It may be necessary to run taller scope rings to clear the hand guard. Use the following formula's to determine your necessary ring height.
(All units in inches. Ring height measured from top of base to scope center line. Sloped bases add .035" to height every six inches objective extends from base.)
For standard Evolution chassis:
(actual objective diameter/2) + .9 - (action diameter/2) - base height = required ring height
For Evolution HD chassis:
(actual objective diameter/2) + 1.05 - (action diameter/2) - base height = required ring height
These formulas are provided as an estimate and do not guarantee correct fit. Use your own discretion.
The scope base on your rifle can extend .200" past the action face. If your base is longer, we can shorten it for you at no charge.
