Rectangle beats the circle - Diamondhead Polymer Diamond Integrated Sigting System With Nitbrite Top Mounted Deployable Iron Sight

Using iron sights to hit your target should be easy and the circle just does not do it. The ability to have corners to line up especially if you are shooting with less than perfect visual acuity is enhanced with the Diamondhead Rear Sight. The light polymer sight that can be flipped down is a real benefit to accurate shooting.
