Description

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
