C4 Rear Sight
The C4 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. An integral part of the C4 Sight System, best paired with the C4 Folding Front Sight.
The Dynalign sight picture provides more accurate and faster target acquisition, using a purely concentric sight picture that is similar to that used by Olympic target shooters. Unlike red-dot or holographic sights, this sight picture does not obscure the target and actually enhances visibility due to the optical characteristics of apertures.
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.
The C4 REAR SIGHT is a high quality folding rear sight that was engineered with accuracy in mind. Features include:
DYNALIGN SIGHT PICTURE TECHNOLOGY
Ultradyne exclusive alignment for accurate and immediate acquisition.
ONE-HANDED DEPLOYMENT AND STOWAGE
Postive detent allows operation without manipulation of buttons or latches.
SUPERIOR SIDE-ADJUST ERGONOMICS
Rapid windage and elevation adjustment from 200 to 600 yards at your fingertips.
Spare aperture conveniently threads into windage knob until needed.
