Moondog Industries got the CVLife 4-Reticle Reflex Sight to find out if it is the best budget reflex sight in the market... "How well does a $30 4-Reticle Reflex Sight perform? Will it hold zero? CVLife makes some of the best budget shooting accessories and optics and they sent me this model to review. Like other Sureshot clones, this suffers from the benefits and shortcomings of the open Reflex design: Maximum visibility but minimum protection from the environment."
