Kg doesn't know how red dots work - Vortex Crossfire II 1x25mm 2 MOA Reflex Red Dot Sights

The reviewer KG doesn't seem to understand how red dots work. Red dots have an LED emitter inside the sight housing that shines a beam of light backward onto the glass. The angled front lens acts like a curved mirror to bounce that red dot straight into your eye...A curved front lens on red dots is normal. This is a fantastic dotam and fantastic for the price. Don't let someone's lack of understanding of how red dots work keep you from buying this as the curved front lens is not a defect.
