KSG is one of my favorite weapons. I like the design, capabilities, and also accuracy. Although it has decent sights, which are not standard, they are still iron and I believe there are better options. That’s why I will help you by revealing the best sight for KSG. As a matter of fact, I will present you top 5 options. After extensive testing, I have determined that the Vortex Optics Strikefire II Red Dot Sight is the very best.
First a bit of overview. The KSG is developed by Kel-Tec and it is a 12 gauge pump-action shotgun, one of the best and most popular[1]https://www.keltecweapons.com/about/. It has 2 magazines and a user can switch between them manually. Each magazine holds 7 shotshells (70mm) or it can hold 6 (76mm) shotshells, depending on the need. There is also a larger version of KSG-25, but this is a different topic.
KSG comes with 26.1 inches of length and a weight of 6.9 pounds. The barrel is 18.5 inches long. The feed system is 7+7+1. This is a very powerful weapon that I have been owning for several years now.
Some of you will like to know that particular weapon has been used in South Korea, France, and also the United Kingdom by the SAS. Many private military companies have been using this weapon as well. Now, let’s start with the best KSG optics.

Review of best sights for KSG
Consider using any of these sights for your KSG.
- Vortex Optics Strikefire II Red Dot Sight
- HOLOSUN – HS510C Reflex Red Dot Sight
- Meprolight Self-Powered Reflex Sight
- Bushnell Trophy TRS-25 Red Dot Sight
- AT3 Magnified Red Dot
#1. Vortex Optics Strikefire II Red Dot Sight
First of all, these KSG sights come in two different colors of the dot, red and green. Then there are fully coated lenses that will make sure image quality is always at the highest level possible. Unlimited eye relief is also present. Windage and elevation adjustments can go up to 100 MOA.
This sight is filled with nitrogen. It is strong and suitable for all kinds of operations. In addition, it can be used with iron sights at the same time so users who want this option will like it as well.
The controls on the sight are located at the rear which makes adjustments easier and simpler. In addition, this model uses a CR2 battery to power itself. Replacing the battery is straightforward and relatively simple. However, the size of the optic makes it too big for handguns. In my opinion you could not consider this optic to be one of the best Browning Buckmark optics that I’ve tested.
Is it compatible with AR?
Yes, this sight is fully compatible with AR and installation can be done within minutes. In fact, I also rated the Strikefire as one of the best scopes for M&P 15 rifles. There are no complicated steps or anything else that can affect the installation in a negative way. In general, it is a versatile sight.
What is the MOA rating on this sight?
The MOA is 4 meaning the sight is ideal for various applications. Keep in mind that a higher MOA value makes the sight more suitable for close distance targets[2]https://vegetableipmupdates.arizona.edu/sites/default/files/200318_moa-classification_v9.4_3march20.pdf. A lower MOA is suitable for long-distance targets.
Can I install it on an AK rifle?
Yes, the sight can be installed on this weapon as well. There is no need in telling you that the installation is straightforward and there are no additional accessories you will need.
Do all versions have red and green dots?
There are 2 versions of the sight. Both of these come with red and green dots. These are called red dot sights, but they have 2 colors. Vortex optics have some problems, but they are very adjustable and durable sights.
Who is this for: I believe that users who need a heavy-duty sight for KSG to use while hunting or home defense will be perfectly happy.
Why I like it: I like the sight thanks to the rigged design, 2 colors of the dot, and clever adjustment options that are available.
#2. HOLOSUN – HS510C Reflex Red Dot Sight
- Best Value For Your Money
- Three Reticle Options
- Performs In All Weather Conditions
- Bigger Optic - Takes Up More Rail Space
I have known Holosun makes great optics since I tested the 507k and 407 red dots. The 510c is no different! Holosun HS510C uses advanced LED technology, has 50000 hours battery lifespan and also offers 2MOA which makes it ideal for long-distance targets. Users can choose between ring only, dot only, or use both reticles if needed.
The unlimited field of view is also present. The sight is made from aluminum and coated with titanium and completely resistant to chocks. An interesting advantage is that it is powered by a battery and can also use solar energy to power the dot. I discovered that this feature actually works and it isn’t mandatory but it is an appealing one to have.
This KSG sight has an integrated QD mount which makes installation and also removal extremely easy and makes the entire process last a few seconds. The dimensions of the sight are 4.75 x 3.62 x 3.12 inches and the weight is 8.3 ounces. The diameter of the objective is 30 mm. This quick detach feature of this optic actually reminded me of the EOTech EXPS and the XPS red dots, which are very easy to use.
There are 4 variations of this sight. These are 407, 507, 510, and 512. The differences include the size, weight, and also ideal weapons. For example, 407 is ideal for pistols, while 510 is recommended for rifles and carbine installations.
