Great 3x prism sight if you have an astigmatism. - Swampfox Trihawk 3x30mm Prism Scope

Since there is a rather inconveniently placed delete button on the side of the comment box and this is the 3rd time I am writing this review I'm give the condensed commentary. Great eye box, reticle etching, and contsruction. Uses a CR123a battery. Prism optics are great for people affected by astigmatism because the reticle is etched and not projected, so its not blurry. The down side is the short eye relief. So if you wear glasses and have long arms you may not want to mount this on a AR15 because it will feel really akward with how close you have to get to it to eliminate scope shadow.
