Put two scopes side by side on a table. Pick one that costs half what your rifle costs and chose another that costs three times what your rifle cost?  What’s the difference? You certainly can’t tell from the outside. In fact, the cheaper scope may have a slicker finish and more buttons and knobs. Why do some scopes cost so much more than others?

Like many other things, what you see is not always what you get. The major differences in scopes, especially why the prices differ so much, are completely out of sight. It is the internal differences that make the difference in scope quality and price. Understanding how scopes are made, how they work, and where manufacturers cut costs is the key to finding real value in a rifle scope.

Purchasing a scope for that new rifle can be confusing, frustrating, and expensive if you don’t understand rifle scopes and how to judge quality. There is a lot more to finding a good value rifle scope than looking through the lens in the sporting goods store and counting the cobwebs on the mounted antelope display.

How Rifle Scopes Work – What You Can’t See

The part of your rifle scope that you can easily see hides the real important parts. What you can see on a typical rifle scope is important. They can give you a few clues about the quality of the internal workings, but you must be sharp to catch the subtle signs. Most scopes have external parts that include:

Your scope may have other knobs and adjustments. Scopes with illuminated reticles often have a knob to control the brightness and even the style of reticle you see in the scope. The takeaway from this information is the understanding that for every knob and adjustment on the tube of your scope, there is an associated increase in the complexity of the internal mechanisms. Complex mechanisms mean more places for failure and tighter tolerances to achieve acceptable accuracy.

A Simple Fixed Magnification Scope

The simplest of all designs for a rifle scope is the fixed magnification scope. You might think that all you need is a set of lenses fixed in the correct position. What could be more stable and less prone to inaccuracy or failure?

In truth, even fixed magnification scopes have complex internal workings. Inside the outer scope tube is another tube called the erector. This tube holds at least one other lens that turns the target image upright.  

The elevation turret and the windage turret attach to screws that move the erector tube, allowing you to correct the scope for windage and elevation. The quality of the mechanism on the windage and elevation adjustments greatly affects the scope’s accuracy. The more precise this mechanism, the better the accuracy of the scope.

Variable Magnification – Getting Close and Even Closer

To add complexity to a complex situation, many shooters opt for a variable magnification scope. The ability to dial in a bigger picture of your target without moving is a huge advantage in some situations. The problem is the ability to vary the magnification requires growing the complexity of the inner workings of your scope grow by many orders of magnitude.

We already know that the inner tube of your scope, the erector tube, is adjustable for windage and elevation. To gain the ability to vary the magnification, that erector tube must move back and forth inside the outer tube.

This additional range of movement adds a new dimension of mechanisms inside the scope tube. Scope makers walk a fine line between weight, ruggedness, and recoil. Build a lightweight scope, and you risk damaging the erector mechanisms from recoil. Build a robust system, and the scope gets so heavy it is almost unusable. You begin to see the problem for scope manufacturers.

Add to the problems building an erector mechanism that is also finely machined to keep the scope’s accuracy within tolerances. The more accurate and robust the erector mechanism, typically, the more expensive the scope.

A Multitude of Other Adjustments

Those are the basics of most rifle scopes. If you want parallax adjustments critical to long-range precision shooting, the mechanisms take another jump in complexity. Add diopter adjustments to the mix, and it is almost unimaginable how the mechanisms inside that 30mm tube operate.

It becomes easy to see that just the mechanics of a high-quality scope can add a level of expense. Scope makers with a reputation for building rugged, reliable, and accurate rifle scopes have spent years developing the expertise to craft the mechanisms that drive their scopes.

The Other Factors of Scope Cost

We haven’t started to discuss the optical components of a good rifle scope or the other mechanical issues such as waterproofing, fog proofing and shock proofing. Let’s look at all the other factors that differentiate a cheap scope from an expensive scope.

Optics and Glass

The lenses and other glass that go into a scope are critical to how the scope performs. In general, rifle shooters talk in terms of factors such as:

Materials and Workmanship

The quality of the materials used to construct the scope and the care taken when crafting the intricate parts matter almost as much as the quality of the glass and the design of the internal workings. These two aspects of the scopes assembly can be hard to ascertain and judge.

We must rely on the manufacturer’s word about the quality of the materials they use. It is almost impossible to tell inferior aluminum alloy from high-quality aluminum alloy outside a laboratory.

Judging the quality of the machining and the tightness of the tolerances inside the scope requires disassembling the scope. Disassembling your $500 scopes isn’t something I recommend for anyone. How then do we judge these factors?  There are some tricks to try.

Do Your Due Diligence – Research can be your best tool. The internet has brought a wealth of information to your fingertips. Look at the reviews of the scope. Read the various shooting forums to see what other shooters are saying. The manufacturer’s reputation and other shooters are good indicators of what to expect from a scope.

Tale-Tell Signs of Scope Quality – There are some subtle signs you can check for right in the store that give clues to a scopes internal qualities. Before you even look through a scope check for these indicators that the internal workings are less than optimal

If Possible, take it to the Field – One great way to figure out if a scope is up to the task you set for it is to put it on a rifle and shoot it. Poorly made scopes will reveal themselves quickly. The most obvious sign is a scope that won’t hold zero. Next is a scope that doesn’t perform optically as it runs through its paces. Lastly, the recoil of a large caliber hunting rifle will test the ruggedness and robustness of the internal workings.

Unfortunately, most retailers won’t let a scope go out for a test drive. The only way to get some of the tests is to buy the scope and take it for a spin. If the warranty is good and your dealer is reputable, this probably won’t be a problem. However, beware. You may end up with no cash, a broken scope, and a large dose of frustration.

At The End – Our Recommendations

There are gems among the rocks out there in the scope buying world. New manufacturers are coming online, and occasionally, one of them builds excellent scopes at a reasonable price. Finding that balance of value, features and performance should be your goal. Here are my tips for finding your scope.

Don’t expect to get what you are willing to pay for – Never expect to get the performance of a $3,000 scope from a $300 bargain. It’s just not going to happen

Make good decisions – Know what you want from the scope you buy. Different types of shooting require different scopes. Buying a scope that doesn’t meet your requirements just because it is a good deal doesn’t make sense. You will eventually get frustrated and be disappointed.

Understand how a scope works and what to look for – I get frustrated in some retail stores when I talk to a salesperson who obviously knows nothing about how scope construction or how they work. Don’t rely on retails store staff. They are there to sell products, not give technical advice.

Watch for the rare gem among the trash – Sometimes, you will find that outstanding rifle scope where you least expect it. Reading the shooting forums is a good place to learn about these opportunities.

Buy what you know – Shopping known manufacturers with good reputations and whose scopes get good reviews and remarks is your best insurance against making a bad choice. Remember, the adage you get what you pay for is often quite true.

Good Scopes Cost More – Period

Everything that goes into a scope to make it a quality product has an associated cost. Better material, tighter tolerances, design, and engineering all directly impact the cost of that scope. From a purely financial standpoint, better scopes cost more to make. Therefore, they have a higher price tag.
