The Ultradyne C4 sights offer an innovative approach to iron sights, allowing for target focus through the rear aperture and front post. They feature tool-less adjustment for the front sight and full windage/elevation adjustability on the rear. The reviewer found them surprisingly user-friendly and effective, even at extended ranges with subsonic ammunition, though a minor critique was the lack of a retention screw for interchangeable apertures.

Quick Summary

The Ultradyne C4 sights offer a unique target focus design, allowing shooters to see through the rear aperture, front post, and target simultaneously. They feature tool-less front sight adjustments and proved effective at 250 yards on a 300 Blackout PDW, though a retention screw for apertures is suggested for improvement.

Frequently Asked Questions

What is the primary advantage of the Ultradyne C4 sights?

The Ultradyne C4 sights are designed to facilitate target focus by allowing the shooter's eye to look through the rear aperture, the front sight post, and directly at the target, rather than aligning the post within a ring.

How are the Ultradyne C4 sights adjusted?

The front sight post features tool-less elevation and windage adjustments. To adjust elevation, you push down on the dial to disengage the lock, rotate to the desired setting, and release to re-engage.

Can the Ultradyne C4 sights be used at extended ranges?

Yes, the reviewer successfully engaged a 250-yard target with a 300 Blackout PDW using these sights and subsonic ammunition, demonstrating their capability beyond typical close-quarters use.

What is a potential area for improvement on the Ultradyne C4 sights?

The reviewer suggests adding a retention set screw to the rear sight's interchangeable apertures to prevent them from backing out during use, a minor issue encountered during testing.
