This mounting kit allows you to place a DeltaPoint Pro Red Dot Sight on top of Leupold Mark 4 rings and IMS mounts. The mounting plate features multiple holes so you can place the sight farther forward or back on top of the ring. It can be installed on either side at a 45Adeg angle or directly on top. The addition of a red dot sight aids in rapid close-quarter target engagement along with target alignment at longer distances.Notes: Not compatible with Mark 2 IMS mountsMounting hardware included
