Questions & Answers
Are these spring-loaded flip-up sights? Manufacturer Answer

The C4 Sight System's fold-up mechanism is not a spring-assisted flip-up. The C4s utilize a positive detent so the sights deploy/stow one-handed by manually flipping them into position, and while shooting, they stay deployed due to the detent.

by Ultradyne USA, Manufacturer, October 8, 2025
Are these for 5.56? Expert Answer

The Ultradyne C4 Flip-Up Front/Rear Sight Set can be used with an AR15 chambered in 5.56.

Folding sights by Tophat, Verified Owner, September 11, 2022
This is the best sights that I've ever tried adjustments are easy to dial in. These are not those cheap composite plastic made sites. These sights prevent parallax issues that you have on the cheaper sights that are available.

Nice Irons by David Cacace, Verified Owner, August 26, 2019
I like these irons, they are easy to use and adjust. You need to know these Zero at 200 yards to start with and go out from there. They do take a little bit of getting used to as your looking through the front sight at your target.

Expensive, but really nice! by gospyro, Verified Owner, November 15, 2022
These are quite pricey, but the simple hole in post of the front sight really makes a difference so these an excelent set of iron sights! The over all quality is top notch, with a clean, solid snap when flipping them up.

Ultradyne C4 308 review by Greg, Verified Owner, March 29, 2023
I read the reviews and they all had nothing but good feedback so I bought these for my M&P 10. I used these for the first time and overall they are a great product. The one complaint I have is that the rear sight would partially fold down sometimes...
