You are currently viewing Choosing the Best Scope for AR 15 under $100 – Any Good Options?

Choosing a scope for your AR 15 can be a challenge. There are more brands out there, as well as more models. Some of them appear to have identical features, while others have a series of particularities. The price will also come in as a serious consideration. So, what is the best scope for AR 15 under $100?

The answer is quite broad and depends on a series of different aspects. Instead, you should ask yourself about the best scope in your price range. Or maybe find out what the best scope is based on your actual necessities.

It is worth noting that there is no such thing as a perfect scope. There is no such thing as a scope that will be best for everything. Some scopes are ideal for aiming at shooting at 100 yards, while others are more suitable for 500 yards.

Do you compete in events? Do you kill gophers to train? Are you about to go on a four-day hunting trip with your tent? How about an army scope? Different needs come with different requirements, yet some scopes can still make the difference.

What to look for when getting a new scope for AR 15 under $100?

Knowing what to look for in a scope for your AR will lead you in the right direction.

Consider the quality standards

No matter what type you need or what you need it for, it is highly recommended to opt for a scope designed by a popular manufacturer with a good reputation in the industry. Moreover, you get what you pay for – it does apply in this field because quality scopes will cost a lot more than a cheap useless design.

It does not mean that you have to spend $1,000 to get a quality scope. Instead, you simply have to assess your needs, decide what kind of performance you require, and find the best rapport for price and quality – value for money.

Check the size

There are no general rules when it comes to the size and weight of your scope. But then, it is worth noting that the AR 15 was designed to be lightweight and flexible. It has a compact built that makes handling a breeze.

As a general rule of thumb, you should follow the same standards for your scope. You do not want a bulky scope that will ruin the balance of your rifle, do you? It is all about making sense, but at the end of the day, there are no restrictions.

Try to figure out its durability

Scopes designed for anything else than practicing will require a rugged design. They will be exposed to wear and tear. They will take a good beating out there, regardless of how careful you are. Think about the rapid firing that may occur at times too.

All these uses might affect the zero point, hence the necessity of getting a scope that can maintain its point. At this level, you do not have to be a genius to realize that metallic components or other durable materials are much better than plain plastic.

A few must-have features

If you need a scope for tactical uses or random hunting sessions, you will have to deal with moving targets. Some of them will barely move until your location is disclosed, while others will run like there is no tomorrow. Small details make the difference then.

You must acquire your target at more distances, but you also need to keep an eye on it. From this point of view, a red dot sight feature is the main necessity. At the same time, holographic sights can also make a difference in such applications.

If shooting at a long-range is your main priority, immediate target acquisition is no longer vital for a successful adventure. In this case, minimal or moderate magnification should become your top considerations.

Keep an eye on its resistance to elements

Unless you only go hunting on hot sunny days or you practice in a covered area, your scope will deal with all kinds of weather conditions. Some scopes come with incorporated electronic circuits, meaning they require even more care.

There are a few different ways to look after them, but most importantly, make sure you invest in a scope that is both waterproof and fog proof. Such scopes come with a minus, though. If they have electronic circuits, they also require some power – usually, this source consists of one or more batteries. In other words, the available power is likely to become a concern too.

Become familiar with the main types of scopes

There are three general types of scopes out there:

  • Reflex sights – known as the red dot scopes
  • Holographic sights – a better range and a better field of view, but not too many brands or products out there
  • Riflescopes – they can have fixed or variable magnification

Now that you know what could make the difference when hunting the best scope for AR 15 under $100, what are the top-rated products out there?
