Ultradyne C4 Sight System – Dual Aperture Technology

Description

The Ultradyne C4 is a dual aperture sighting system that is designed to challenge the classic iron sights in the market with its impeccable performance of rear sight in a compact form with a ballistically calibrated elevation system that adjust in 50-yard increments from 200 to 600 yards.

The C4 front sight bring precision front aperture technology to backup 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 out to 600 yards and beyond. All of these in a compact and foldable sight system.

The C4 Sight System 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 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 durability and minimize 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 durability and minimize weight

Dynalign Technology

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 significantly improve shooting performance.

The Ultradyne C4 Sight System is a rear and front sight combo that is meticulously designed to deliver the most accurate shooting experience in a compact and lightweight package with tool-less sighting knobs for immediate adjustments.

The C4 Sighting System is set up for standard M193 ammunition or equivalent that’s a 55gr bullet travelling at 3200-3300 ft/sec, with this ammunition the set ranges on the C4 Sights will be the most accurate, if you are using a different ammunition, you’d need to verify the point of impact for that particular ammunition.
