Circle-in-Circle Clarity. Engineered for Precision. Made in the USA.

The Ultradyne C4 Sight Combo redefines back-up iron sights by delivering a concentric sight picture that dramatically improves speed, accuracy, and confidence in every shot. Featuring Ultradyne’s patented Dynalign® Technology, this front and rear sight set provides a true circle-within-circle alignment system, offering a faster and more intuitive sight acquisition than traditional BUIS.

🎯 Why Dynalign® Matters

Traditional BUIS force your eyes to reconcile a circular aperture with a rectangular post—while mentally ignoring protective “ears.” Ultradyne’s Dynalign Technology replaces this outdated visual system with a fully concentric design that mirrors your optic’s reticle. The result? Faster acquisition, improved focus, and reduced parallax error—all with the same rugged reliability you expect from premium iron sights.