Where the sight is made?
The sight is made in China. However, it is well-made, comes with superb quality and there are no issues of any kind. That’s why I also rated this one of my favorite 300 blackout sights as well. There is an advanced production quality involved.
Can a battery recharge using only solar energy?
No, it isn’t possible to recharge the battery simply because it isn’t rechargeable. Solar power will be used when sight is exposed to the sunlight and preserve energy from a battery.
What is the latest version of the sight?
The latest version is 512 and it is recommended for rifles and carbine applications. It is large and comes with multiple adjustment options.
Can it be used for weapons with weaver rail?
Yes, this sight was designed specifically for weaver rail, and as such installation can be performed on any compatible weapon. This is why Holosun also makes some of the Best Red Dot Sights for AR15s with Fixed Front Sights.
Who this is for: Users who want the ability to choose between different options, use high-quality sight, and install it easily will be proud owners.
Why I like it: I like this sight simply because it comes in several versions, offers great accuracy and it also looks good.
#3. Meprolight Self-Powered Reflex Sight
The main advantage is the fact it was developed with the cooperation of Israeli Special Forces. Although you should know that this red dot set up is NOT just for military purposes. It is available in 4.6MOA and 5.5MOA. Supported reticles include triangle, bullseye, and X reticle. I tested all variations but ended up with a triangle version.
This is a self-powered model meaning it has no batteries. Installation is possible thanks to the use of simple systems. There are 2 quick release levers so removing the sight is simple as well. Of course, adjustments are available and powerful as well.
This sight isn’t for everyone. It is a simple, heavy-duty unit that can be used for ages for the most demanding and complicated operations. It looks like a military sight, which it is. The unit is ideal for KSG simply because it shares the same purpose.
Is this an anti-reflection device?
Yes, this is an anti-reflection device and it works perfectly in all situations.
Can the tritium be replaced and how long it lasts?
The tritium lasts for 12 years and it can be replaced after that. This isn’t the simplest process out there but it can be completed by most users without any use of help from a professional.
Is lens cover included?
No, there is no cover for the lens and therefore it isn’t included in the package. It is possible to find an optional cover, a generic one.
Can I see the reticle during the day?
Yes, the reticle is visible at all times. Due to the fact, there is no battery inside, the reticle cannot be turned off and it won’t be visible only in case of damage.
Who this is for: The sight is ideal for heavy-duty usages and users who want a powerful sight to use while hunting or other, advanced purposes. It is basically a military-grade sight.
Why I like it: I love the accuracy, the fact there are no batteries involved, and the overall strength of the construction. Now I can finally have a proper, military sight on my weapon.
#4. Bushnell Trophy TRS-25 Red Dot Sight
The unit comes with 16 mm lens diameter and offers 1 time magnification. It is fixed sight meaning that the magnification cannot be changed. After all, this KSG sight is suitable for close distance targets. KSG is a weapon for the same purpose so you can see why I chose this model to be on my list. I also tested this optic on rifles & found it to be one of the very best AK optics on the market.
The amber dot of 9MOA is used and it is very desirable to see. The main advantage is the dual illumination setting and the fact this unit is powered by a tritium power source. It can last around 12 years. It can be replaced after that and you can continue using the sight.
The sight here is made of aluminum, forged version so it is strong and will last for a long period of time. This also makes it lightweight, which is something I am very interested in. As a matter of fact, the weight of the sight is only 1.2 ounces.
Are different MOA ratings available?
Yes, you can choose the 7MOA version as well. However, there is no low MOA variation available at the moment. The sight is developed with high MOA only, for specific applications.
Can it be installed on Glock 43?
Yes, it can be installed on this weapon as well. The process is slightly different than with installation on rifles but still simple and straightforward.
Is this a heavy sight?
No. As a matter of fact, this is one of the lightest KSG sights I was able to find. It weighs only 1.2 ounces which is impressive.
What is the power source?
The power source of this sight is tritium. It can last up to 12 years and it can be replaced after that. There is no battery inside this sight.
Who this is for: People who need tritium powered sight to use on a daily basis with high MOA will like this model.
Why I like it: I was impressed with the lightweight advantage, the high MOA, and how fast the sight is when it comes to target acquisition.
#5. AT3 Magnified Red Dot
This product is different and comes as a kit. You get the sight and the laser sight with 3 times magnification. The MOA is 2 and there are 11 brightness settings available so a user can easily choose the desired one, according to the lighting conditions. Having several brightness settings is a key feature that I also found in many of the top turkey hunt shotguns that I tested. The lens is coated in multiple layers and it is immune to scratches and light damages.
