Ultradyne C4 Offset Folding Front and Rear Sight RH Combo

The C4 Offset Front/Rear Sight Combo is a dual aperture sighting system that is changing the way shooters think about iron sights. The C4 Offset Rear Sight offers Rock-solid performance in a compact form with a ballistically calibrated elevation system that adjust in 50-yard increments from 200 to 600 yards. The C4 Offset Front Sight brings precision front aperture technology to back up iron sights along with the ability to adjust both windage and elevation. Using these sights together creates a perfectly concentric sight picture that allows the shooter to see the target, enables faster sight acquisition and gives the ability to consistently shoot accurately at targets close and far. C4 Offset Sights are your best option for back up iron sights.

 

The C4 Offset Sight Combo uses Dynalign Technology to deliver a superior sighting system. The innovative four concentric circles create a sight picture that optimizes accuracy.

C4 Offset 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 Offset 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
• Elevation cam for most ballistic bullet paths available
• 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.
