Here’s to the second Vortex champion in our list of best red dot sight for AR 15. Although it may be a bit expensive than the former version, it offers occasional hunters a more convenient and promising hunting experience.
The primary reason we’d recommend this great red dot sight to occasional hunters is the long battery life and the overall construction of this unit. It’s all set to deal with intensive rough and tough but not repeatedly.
You could expect its aluminum body to withstand a fair amount of bangs, falls, and thuds. The 7.5 ounces body that measures 5.6 x 4.65 x 2.7 inches in length, width, and height offer decent resistance against shocks. You needn’t worry when the impact of recoil is ever so slightly extra.
Plus, the O-rings keep the dust from penetrating the base. Thus, bringing about a waterproof performance.
The battery life is similar to Crossfire. You get about 50000 hours in the lowest settings. But in the highest, you get about 700 hours.
We love the fact that you get about ten different illumination settings. And with the lowest two, you can benefit from the night-vision functionality of this red dot sight.
The windage and elevation controls are found on the top and the left side, respectively. Their positioning is highly convenient in terms of a rifle operators’ hand reach.

Moreover, with the package, you will receive a complete multi-height mount system, triple-A batteries, a T10 Torx wrench, and a rubber cover with a flip-up lens cap. Although the unit’s label price appears a bit expensive, we believe including these accessories does justice to the $200 figure.

But then there may be a question lingering at the back of your mind, why didn’t Strikefire II made it to our best pick? What keeps this ever-so-versatile red dot sight back?
Well, it’s the precision and 12-hour shutdown mechanism that keeps it back. Comparing this to Vortex’s best manufacturers of all times, i.e., Crossfire, Strikefire II has a 4 MOA dot which may be a little too large for precision shooting, particularly for intermediate distances.
As for the 12-hour automatic shutdown, it saves the battery life and extends it admirably. You can expect Crossfire to deliver a battery time of 80,000 hours, while most others only offer 50,000 hours. At the lowest settings, it delivers 7000 hours. However, the auto-off function proves to be irritable for frequent and intensive users. An auto-on functionality would’ve been great.

Red Dot Sight Buyer’s Guide – How to Choose a Red Dot Sights?
Alright, so now you know the top seven red dot sights you can get for your AR 15. But how do you narrow down this massive pool of goodness to one? How do you pick one that’s best for you?
We guessed such a question popping up in a serious AR 15 red dot user’s mind, and so we kept this comprehensive buying guide all set and ready. Read on to unravel what exactly you should look for when choosing a red dot sight for your AR 15.
The very first aspect that you need to consider is the size of the scope tube. Fundamentally, it is the scope tube that holds all components in their proper place. Plus, it determines the size of rings and bases.
It comes in two sizes, including:
- One inch
- 30 mm
For a one-inch scope tube, you will require one ring and bases. And the same applies to 30 mm. Any non-corresponding components will make the installation process difficult.
Next, you need to assess the quality of the red dot. Check if the red dot sights that you wish to purchase feature a durable exterior or not.
Usually, a red dot sights body features aluminum material or a similar metal alloy, which works fine. For durability, you can check out review claims, as well as the company’s stance on the subject. If they promise durability and even offer a warranty plan, you’re good to go with your selected option.
Another preference that you need to keep in check is the weight relative to the size. The smaller and lighter the red dot sight, the better it will be. Ideally, you should look for a red dot sight that weighs four ounces or less.
Weatherproof exterior or weather resistance is second in line when it comes to quality checks. Since you will have a lot of outdoor interaction and activity, having a weatherproof and fog proof body is an absolute necessity.
Otherwise, excessive exposure to moisture or heat may adversely impact the body. And thus, consequently affecting the performance of the red dot optics. Given you’ll be spending a decent amount of money, we’d advise you to keep weather resistance and fog proof as a primary need when buying a red dot sight for AR 15, particularly if you use your rifle a lot.
Field of View
Field of View, also known as FOV, refers to the measured area visible to your eye as you look through your optic. On average, a user could visualize everything on the left and right situated about 100 yards away through the FOV.
To understand how this works, you ought to know that there’s another important parameter that you will always have to consider, i.e., magnification—the greater the magnification, the lesser the field of view (which is not good). Increasing the magnification extensively brings about the tunneling effect, which may mess up your aim.
Hence, for a more accurate shot at your target, it’s best to keep the magnification between 1x to 2.5x. And this is particularly true if you want are aiming between 50 – 150 yards for quick target acquisition speed.
Power Ring of a red dot sight refers to the control knob on your scope that allows you to adjust magnification (or, it doesn’t).
Technically, there are two types of power rings. These include:
- Fixed Power Rings
- Adjustable power rings
If you are comfortable working with a fixed magnification, the first one will do fine. However, if you need to adjust your view now and then, you may want to get a red dot sight with an adjustable power ring.
Price & Brand
Price and brand of the red dot sight have a direct relation with the quality and performance. By the rule of the thumb, the more you spend, the better performance you’ll get. And the more trusting and reputable the brand is, the longer the red dot sight’s accuracy will last. Some of the names that we trust include Holosun, Vortex, Aimpoint red dots.
Conclusively, having the best red dot sight for AR-15 with fixed front sight is a must if you wish to up the level of accuracy and thrill you have in your hunting sessions. It does not only contribute to your expertise level but also assists you with your learning experience. With that said, if multiple options leave you baffled, we’d recommend you to either try Crossfire or Strikefire red dot. But if you wish to invest in a good red dot sight specific to your needs, then compare your needs to strong suits of the red dot sights reviewed above.
Will the front sight on an AR-15 interfere with a red dot?
Nope, it wouldn’t! In some cases, the users prefer dismounting the front sight when equipping the rifle with a red dot. However, in this case, you have a fixed front sight. So, that option is out-ruled. Irrespective of that, you can still have both on your rifle and operate without any interruptions or worry.
Is there an ideal red dot sight for AR-15?
Well, we’ve mentioned all the very best red dot sights for AR-15 up above. However, if you’d ask us to pick just one from the many, then we’d recommend Vortex Crossfire! The latter is economical and super convenient to use for both beginners and experts. The accuracy, without a doubt, is incomparable!
Should I opt for a scope or red dot for my AR?
It depends on your usage. Generally, both scopes and red dots come into use for enhancing the accuracy of AR 15.
However, to improve accuracy for a distance of 0 to 50 yards, you should opt for a red dot sight. But to improve accuracy for 50-100 yards or more, then a magnified scope will serve your needs better.
Should I opt for a red dot or a green dot?
Usually, it’s the red dot that comes into use. And that’s because it’s easy to locate. It’s easier for the eye to identify the red dot as compared to the green. So, in both low-light conditions as well as daytime, the red dot works great. However, if camouflaging or blending your aim in the environment is the concern, you should opt for a green dot.
