How to Choose the Best Red Dot for AR15

Best Red Dot for AR15 (2)

Red dot sights are always a great accompaniment for modern rifles like the AR-15. They provide the consistency and speed that you may not get if you are just going to rely on your iron sight. It would be great if you would spare some money to invest in this device, especially if you are serious if your hobby. They can make the difference, regardless of the application.

But how should you choose the right red dot for your firearm? Are there any factors that you should pay attention? Well, the next section will teach you the ropes. Let's start.

Durability

Overall, a red dot sight should be as durable as your rifle. If you want to take this device outdoors, it should have impervious construction. Fog, moisture, dust, and other external detriments must not easily penetrate its housing. Otherwise, the circuits inside would be damaged.

Furthermore, the housing should be resistant to recoils as well. AR-15 rifles have notoriously strong recoils. Therefore, the scope should be rugged enough to keep all of its parts in place. Of course, this factor is dependent on the integrity of the mounting system. If the scope is compatible with the standard Picatinny or Weaver rails, then things are right for you already.

If the red dot sight can be mounted snugly, the stability and precision of your shots won't be affected. You can gain quick target acquisitions since the view is not wobbly and flimsy.

The Reticle

The size of the reticle is another crucial factor that you should consider when choosing a red dot sight. Some reflex sights offer a fixed size while others will let you adjust them. These two options are great. Just take which one do you think can give you more versatility and comfort in the field.

Also, don't forget that the reticle should have adjustable brightness. In this way, the red dot sight can adapt to extremely bright conditions. Ordinary scopes have reticles that quickly wash out during daylight conditions. That's not a good thing at all. For better results, the sight should produce a reticle that can shine brightly, regardless of the illumination. Ideally, it should also work during the night, too.

Don't worry if the red dot appears to be fuzzy. That is normal. It is quite impossible to find a reticle that has a clear and detailed outline.

Batteries

Of course, red dot sights will not operate if you won't insert its batteries. These are electronic devices after all. Unfortunately, all red dot sights have different battery capacities. Some of them can last a day without switching off, while others have limited hours of use. Logically, you should opt for those units that can operate for an extended period. They can provide a reliable service that is necessary for police and tactical personnel.

Despite this, you should never be abusive and clumsy. If you are done using, you should already switch off the device. If you tend to be forgetful, then you must get a unit that has an automatic shutdown feature. Also, take note that batteries quickly discharges during cold weather.

Final Verdict

Red dot sights are useful amenities. They can drastically improve the performance and accuracy of AR-15 rifles and other firearms. Your handgun can even benefit from them because of the extra precision they can provide.

All the red dot sights that I have featured here are capable of doing these feats and more, especially if you are going to choose the Vortex Optics Sparc 2. The latter is my best red dot for AR15. It is incredibly versatile and stable. It is very functional, too. All the necessary adjustments, such as for the brightness, windage, and elevation are on this device. The housing and lenses are very durable, too. It is not a surprise anymore if professionals like this reflex sight.
