Think twice - Trijicon RMR HD 1x Reflex Red Dot Sights

I bought both the RCR and RMR HD when they were released. The RCR arrived in early December, zeroed easily and has performed well. The RMR HD arrived in early February. I mounted it to a Gen 5 Glock 19 and shot it today. I went through the entire elevation range and could not get it zeroed. I will check the mount tomorrow and try to zero again this week. If the RMR HD performs well I’ll update this post but until then think twice before buying this product.
