C4 Dynamount Folding Front Sight + Athena Linear Comp

Description

Dynamount Information

Most of the time, shooters mount front sights on the picatinny rail of a free-float handguard.

By deffnition, a free-float handguard doesn’t move with the barrel. This means that when the handguard moves, the sights do too.

Even properly-installed handguards move, whether it’s from the weight of the firearm, a strong grip, or impact. Especially at the end, farthest from the point of attachment, and where most users mount sights.

A small amount of movement can make a big difference in point of aim. Movement as little as 0.01 inches at the handguard means almost 2 inches at 100 yards.

The solution is Dynamount. Barrel-mounted sights for consistent aim, every time.

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 DYNAMOUNT FRONT SIGHT is a high quality folding front sight that was engineered with accuracy in mind. Features include:

DYNALIGN SIGHT PICTURE TECHNOLOGY
Ultradyne exclusive alignment for accurate and immediate acquisition.
