Measure the outside of the objective front bell including scope cover if used and find size indicated in the chart below.
Measuring scope ring height.
Shep s easy and accurate method for determining the correct scope ring height for your rifle.
Make sure to follow the manufacturer s.
The first step is to install your scope mount on your rifle.
Another way to do it is to measure the scope tube diameter at the objective lens and half that.
Actual objective diameter 2 9 action diameter 2 base height required ring height.
Sloped bases add 035 to height every six inches objective extends from base for standard evolution chassis.
Measuring scope height approximately.
The formula will vary slightly depending on the type of chassis you are measuring for.
All units in inches.
Ring height measured from top of base to scope center line.
Mount height ring height bell diameter 2 cover wrap 6 50 mm 0 26 inches pass.
Using washers shims coins etc create two equal stacks on top of the scope.
That figure is your scope ring height.
If your scope has a 30mm scope tube add 15mm to the combined height of the scope ring and base to determine if it s greater than your scope height measurement.
Measurements are in inches from top of base to bottom of scope tube burris makes double dovetail in signature rings only burris extension is 625 5 8 leupold extension is 625 5 8.
So you need a scope with the same dimension 30 mm which have 1 18 inches height.
Other factors to consider.
The scope we are talking about has a 30 mm tube.
So our example and the equation demand we need 855 inches of ring height.
These methods of measuring scope ring height do not take other factors into consideration such as bolt action clearance or the presence of open sights and other accessories.
To arrive roughly at the scope height measure the diameter in mm of the objective lens the leading lens add 2 4mm for the thickness of the scope body and half the result.
If you have a 1 inch tube the height from the top of the receiver to the bottom of the scope tube will need to be.
Subtract approximately 100 inch from the 30mm minimum height requirement if using a 35 mm diameter ring and scope tube.
The scope base is not sloped and has 350 inch height from the bottom of the plate to the plane in between the risers on the picatinny rail.
Ring height is from the top of the base to the bottom of the scope tube.
