Precise, durable, intuitive
C2 & C4 Sights
Ultradyne Iron Sights are CNC-machined for repeatable accuracy and built to withstand the field. With dual aperture technology and a low-profile footprint, the C2 and C4 deliver fast, consistent sight picture without bulking up your build. Made in the USA and engineered for shooters who demand performance.
the science of
dual aperature
Traditional iron sights force your eye to center a vertical front blade inside a rear aperture — a square-in-circle task that slows acquisition and can introduce alignment errors. Dual-aperture sights use two concentric apertures instead. The eye instinctively centers a circle within a circle, which makes natural, rapid alignment far easier and more repeatable.
How it works: look through the rear aperture, center the front aperture inside of the rear, pick up your target through the front aperture, and pull the trigger. The concentric geometry guides alignment for you, reducing parallax error. The result is faster target acquisition, improved first-shot accuracy, and more consistent follow-up shots under real conditions.
meet the
dynamount system
When force is applied to a handguard it can move out of perfect alignment with the barrel, and any sight mounted to that handguard will inherit that error. Dynamount solves this problem by mechanically fixing the front sight to the barrel axis — not the handguard — using an integrated interface with our muzzle brakes. That direct attachment eliminates handguard-induced error, preserves point-of-impact, and prevents MOA shifts that undermine precision.
BULLET DROP COEFFICIENT INTEGRATED IN
REAR SIGHT
Ultradyne C4 rear sights feature an integrated Bullet Drop Compensation (BDC) dial that puts precise, distance-based elevation adjustments at your fingertips. The indexed dial offers crisp, repeatable clicks, with each elevation setting calibrated to 50-yard increments from 200 to 600 yards, so you can quickly dial the correct hold for common long-range engagements. Once sighted in you simply dial to the desired distance, and can aim directly at your target.
Available in purpose-built calibrations for 5.56×45 and 7.62×51, each C4 BDC dial is tuned to the specific ballistics of its caliber to deliver intuitive, point-and-shoot adjustments. Benefits include rapid target acquisition at variable ranges, consistent click-to-impact accuracy, and an easy, shooter-friendly interface that keeps you on target without complicated math or guesswork.
