Please note: All clearance calculations are based on mounts with 0 MOA. While MOA can be factored in, actual clearance may vary due to variables that can't always be accurately calculated. If you're considering an MOA mount and are unsure about the required height, we recommend contacting our sales team directly.
Measure the outermost diameter of your scope’s objective bell (including any flare).
Measure the thickness of any scope cover if used. If none, leave as 0.
Measure from the top of the rail to the highest point of the barrel.
We add a little extra clearance to account for real-world variation. Default is +1 mm.
Enter your measurements above to calculate the lowest ring height (base-to-centre) you can realistically use.
(A + 2×B) / 2 − C + TWhere A = objective outer diameter, B = cover thickness, C = rail-to-barrel clearance, T = tolerance.
