Buying Guide Of Best Cheap ar 15 Scope – Things To Consider

Scopes priced under $100 are notorious for being poorly made and having inferior optical quality. With the exception of a few, some of which are listed above. That being said, you have to be very careful when selecting a budget ar 15 scope. Here are some of the things you should look at.

1. Magnification Power

When it comes to magnification, more is not always better. The opposite is true, for scopes priced under $100. Scopes in this price point are usually designed for short to medium-range precise shooting and their magnification reflects this.


Ideally, a maximum of 9x magnification levels is enough for this purpose. A higher magnification at this price point might be overkill.

2. Eye relief


Eye relief is an essential factor to consider. Having Eye relief of less than 3 inches may be disastrous. The short eye relief may cause you eye injury when your rifle bucks from recoil. Thus a more extended eye relief of not less than 3 inches is ideal. Some scope offers unlimited eye relief which let you to sight the target more fast. This unlimited eye relief is best suited for target shooters.

3. The reticle

There are many different reticle options, from illuminated, BDC, mil-dot to the duplex reticle. Given the price range, don’t expect any fancy or sophisticated reticles. However, an illuminated reticle will be a bonus for your ar 15 rifle.

An illuminated reticle allows you to hunt even when the sun goes down or before it comes up.

4. Housing

The exterior casing of a scope protects the interior components from damage. As such, it should be tough enough to withstand weather conditions. A scope made of aluminum will be an ideal choice.

Aluminum is both sturdy and lightweight, which is what you want. Also, the housing should be well protected from moisture and fog. Nitrogen purged interior is an essential feature for any scope. And so are O-ring seals that prevent water from entering the scope.

5. Lenses

Considering the price point, don’t expect any fancy technologies when it comes to lens coating. However, at the bare minimum, the scope should have multicoated lenses. This will help produce sharp and clear images.

6. Turrets

In this price range turret quality isn’t the best. Most have 1MOA and 1/2MOA adjustments. However, some come with either ¼ MOA or 3MOA adjustments. Consider the elevation turrets adjustment knob quality if you want functionality beyond maintaining zero.


The AR 15 rifle is a versatile one that can be used both for hunting and tactical purpose. Also, there are many scopes designed for this specific type of gun. Some cost hundreds of dollars while others, such as the ones listed above, cost less than $100.

Nonetheless, the best scope for ar 15 under $100 is the one that best suits you and your shooting style. It is essential to evaluate a scope’s features before splashing money on it irrespective of how much it is you are spending on it.
