Optics / Scope Mounts

  • The majority of our rifles are built using Leupold scopes using the CDS turret system.  We prefer to use Leupold VX-R, Leupold VX5 and VX6 scopes.  We have built many rifles with these scopes and great results.  If you choose to go the route of the Leupold CDS system we will match the drop of the ammunition to the CDS turret cap.  We will build the rifle with a customer supplied scope as well.
