Using a Mirage Cap can aid reading mirage over long distances just by reducing the objective diameter of a scope. The result allows less light in and increases the depth of field, making the lines on a target appear more defined — especially on hot afternoons with heavy mirage. With three available sizes, there’s a cap to fit your TORIC 4-20X50, 3-15X50, 4-25×50, or 4.5-30×56 scope.
