The Huskemaw scope works on the basis of the carftridge and load you are using for it but one must remember the variances altitude and barometric pressure bring to the equation table.
The Huskemaw custom drop turret cap is included in the price but it is entirely optional as to whether you wish to use it
. The scope comes packaged with a standard cap with 1/3 MOA clicks. Then you send them your drop data to have them make your own custom drop cap.
If you don't like that concept then just use the original cap. But it is VERY easy to adjust for most atmospheric conditon changes anyway.
I use the Kenton Industries cap for my Nightforce scopes and like then very much.
