Four Key Benefits to Using a Red Dot Sight For an AR 15

1. Fast Target Acquisition:

Once you get the target, you must aim quickly using the red dot ambit. The red dot ambit allows you more convenience and accuracy due to the fact that you do not need to align a front and rear sight on a target. Also, the US military applies red dot sights as a method of increasing the effectiveness of soldiers in armed combat. In short, red dot sights enables you to shoot fast at targets and get more efficient results.

2. Wider Field of View: 

It is a fact that red dot scopes have a wide field of perspective compared to tube style scopes. By using this feature, it allows you to take shots at longer distances. You must keep in mind that the magnification limits the field of perspective which tube style scopes amplify. At the same time, tube style scopes limits the usefulness of small-arm at shorter distances. Moreover, red dot scopes do not have any magnification that is suitable for short or medium ambit shooting.

3. Unlimited Eye Relief:

To properly apply an ambit or open sights, you must mount the firearm close to your eye measuring up to 2 or 3 inches. By doing this, you can properly utilize traditional scopes that typically have eye alleviation distances. But always remember that red scopes have unlimited eye alleviation so you must bring the sight close to your face and aim the firearm without hesitation.

4. Low Light Usage:

The red dot sight applies battery power or special light aggregators to project the dot onto the glass. This bright red dot is visible to you even in low light situations. In low-light shooting, the black cross hairs of tube-style scopes cannot be seen. Furthermore, you can use open sights to properly align in low light shooting thus giving you more accurate shooting results.

How to Choose a Red Dot Sight

Red dot sights can aid you in shooting a precise and accurate shot. It can also help a lot in fast and very close shooting. Here are some tips on choosing a perfect Red Dot Sight:

1. Price does not always equate to quality. 

Make sure to check if the product you wish to purchase is legitimate. You can always read product reviews on the internet to make sure. Advertising could be deceiving so you have to be smart in picking your red dot sight.

For airsoft, paintball, etc. enthusiasts or those who use their guns for plinking, less expensive ones will work out fine. For people who use higher caliber guns, I would recommend spending a bit more for a red dot sight. But again, the price doesn’t guarantee the quality of the product.

2. Consider the gun you want to buy the Red Dot Sight for. 

Make sure that it will be compatible with your gun. Your gun could lose effectiveness if the wrong red dot sight is bought.

3. Choose the right size and reticle. 

Red dot sights come in various sizes. Some dots can even be adjusted. You should consider the size of your gun as well as how much room or space you have. Usually dots with 4 or 5 MOA (minute of angle; 1MOA = 1in at 100 yd) are perfect. Larger dots mean you can find your target quicker and shoot your target faster.

4. Choose the right weight. 

Size is not the only thing we should consider. The weight of a red dot sight can also affect the accuracy of your shot. A heavier red dot sight could have a bearing with your grip and handling.

5. Mounting and adjustment. 

Mounting and adjusting your red dot sight is another crucial thing for an accurate and precise shot. Once you get the hang of it, I can assure you will hit your targets dead on.

6. Long battery life.

Red dot sights are battery powered. Without power, no red dots will not be visible. Usually, red dot sights have long battery life (some can even last for thousands of hours or equivalent to 5 years or more); despite that, remember to turn it off when not in use. Additional tip: cold weather can drain battery power. Make sure you have spare batteries for your red dot sights. Carrying small batteries won’t be a hassle.

7. Co-witnessing. 

When red dot sights are used in night vision, the red light usually becomes very faint or almost invisible. Co-witnesses are usually used by military. While most red dot sights can be used in night vision, these can serve as back-ups in case your red dot sight fails you. At an appropriate height, you can use and see your iron sights with or without the red dot.

Choosing the right red dot sight could significantly improve your accuracy, precision, and speed whether you are using it for combat, hunting, or even just plinking. Do your proper research and do not overspend. Make sure the one you are going to purchase will really be worth your money.

I hope this helps you find the right dot for your gun! Happy shooting!
