What’s the Best Reflex Sight Under $100?

Are you in the market for a new reflex site? As the name suggests, the projected aiming point is reflected back so you can see the red dot. The number of models on the market can seem unlimited. We’ve sifted through dozens of models and concluded that the best reflex site under 100 is the Red/Green Dot Reflex Sight by Ohuhu.

It’s the only one you’ll need for hunting or target shooting. The under-$100 unit is super-light, shockproof, and waterproof. It has a tubeless scope design with 33mm reflex lens. The multi-reticle reflex includes 4 patterns and 4 sized dots. This offers a wide field of view (FOV) for shooting at moving targets or rapid-firing.

The Red/Green Dot Reflex is also equipped with unlimited eye-relief and is parallax corrected. Elevation and Windage adjustments are made with locking screw. The built-in mount is designed for standard 20mm bases, so no re-zeroing is needed for rifle/pistol remounting.  This unit is even bundled with the 3V lithium battery so you can use the reflector scope right out of the box.

Product Review


This reflex-type sight is quite lightweight at 1.6 ounces and compact with dimensions of 4.7 x 3.7 x 1.4 inches. This makes it easier to operate during day-long hunting sessions.

Small weight differences of components like sights might not seem like a big deal. It’s a different story when you’re in the field all day lugging around your rifle. In that case heavier rifle accessories can feel like a ton by late afternoon.


The Red/Green reflex-type sight is powered by a 3V lithium battery. This type of battery is efficient and long-lasting so it’s quite common for rifle scopes. Since it’s bundled with the sight you won’t have to spend extra money on the battery pack.

FOV/Lens Aperture

Ohuhu’s reflex-style sight offers a 33m lens aperture that provides an ultra-wide field of view (FOV). This is critical in the field for providing you a clearer view of the landscape and your target.

It also provides more versatility. You can use the sight for various applications like shooting at moving targets and rapid-firing. This eliminates the need to purchase different sights for different applications.


This unit also offers pre-installed multiple patterns and dot sizes, so there’s no need to make tweaks before using the unit. It’s another way you get more versatility since you can make more precise shots in various situations. It’s also a plus versus other similar sights on the market offering fewer reticles and/or dot sizes.

Eye Relief

The unlimited eye relief is a key feature. This helps to provide a wider field of view and offer more viewing comfort. Unlimited eye relief is somewhat common but is certainly an important feature for offering more value to the unit.

Parallax Corrected

This is a critical feature since parallax produces an optical illusion that must be fixed. This is different from focus and the parallax is also unrelated to focus. Parallax correction moves the planes of the reticle/image focus. The feature can definitely help to provide accurate shooting.

Windage/Elevation Adjustments

These are tweaked by screw-type click adjustments. The process is quite easy, so you won’t have to spend lots of time and effort making tweaks for wind and elevation.


The mount is built-in and can be used for standard 20mm bases. This helps to prevent the need to rezero when you remount/dismount the Ohuhu sight. The unit has received high marks for the mount’s quality and durability.

When mounting the sight, it’s important to provide 3+ inches of clearance between your eye and end of LED/Mirror Housing. The built-in rail mounts quite securely to the bases. In fact, several customers have shared that it mounts as securely as several high-end reflex sights on the market.


This sight is both waterproof so you can use it in rainy/snowy weather. It’s definitely a plus over other sights that are only water-resistant since they won’t be protected from heavy precipitation while you’re in the field.

It’s also shockproof, which provides more durability and extends the lifespan of the unit even if it gets bumped around in the field. This, in turn, will help to extend the lifespan and prevent the need to replace it sooner rather than later.


This Ohuhu reflex sight not only is in the under-$100 range but is available at various online retailers for under-$50. While the price tag is rock-bottom, it offers outstanding value for the price.
