Main highlights

•NOTICE: Astigmatism can cause a red dot reticle to look blurry/fuzzy/have a tail/duplicate dots/etc. This is a VERY common eye condition many have but are unaware of. A quick at home check is to take a picture of the reticle with your phone’s camera as your phone cannot have an astigmatism.
•NOTICE 2: Another issue can be from having the brightness setting up too high in a bad lighting environment like being indoors. Try turning the brightness down and repeating the previous suggestion if the reticle is still blurry to your eyes. If the reticle is still blurry in both pictures, there may be an issue with the reticle that is covered.
•Red-Illuminated patented ACSS Vulcan Dot Reticle System
•Two Reticle Settings: Dot + Circle, and Dot only
•RMR Footprint
