Huskemaw scopes offer one advantage over their competitors. They have a patent on ballistic turrets that have a second row of numbers for windage holdovers. Without a license to their patent, other scope companies cannot offer this feature. Burris C4 scope turrets initially had a second row of windage holdovers. Burris had to change their C4 scope turret designs to omit this feature. They now provide a separate label with windage holdovers that users attach to the scope objective bell.
The Huskemaw patent probably does not apply to ballistic turret labels sold by Custom Turret Systems. The sale of a label does not appear to infringe on the Huskemaw patent, which covers scopes with turrets, but not labels for turrets.
