Congratulations on your new Nikko Stirling Diamond Long Range scope!

The Diamond LR scope offers accurate ballistic drop compensation turrets including RTZ® (Return to Zero).

The RTZ® (Return to Zero) elevation turret allows you to find your closest zeroed in shooting distance just by this stop.

The elevation and windage is based on ¼ inch at 100yds click increments.

Please note:
This equals very accurate to ¼ MOA or 7mm at 100m.

The scope is supplied with 2 Ballistic Drop Turrets:

How to use the Diamond LR scope in the field?

Nikko Stirling recommends to test several distances on a proper shooting range to verify the correct point of impact before hunting.

Use a laser range finder to measure the distance to the target. A precise measurement is important to ensure the proper shooting results.

Using the Ballistic Drop Compensation Turrets:

Pull elevation turret and adjust to required drop marking.

Now you are dead on.

Use the center cross of the reticle and fire. If you want to lock the setting push down the elevation turret.

Good sports!
