This sight is an aperture sight. Thanks to the optical characteristics of apertures, it’s easy to tell if the front and rear apertures are aligned with the target. If you can see the target clearly without blurring, the sights are aligned with the target. Conversely, if your view of the target through the apertures is not crisp, the sights are not aligned with the target. Both front and rear sights are compatible with other manufactured sights. However, these instructions are intended for use with the Ultradyne® C4 Sight System which includes both a front and a rear sight and may not be applicable to other combinations.


Ultradyne makes some of the best high end iron sights around. Oakland Tactical is Southeastern Michigan's premier Ultradyne dealer, and we regularly circulate new product in and out of our inventory!
