Scope Ring Height Calculator

Enter your measurements below to calculate the minimum Scope Ring Height required.

Formulas are for Evolution, Evolution HD, and Carbon chassis only. Envy and Element chassis systems require separate equations due to wide variances in barrel contours and optics placement. Note: Ring height measured from top of base to scope center line. Sloped bases add .035" to height every six inches objective extends from base.
