Things to Consider Before Buying a Reflex Sight

While I do intend to review some of the best reflex sights For AR on the market, it is important that I share with you the factors that led me to settle on the sights below. Below are the main factors I relied upon when choosing sights to place on this list.

Note: If you have a Glock pistol and want to buy the best sights for Glock 43, then read the linked post.


The first thing I look for whenever I am buying any kind of tool is the material it is made from. Therefore, the first thing I considered was how durable the different sights were. Irrespective of cost, a reflex sight should be durable and tough enough to withstand harsh weather, like what we said in our single-pin bow sight reviews. In particular, I advise against buying a sight that is neither shockproof nor waterproof. The last thing you want is to buy a sight that will crack or get damaged after a few days of use.

Battery Life

Reflex sights use batteries. Thus, it is important to consider the battery life of a reflex sight. Sights that use LEDs consume less energy and can go for up to 1000 hours. When choosing the sights for my list, each one’s battery life.


When it comes to housing, reflex sights can be divided into two: open style and tube style. The category you settle on depends on your preference. Tube-style sights are similar to optical scopes and allow for easy installation of protective covers. On the other hand, the open style has an open window design without any covers. In this article, I have reviewed both types.


Accuracy is one of the most important factors to consider when buying a reflex sight. Since these sights are designed for rapid fire, shooting accuracy is key. I relied on user reviews and my own personal experiences in evaluating accuracy.

No products found.

When you have options such as the Sightmark M-Spec, are pricier reflex sights such as the Trijicon RMR worth buying? This is the question I sought to answer when I tested one of my hunting buddies, Trijicon RMR 6.5 sight.

While its unique design gives it a rather premium look, it is the sight’s targeting mechanism I was more interested in. I tested this scope in different light conditions, and it performed exceptionally well.

Largely thanks to its auto brightness adjustment feature. In regards to construction and weight, I found it to be very lightweight and very well made. The multi-coated lens looked brighter than that of my sightmark.

Unlike other sights in its price tag, this Vortex creation boasts of an aluminum construction.

The lenses on this sight are exceptionally clear and offer plenty of brightness. In this regard, the scope works well in all light conditions.

One of the lightest reflex sights I have ever used is the Vortex Razor Red Dot sight. Weighing only 1.4 ounces, this sight will add nothing to the overall weight of your gun. Apart from being one of the lightest sights on the market, it is also of exceptional quality.

But what I really liked about it is its emphasis on protection. It takes more than normal abuse to get this sight damaged.

No list of the best reflex sight would be complete without the EOTech 512.A65 Tactical Holographic sight. After all, this is the sight you will find attached to most people’s weapons, and for good reasons.

I recently got to test this popular Holographic sight, and I have to say, I can understand why it is the go-to sight for many. My first impressions of it are that it is very easy to mount and looks very well made. I was also impressed with its field of view.

Looking through the sight made me realize that its field of view was wider than most sights I have used. And unlike other sights, this one is powered by two AA batteries that give you 1000 hours of use.


  • 65 MOA circle: This circle has a target acquisition that is faster than that of most red dot sights I have used
  • Parallax-free magnification: This allows for aiming at targets with both eyes open, which is really useful when hunting
  • Two AA batteries: Powered by two AA batteries, this sight can provide you with up to 1000 hours of use. Also, these batteries do not corrode over like their alkaline counterparts

  • It is super bright for after-dusk use
  • It is easy to mount

Sightmark is known for producing affordable optics, and the Ultra Shot Pro Spec Sight is no exception. It is for this reason that I decided to buy myself the Ultra Shot Pro Spec. Its affordability aside, this reflex sight is a very good sight.

To start with, it comes with multiple brightness settings, which I find to be very useful. In addition to this, it took me only a short time to mount it on my rifle. And neither did I have any trouble zeroing the sight. Basically, this sight proved to be the best cheap reflex sight. Its price and features earn it a place on my list.
