The C4 Front Sight is the first of its kind, bringing precision front aperture technology to backup iron sights. Interchangeable front sight apertures provide options for any application.

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.

In addition to its revolutionary sight picture, the C4 Front Sight provides additional features: 

TOOL-LESS ELEVATION ADJUSTMENT
Make hassle-free adjustments anywhere, anytime.

WINDAGE-ADJUSTABLE FOR ZEROING
Regain full range of rear windage adjustment and guarantee center-zero operation.

MULTIPLE FRONT SIGHT PIN OPTIONS
Choose from traditional post or multiple Dynalign front apertures.

100% CNC MACHINED IN THE USA
American-made quality.
