Experts can’t even guarantee that the cheapest scopes are low quality and the expensive scopes are the highest quality that can deliver the best output.
When looking for a scope, the other factors are decided depending on what you utilize the scope for.
Purchasing a cheap or budget-friendly scope for your AR-15 rifles does not mean that it will offer lower performance, but rather that they offer optimum performance with fewer features.

Factors to Consider when Buying the Best AR-15 Scope Under $100
Choosing the right scope for your AR-15 rifle is a little difficult at the moment because nowadays there are different models that come from different brands in the market with different ranges of prices.
Such as all other scopes, the low-cost or cheap scope for the AR-15 varies based on brand, type, style, design, technology, mechanism, and some other features.
So in the segment, we’ve revealed the important and prominent factors to consider while buying the best AR-15 scope under $100.
Durability & Adjustability
The first thing you should consider about the scope is its construction and material work.
Of course, the best scope should be made out of premium-grade materials and comes with multi-proof (waterproof, shockproof, fog-proof, scratch-proof) technology to prevent the device from various damages.
If you want flawless and uninterrupted performance, choose the scope that comes with adjustable dials and knobs.
And the elevation and windage turrets of the scope should be effortless to turn also it should come with the perfect size to provide swift target acquisition.
Generally, AR-15 scope comes with different types of reticles, named duplex reticle, mil-dot reticle, illuminated reticle, non-illuminated reticle, and BDC reticle.
These are perfectly suitable for your several preferences and applications. And there are two reticle options you should choose from Triplex or Red / Green-Dot.
Standard illuminated reticles are much handy especially in the low visible condition and pitch darkness, because of this most of the users go for the illuminated reticle rather than non-illuminated reticle.
More so, illuminated reticles enhance the lighting conditions by brilliantly transmitting the light. On the other hand, red dot scopes are wanted by the beginners to utilize the scope with minimal functions in the field of hunting or shooting.
Aside from this, you should focus on the settings of reticles which are equipped with First Focal Plane (FFP) or Second Focal Plane (SFP).
If you are going to utilize the scope for hunting, shooting, and tactical applications, it’s important to consider the magnification level of the device, which is one of the prime factors in scope purchase.
Commonly, the magnification range of the scope has two numbers that refer to the diameter of the optical lens and level of the scope.
It is a common fact that a wider objective lens with multi-coated technology provides a smoother and clearer field of view. There are only two types of magnification that are “fixed” and “variable” in the scope.
As its name implies, fixed type magnifications render only a certain range of magnification, which are suitable and beneficial only for significant situations. Aside from this, scope with fixed magnification operates for a long time because it comes with lower components.
The variable type magnification scope is more flexible thus it allows the user to frequently change the range depending on the situation and personal preference.
As well as, it provides swift target acquisition and precision. The feedback of this type is, there is a chance to be easily fragile since scope comes with extra components.
A standard and long eye relief ensures protection depending on the distance between your eyes and the ocular, thus protecting your eyes and eyebrows from injuries during hunting or shooting.
Experts generally recommend big eye relief because they allow you to see the target accurately without hurting your eyes. Due to industrial growth, most of the scopes currently being manufactured have adjustable eye reliefs, which provide better results in the field.
Parallax on riflescope indicates the image distortions you get when operating on a hunting field. All the high-powered scopes are having parallax options to enhance the shooting and provide precision.
To avoid image distortion when viewing the target by scope, it should be incorporated with a parallax-free adjustment aspect, thereby ensuring perfect aiming and shooting.
Size and Weight
You must consider the size and weight of the scope and it depends upon your shooting style and preferences. The compact riflescope is the best option for the person who uses the scope for the short-range and mid-range hunting.
Or else if you want to utilize the scope for long-range or heavy performance then you need to go for a bit heavy device.
But when it comes to choosing the scope for AR-15 rifles, the first thing to focus on is whether the scope fits easily with your top platform of AR-15.
Truly it’s a difficult task to choose the best product from the thousands of options, which are similar to each other.
