When you want to use your AR-15 for long-range applications that would involve shooting very far targets, then the most important thing that you have to consider is the range of magnification.
The magnification would let you see objects and targets that are located at a very far distance. Of course, the higher the magnification, the farther you would be able to see too.

2. Light Weight
The AR-15 rifle type is widely known and used because it has one of the lightest weights when compared to the other types of rifles.
Since it has very lightweight only, it is not right to mount a very heavy scope on top of it. Considering the weight that the AR-15 has, the weight of the long-range scope that must get should be light too.
If you mount a long-range scope that is heavy on top of it, you are going to have shots that would not accurately and precisely hit your targets because your AR-15 would somehow be outbalanced.

To be sure that you would be able to perform well while not damaging your AR-15, just choose a lightweight long-range scope.
3. Resistance to Weather Conditions
Long-range hunting and shooting are often done outside—for this reason; you have to buy a long-range scope that is designed to have the maximum protection against different conditions out there.
The resistance of your long-range scope against different weather conditions must be considered too. If you do not consider that factor, your scope might break or get damaged sooner.

Some of the properties that make a long-range scope protected are nitrogen purging, nitrogen filling, complete sealing, and O-ring sealing.
4. Price and Quality
One of the first things that people check when they are buying something is the price. When buying a long-range scope, you should consider it too because you obviously do not want to break your bank account.
Nowadays, there are long-range scopes for AR-15 that are affordable. If you have the time and luxury, try to search for those ones since they are also proven to be reliable.
You do not have to buy the most expensive one because it does not guarantee you that you are going to have a long-range scope that would perform well at all times.
You have to check the price and quality at the same time to make sure that you spend your money wisely.
The optics is another factor that you have to look into when buying a long-range scope. The main reason why you are buying a long-range scope is to have a good view or sight of distances that cannot be seen with the human eye, so it is of paramount importance that you consider having a good quality of optics for you to see good quality views and sights too.
One of the things that you must check is having fully multi-coated optics. Having a reticle type that is directly etched on the glass of the lenses is a good design to include in the optics, too—this would ensure that the reticle does not fade over time. Another thing that you have to check has scratch-resistant lenses.
