FAQ
Scopes require exact calibration. Our precision set screws provide smooth, stutter-free rotation for windage and elevation knobs, and they hold internal components rigidly in place without cracking the delicate glass under heavy recoil or vibration.
Yes. We apply specialized anti-glare, matte black surface treatments (like precision black oxide) to our screws, ensuring they absorb stray light and maintain the contrast of your optical system.
Absolutely. Developing new optical equipment requires iteration. We are small-batch friendly, offering 10-day rapid prototyping to accelerate your engineering timeline.
