Product Overview

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.


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.


  • 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
  • INTERCHANGEABLE APERTURE: Spare aperture conveniently threads into windage knob until needed
Made In United States of America
