Ultradyne C4 Flip-Up Rear Sight LR-308 Aluminum Black

The Ultradyne C4 Flip-Up Rear Sight is a high quality folding rear sight that was engineered with accuracy in mind.  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.
