- To use this to it's full potential the use of a `Vector 21` is strongly recommended, a `Kestrel 4500` will also help.
- Pull out your rangefinder (`Vector 21` preferred) and get the distance between you and your target.
- Open your rangetable and look under the `Target range` column.
- Move to the `Bullet Drop` column, the drop is in MRADs, you need to compensate for it by adjusting your sight. Example, you want to adjust for a bullet drop of -7.9 MRADs simply adjust your scope 7.9 MRADs vertically. (check [feature scopes](http://ace3mod.com/wiki/feature/scopes.html) ) for this.
