What factors should you consider when purchasing a red dot sight for your weapon?

Red dots are a great addition to your shooting activity gear as they ensure rapid target acquisition and pinpoint accuracy when you are out hunting, during sports shooting and even when you are trying to protect yourself and your home from predators. The following factors are important to consider when you are trying to purchase the best quality red dot for your hunting weapon;

Size of the Red Dot

Generally, the size of the red dot should match the size of your weapon. Rifles would work well with larger red dots while smaller handguns would work better with smaller red dots. In addition to that, smaller red dots are more compact and lighter which significantly reduces equipment bulk in your outdoor activity gear.

Reticle Size

The reticle size generally depends on the types of shots that you will be taking and the distance from your shooting position to your target. A smaller reticle is ideal for taking more accurate shots at longer distances but it may be harder to see while larger reticles are suitable for close-range shots and for newer shooters as it is easier to use.

Battery performance

Generally, you are at a higher advantage when you settle for a red dot that features readily available batteries that one that runs on special order batteries. Also, you would rather settle for a red dot with a prolonged battery life as it allows for the longest possible operating times.

Night Vision Compatibility

Hunting and shooting in low light conditions such as dusk and dawn would require you to purchase a red dot that has night vision compatibility so that you can see clearly in the dark.


Generally, red dot sights ensure fast target identification alongside rapid and accurate target acquisition. Mid-range red dot sights under $500 are excellent options if you are looking to benefit from high-quality optics. They provide you with a decent sight picture and they have a sturdy construction that ensures they are rugged enough for use in all kinds of environments. Among the five, the best overall is the Vortex Strikefire Gen 2 red dot sight which allows you to access an immersive observation experience.
