Best Optics for Night Hunting with an AR-10?

April 5, 2026

Quick Answer

For night hunting with an AR-10, I recommend a high-quality first focal plane (FFP) scope with a 3-12x magnification and an objective lens size of 42mm or larger, preferably with night vision capabilities such as image intensification or thermal imaging.

Choosing the Right Night Vision Scope

When it comes to night hunting with an AR-10, the right scope can make all the difference. I recommend a first focal plane (FFP) scope, which provides a more accurate ballistic calculation and a wider field of view. A 3-12x magnification range is ideal for most night hunting applications, as it provides enough magnification to identify targets at longer ranges without sacrificing low-light performance. A 42mm or larger objective lens size is also recommended, as it allows more light to enter the scope and provides a brighter image in low-light conditions.

Thermal Imaging for Enhanced Night Vision

Thermal imaging (TI) scopes are an excellent option for night hunting, as they can detect warm-blooded targets in complete darkness, even in areas with heavy vegetation or snow cover. TI scopes use a specialized sensor to detect heat signatures, which are then displayed on a screen or reticle within the scope. This allows hunters to identify targets quickly and accurately, even in the most challenging low-light conditions. When choosing a TI scope for your AR-10, look for one with a high-resolution sensor, a wide field of view, and a user-friendly interface.

Image Intensification for a Brighter Image

Image intensification (II) scopes are another popular option for night hunting, as they amplify available light to produce a brighter image. II scopes work by amplifying the available light, rather than generating their own, which makes them more energy-efficient and quieter than TI scopes. When choosing an II scope for your AR-10, look for one with a high-gain setting, a wide field of view, and a durable design that can withstand the rigors of night hunting.
