You need a flawless targeting system to ensure the highest accuracy and consistency while shooting. For a low light shooting, it’s really tough to have such accuracy and consistency. It can greatly help here. Things get better when it comes to the Vortex Optics. If you have previous experience of using Vortex spotting scope, you know what I am talking about.

So far, vortex optics is leading this industry and this model is highly appreciated and recommended for tactical shooting. It’s just perfect for your shotgun, pistol, and rifle. Mount it on your Glock 17 MOS, Canik TP9 SFX 9mm or  Glock 40 GEN4 MOS and it will be just sublime. 

Unparalleled clear optic, so your target can never be blurry. Even if you keep your eyes open, the target acquisition will be perfect. You no longer have to squint to obtain the precise focus. And for the dark location, nothing could get better than this. 

Tips: if you see the dot to be fuzzy, definitely it’s the problem of your eyes. I saw some complaints calling the fuzzy dot. You may have astigmatism and a contact lense will help you greatly.

Once it is zeroed, you don’t have to adjust it for a very long time. Heck! People have shot more than 1000 rounds and the Zero is holding just right. The outstanding battery (CR1632 3V) will amaze you greatly. Helps you great in a long competition like the USPSA. Just turn it on and you don’t have to turn it off until the competition is over. 

You do not have to adjust the brightness repeatedly. The auto-brightness feature works like a charm. It does not matter whether it is a bright daytime or there is low light. You will never face problems seeing the dot. It’s really a better version than the Vortex’s Viper model.

Installation is pretty simple and straightforward. Boresight process is fairly simple and you will be amazed seeing how perfectly it holds the boresight.

After the 1000 rounds of shot, the strikefire still can maintain the zero. So hands down to this really badass RDS from the trusted Vortex. Don’t take my word for it, this is just how satisfied users have reviewed it. At this price, this is simply unbeatable.

Experienced shooters have confirmed that you will be wasting your money if you go for other brands or even other models! And do you know who are these shooters? They are people with 18+ years of military service! Trust me, you don’t need any more validation.

You can dim it or brighten it as per your requirement.  A huge plus! It has impressed people thoroughly with its outstanding precision and performance of quick and precise target acquisition. So many shooters have used it in all kinds of weather and it never lost the zero. More so, had no trouble as well. Did not have to replace the battery even after 1.5 years!

Just like the previous one, water is not an issue. People have used it under heavy rains without any issue. Highly recommended for people with a limited budget but want durability, quality, and accuracy. The overall appearance is good and it fits firmly to the rail. It exceeded expectations from so many people that they have bought it again.

People who have bought this for the first time, waited a few months to leave accurate reviews. They call it the most crystal clean RDS. People tried it on different guns like the shotgun, rifles, Glock, and so on. You will even get the awesome result using it with your Colt AR-15. 

Even on the brightest days, you will be able the see the target crystal clear. Dark environments?  No problem! With the cantilever mount, you will be able the see the iron sights. Pretty well-built with super clear glass.

You want to pick the dot flawless, even if your groups are tight? Burris Fastfire III is for you. It has everything you need and it is within your budget – a sweet deal that you should consider seriously. More than thousands of hundreds of happy shooters have recommended it for their buddies.

For such quality, you would have to spend twice or thrice the price; but Burris made it inexpensive and so competitive. A perfect alternative to all those highly expensive options. And don’t forget you will get the same nice sight with a lot of range adjustment options.

This model itself has 5 modes of operation like the automatic, high, low, medium, and off. The automatic features work like a charm. It will automatically adjust to the current lighting condition. If you are suffering from astigmatism, you should go for the low setting.

Lots of shooters have tried it with their M&P9L C.O.R.E. pistol, Smith & Wesson M&P 9mm and they are impressed with its performance. This works great with the Glock MOS system as well.

They took it to the range and faced no trouble zeroing the sight at 10 meters and more. With the impressive sight, even the older people were happy as they achieved an accurate target with it. The only thing that could be better than this is having a holographic weapon sight.

Some people bought it mostly because of economic reasons and seeing a lot of positive reviews out there. They did not regret it; in fact, they are really happy with their purchase. Just because it is relatively inexpensive than their counterparts; don’t think it is an inferior product. People with a lot of years of shooting experience have recommended it.

Here is the unboxing and video review of it.

And this RDS is not perfect for just the shotgun or rifles, it is perfect for the Glock 17 MOS, Glock 35 MOS, Glock 34 MOS or any other weapons that have a rail to mount it on. After several months of usage and shooting more than 1,000 rounds, people have been impressed with its performance.

Buying Guide For Your Best Red Dot Sight For Shotgun


RDS is not something you buy every day. But it is as important as having the shooting earmuff in the range.  They are costly but a must shooting gear. So you need to be careful while picking yours. There are a lot of counterfeit products out there. Some of them are genuine but may not be suitable for you. So, here is the ultimate guideline for you to pick the right one for your firearm:

Pick The Right Size

This is the most important factor you need to take into your account if you want to avoid disappointment. All the quality RDS offer the same task but not all of them are of the same size. If you have a shotgun or a rifle, you will need a bigger RDS, but if you have a small firearm like a pistol, you will need a smaller one.

The Price

Of course, there is a direct relationship between the cost and the quality of the RDS. While this is true, I reviewed some inexpensive model above that offers impressive performance. If you are on a tight budget and just learning how to shoot precisely,  you can go for them. Brands like the Leupold and Trijicon offer highly expensive RDS which is a better solution for the skilled shooters who can’t compromise the quality. 

Check The Battery

Look at the lifespan of the battery and how easily it is accessible. Always get the readily available battery. Do not go for the special order battery. Any special order battery will put you at a great disadvantage in the coming future. 

If you are just in the training phase, consider the RDS that has the longest battery life expectancy. The manufacturer of the sights will clearly mention the life expectancy of the battery. Make sure to read it. Also, make sure the replacement of the battery is easily available.

Open or Tube Option

You need to seriously think about whether you will go for the tube option or the open option. You may know the open option as the window design as well which offers a better scope of vision than the tube style. But they get damaged very easily.

On the other hand, the tube style is well protected but offer a limited scope of vision. Which one should you prioritize depends mostly on your requirement.

Reticle Size

You may not be aware of it but the size of the RDS itself plays a huge role. If you are more concerned about taking the most precise shot at the longest distance, consider having the smaller reticle size. This is suitable only for skilled shooters.

But if you are a new shooter, you should go for the bigger reticle sizes. It is not ideal for long-distance shooting but it offers a wider viewing area which is just perfect for the newbie.

Safety Alert!
Whether you shot a shotgun or a Glock, an RDS will definitely help you to achieve the target easily. However, what’s your opinion about shooting safety? Ensure all the shooting safety protocols like wearing shooting ear protection, eye protection, and so on.

When you have to have the best red dot sight, you have to trust the reputed brands only. That’s why I have reviewed only a few of the above. You can either go for the Vortex or the Leupold, the choice is yours and you will definitely not regret having the RDS from them.
