Good 3x prism scope - Primary Arms SLx 3x Prism Scope w/ ACSS 5.56 Reticle

If you have an astigmatism then an etched reticle prism scope is for you. This sight makes it easy to hit targets from 25 yards out to 300 with ease! With some practice cqb ranges are also doable but not as fast as a 1x prism scope or red dot. However there are 2 cons for me - 1. The reticle is too busy for me. 2. Eye relief is short so you will have to remove the rear buis. This isn't a major problem though because it has an etched reticle so even if the battery fails you still have something to aim with. The scope would have to be practically destroyed before you're out of luck and if the scope is destroyed then chances are so are any rail mounted buis.
