Focus Levers and Rings
A thermal scope focus lever gives you something to grab when your fingers are cold and the image needs a quick touch-up. These levers and ring extensions give you more grip on the stock focus ring so you can adjust with a finger instead of a pinch. They are low profile so they won't snag, and installation takes only seconds.

Frequently Asked Questions
What is the difference between zoom and focus on a thermal scope?
Zoom changes how big the target looks, while focus makes the image sharp at a given distance. On a thermal, zoom is usually digital and the focus ring moves the objective lens. A focus lever lets you bring a coyote at 150 yards into sharp view without taking your eye off it.
What is the difference between a focus lever and a focus ring extension?
A lever sticks out from the focus ring like a small handle, so you can push it with one finger. A ring extension wraps around the ring and adds grip and diameter. Levers are quicker to find in the dark; extensions sit flatter. We carry both for many AGM, Pulsar and Bering Optics models.
Is Dark Night Outdoors a legit company?
We are a real shop in Milan, Illinois, with around 1,000 customer reviews and people who answer the phone and know the gear. Our own DNO branded parts, like the focus ring and cap for the Bering Phenom, carry a lifetime warranty against defects in normal use. You can reach us at (309) 781-8421.
Are aftermarket focus levers a legit upgrade?
For most thermal hunters they are worth it. Stock focus rings are small and stiff, which is hard to work with gloves on. A model-specific lever clamps on without changing the scope and comes off the same way. Just buy the one made for your exact model and lens size.