It is versatile as well. There is 3 times magnification present allowing users to use the sight for different distances. The battery can last up to 50.000 hours (when the lowest brightness is used). The sight is waterproof and immune to fog and similar issues. It is made from strong metals and has a steel mount.
The package is complete. I mean that new owners get the sight with a laser, magnifier, the Allen wrench for installation, and the flip to side mount. The battery is included as well. The total length is 2.4 inches while the weight is 3.6 ounces. Eye relief is unlimited.
Can laser be turned off when using the sight?
Yes, it is possible to turn off the laser when using the red dot sight. There is no need to use both of these.
Can it be installed on AR15?
Yes, it can be installed on any AR15 variation within minutes. This is a simple and easy process that can be completed by anyone.
Which magnification is implemented?
New owners will get 3 times magnification which is one of the most desirable for a large number of users.
Is this sight immune to fog and rain?
The sight and the laser are both completely immune to fog and water. It can be used when it rains or snows. There must be no issues.
Who this is for: People who want red dot sight with a laser will love this option.
Why I like it: I like this kit because the manufacturer includes a lot of elements inside. I also like the laser sight and 3 times magnification.
Best sights for KSG — Buyer’s Guide
What is KSG?
KSG is a shotgun, pump-action weapon with 12 gauge (KSG 12 gauge). It was developed by Kel-Tec and it is very powerful. It uses 2 magazines and a user can switch between them manually. This weapon can hold 7 shells of 70 mm or 6 when 76 mm versions are used. Users can choose according to their needs.
This shotgun is 26.1 inches long and the barrel itself is 18.5 inches long. The weight is 6.9 pounds. I know that this weapon has been used in France, the United Kingdom, and South Korea. It is a professional weapon with great accuracy. However, the Kel-Tec KSG has Problems that you should be aware of.
How to choose a sight for KSG?
When looking for the best sight for KSG a person should consider a few things. Obviously, I must say that a compatible sight is the first thing and the most important one. All the sights above are compatible with this shotgun and come with a simple installation that can last for seconds.
The next most important thing in choosing Kel-Tec KSG sights is the MOA. A higher number means that the sight is more suitable for close distance targets. A lower number means that the dot is smaller and suitable for long-distance targets. 4-8MOA are the most common and the most appealing.
Magnification should be considered as well. It should be 1-4 and ideal is 3 times. I personally like this magnification in this case scenario. Keep in mind that KSG is a close-range weapon so getting a high magnification is useless[3]https://en.wikipedia.org/wiki/Kel-Tec_KSG.
The power source should be considered. Users can choose between a battery and a tritium. The battery must be replaced and last 50.000 hours. But it offers bright colors and brightness can be adjusted. Tritium lasts 12 years and there is no maintenance at all but brightness isn’t high.
What are the best Kel-Tec KSG accessories?
- Red Dot Sights
- Muzzle Breaks
- Extended Selector Switches
Red dot sights are the most popular Kel-Tec KSG accessories. They make it easier to aim your shotgun accurately, and they’re especially useful in low-light conditions. Red dot sights are my personal favorite Kel-Tec KSG upgrades.
Muzzle breaks are also popular accessories for the Kel-Tec KSG. They reduce recoil and muzzle flash, making it easier to shoot accurately. A scope on a shotgun can also make it more accurate from longer distances!
Extended selector switches make it easier to switch between firing modes, and pump-action grips make it easier to grip the shotgun pump when you’re shooting quickly. This is what makes them one of the more popular Kel Tec KSG improvements.
Benefits of Using A Red Dot on KSG
If you’re still on the fence, here are some benefits of using a red dot sight on a KSG shotgun:
- Improved accuracy: A red dot sight makes it easier to aim accurately, especially in low-light conditions or when shooting at moving targets. The dot is superimposed on the target, making it easier to aim precisely.
- Faster target acquisition: The red dot sight allows the shooter to acquire targets more quickly than with iron sights. This is especially useful in situations where quick reflexes are needed, such as in self-defense or tactical shooting.
- Greater flexibility: The KSG is a versatile shotgun that can be used for a variety of purposes, from hunting to home defense. A red dot sight allows the shooter to quickly adjust to different shooting situations and distances, making the KSG even more versatile.
- Reduced eye strain: Iron sights can be difficult to use for extended periods, especially for shooters with aging eyes. A red dot sight is easier on the eyes, reducing eye strain and fatigue.
- Improved confidence: Shooting with a red dot sight can give the shooter more confidence in their abilities. Knowing that you can quickly and accurately acquire targets can improve your overall shooting performance and enjoyment.
Red dot sights aren’t for everyone, but for most people they are a total game changer!
