C4 Front & Rear Sight Combo
$299.00
Description
Made in the USAThe C4 Sight Combo uses Dynalign Technology to deliver a superior sighting system. The innovative four concentric circles create a sight picture that optimizes accuracy.
C4 Front Sight Features:
- Outer and inner concentric circles for easy target acquisition
- Windage adjustable for zeroing on the front sight, which guarantees that the rear sight windage is perfectly centered when at zero for maximum in windage adjustment in either direction along with easy return to zero
- Tool-less elevation adjustment that is always perfectly concentric with outer circle
- Aperture sight gives a shooter the ability to focus 100% on the target
- Strategic use of materials to maximize strength and weight
C4 Rear Sight Features:
- A purely concentric sight picture with an inner aperture and outer circle for easy alignment
- Rapid windage and elevation adjustments
- Elevation adjustment to 600 yards
- One-handed deployment and stowage
- Interchangeable Apertures, .70″, .50″ and a ghost ring
- Spare aperture conveniently stores into windage knob
- Strategic use of materials to maximize strength and weight
DYNALIGN TECHNOLOGY: Concentric Sight Picture
Most BUIS systems utilize a sight picture that is non-intuitive.
The brain’s visual systems are asked to align a circular rear aperture with a rectangular front post shape while simultaneously ignoring the “ears” that protect the front sight post.
Dynalign’s circle-within-circle sight picture allows for faster sight picture acquisition.
Additionally, the use of a front aperture further reduces parallax effect which makes accuracy less dependent on precise sight alignment.
Dynalign is a faster and more accurate sight picture that can improve shooting performance.

I really can’t believe I’m the 1st review on here!!! Especially given how great these sights are! I’ll tell ya’s these are quite literally the BEST iron sights I’ve ever looked through, bar none as far as type of weapon, I freakin LOVE EM…I could guarantee how great these are but ya’ll don’t know me, but I absolutely can swear by em!!!!

Best BUIS on the market. I run these sights on 3 different builds. The look through design allows for dead on precision. Hands down the only iron sights worth buying

I’ve got these on 2 different CMMG carbines. They are extremely well made, very easy to adjust with no tools needed, and lay flat and beautiful on the rail. Made is USA. Pricey but love em.

I’ll repeat what the other reviewers have said. Best, quick sight pickup. I run the smallest aperture, get everything adjusted and then set up a red dot purely off of the UD C4. In low light the red dot is a nice aid. Best AR sight I’ve tried and I passed some expensive versions of other “name” sights on to other folks.

The C4 sights are the fastest iron sight picture for me to acquire, period. I use them on all my SBRs. I use them on my rifles that reach out and touch as well. The concentric principle that is in the design brings my speed and precision to a new level with irons. The materials and machining is excellent, extremely durable and smooth consistent function. The overall design for sighting in and for shooting out to distance has been well thought out and has no equal for irons. I also appreciate the ability to store the distance aperture to the side. The company has been very prompt and professional to work with and a pleasure to talk to. These are my rifle irons on all my builds whether trainer or duty. I will continue to buy.
