Buyer’s Guide

#Things to consider while buying the best red dot sight

There are so many aspects of a red dot sight, that it can be really overwhelming to select the best one available in the market as per your requirement.

1. Reticle size

At the surface level, it might seem just a simple red dot, but it does come in various sizes. MOA is the official unit when it comes to the reticle size. 1 MOA equals to 1.047” at 100 yards which is often taken as 1” for simplicity. Reticle size ranges from as low as 1 MOA to 9 MOA. The smaller the size is the better will be the accuracy. A small size reticle size will make it easy for you to target your shot with ease and better accuracy, whereas, the bigger reticles might make it difficult for you to focus on your target with clarity.

2. Red Dot size

Red dot size is the most important factor to consider. It comes in three general size categories: Mini, compact and full-size. 

  • Mini red dot: Miniature red dot size is most commonly found on small sized weapon like pistols and handguns. These are extremely lightweight red dot and are very suitable to use for close combat situations. It won’t be of much help in moderate distant targets.
  • Compact size: This is a medium-size red dot which is about 20-25mm. You can use these with most of the rifles but these don’t really offer the true red dot sight experience. They are pretty convenient to use but the small battery and intensity issues are also very common among the users.
  • Full-sized: These are the biggest of the lot with an average size of 26mm. They are also heaviest among the three, thus not the easiest to carry.

3. Magnifier compatibility

Many shooters require a magnifier along with their red dot sight to shoot far away targets. Compact size and full size red dot sights are often compatible with multiple magnifiers. So if you need to extend your shooting range from a typical red dot sight range, be sure to check the magnifier compatibility of the red dot sight you choose for yourself.

4. Price

The budget is a very common constraint for many shooters as most of the shooting accessories are highly-priced. Always define your budget range before jumping-in in the market to search the best red dot sight for yourself.

5. Durability

The durability of any red dot sight is a very important aspect for all the professional shooters. While searching online the best red dot sight, make sure you find words like waterproof, submersible, shockproof, and nitrogen purged.

Though these durability features come at a high cost, they are definitely worth the price as you would not want your sights to be worn-out after a few uses only.

6. Battery life

The battery life you need for your red dot sight will totally depend on your usage of the tool. If you are a professional or a law enforcement agent you would need a really long battery life so it doesn’t run out in any critical situation.

However, if you’re just a hobbyist you can use your firearm however you want with any amount of battery life as you want.

7. Other factors

  • Night vision: This feature of red dot sights will help you see and acquire your target with better accuracy during the night. It is a very big advantage for those shooting in multiple lighting conditions.
  • Brightness settings: Many red dot sights offer multiple brightness settings which is a great feature as it ensures adequate eye relief and comfort while using the sight.
  • Brand value: The brand value of any shooting gear matters a lot while making a purchase as it tells a lot about the products durability, build quality and also the after sales service the brand provides.


As there are so many red dot sight manufacturers in the market, it can seem daunting at times to choose the best red dot sight. I have tried to cover most of the aspects of a red dot sight along with detailed reviews of the best red dot sights available in the market. Moreover, you can always check user reviews before buying any shooting accessories to have a clear opinion beforehand.
