removes the front sight post, eliminates the alignment step, and keeps your focus exactly where it needs to be — on the threat. No electronics. No extra steps. Nothing between you and the decision.
DEVELOPED BY TYLER GREY
built from experience
If it doesn’t work under real-world conditions, it isn’t a solution.
Tyler Grey built Saberdyne Systems around that belief.
Not to compete with what already exists. To build what should have existed.

Faster Target Acquisition
Your eyes belong on the threat.
Traditional sights are built around alignment. That takes time, and it takes your focus away from what matters. NDEX removes the alignment step entirely, so you stay locked on the threat from the moment you draw.
Increased Target Visibility
What you can see, you can engage.
Most sight systems place something between you and the target. NDEX opens your visual field instead of blocking it, giving you a clearer picture of what’s in front of you when conditions are anything but ideal.
Natural Stress Response
The range doesn’t tell the whole story.
Under real pressure, the body takes over. Fine motor control degrades, tunnel vision kicks in, and multi-step processes fall apart. NDEX was designed around how people actually perform when the pressure is on, not when conditions are controlled.
Reduced Cognitive Load
Cognitive load is the enemy.
Every millisecond spent aligning sights is bandwidth you can’t spare. NDEX removes that problem from the equation.

Forged in Chaos: A Warrior’s Origin Story

Tyler Grey’s origin story. Raw, real, and worth your time.
Before NDEX, there was a man being rebuilt. This is that story.
join the rebellion
The firearms industry runs on tradition. We respect that. We just aren’t bound by it.
If you shoot to perform, not to impress, you already know what we’re building.
THE SCIENCE
Why threat focus matters more than most instructors teach.
When your body enters a stress response, cognitive load becomes your primary limiting factor. The more steps between you and effective action, the higher the probability of hesitation or error. This is not theory. It is documented, measurable, and consistently observed in high-stress performance environments.
NDEX was not built to create a faster version of what already existed. It was built to remove the step that causes the problem in the first place. One fewer thing between you and the decision to act.
