Mueller offers scopes for nearly any use you can think of. Whether it’s for archery, crossbows, hunting, tactical or competition shooting, they have a scope that fits. Mueller is a rather new competitor on the hunting optics market and was founded in 2003.
Their optics are of good quality at a rather low price point. You won’t find the highest quality optics in Mueller scopes but for the price you will typically get a more than satisfactory scope.
