It is no secret that an illuminated reticle will offer you better clarity in certain situations. An example is at dawn and at dusk – when the ambient light is not as clear as it should be.

Another advantage of this reticle type is that it provides you with good contrast against a wider range of backgrounds. The discouraging aspect though is that it requires batteries to run. This removes such scopes from the favorites list of several users.

Best Ruger AR 556 Scope Buying Guide

Here for you are a few tips that will help you make the best of your purchase. Understanding the main components of your scope will help you to determine the best fit for your needs.

So let’s check them out:

Budget

Before we go any further, let’s face it: your budget will be your main factor when you examine the scopes. The price range for scopes can range from less than $100 to something requiring a mortgage.

If you are in the high-quality scope market, you will be interested in the high-end products. That said, you can still get a decent level of quality at a much more reasonable price range.

Price does not directly translate to satisfaction, so taking a look at the rest of the details will help you get a decent fix for your scope needs.

Use

Once the budget is established, the most important factor to consider, even when you start looking for a scope, is exactly how you will use that rifle and scope.

Consider the distances you shoot and hunt. And consider the total weight. Then consider the complexity you really need for your scope.

Have a good idea when you start the buying process.

Although there are many types of scopes, there are basically two categories for the most common scopes:

  • Variable Scopes: Variable scopes are the most common. And they allow the user to adjust the magnification to meet their needs. These scopes are best used in situations where the user can take a proper view at varying distances.
  • Fixed Ranges: As the name suggests, the user can not adjust the magnification. These scopes are ideal for situations where the user generally uses the weapon in the same environment and distance each time.

While most of the items on this list only feature the variable scopes as they are the most practical, there are still some sub-categories that you need to look into:

Magnification

You should be able to determine the magnification values on the different scopes. You will see numbers like 2 × 30 or 3-9 × 32.

Here is what they mean:

The first digit is the level of magnification.

The second number corresponds to the diameter of the frontal lens (objective lens diameter).

If there is a range in the first number, for example, 3 to 9, this range is a variable extent whose magnification varies from 3 to 9.

If there is only one number in the first value, it is a fixed range, and the magnification is set to that number.

However, while you might believe that the best choice for rifle scopes is to choose a scope with maximum magnification, it is not always the case. Choose a scope magnification that matches the shooting style that best suits your needs.

Although there are many schools of thought on magnification, here is a very brief summary that should help you.

  • The 2 x – 4 x magnification range is good for shooting at a target within 170 yards.
  • The 4 x – 10 x magnification range is suitable for game up to 300 yards.
  • 10 x – 25 x are for extreme distances.

In any case, ensure that the scope offers you superior optical clarity at all magnifications. It should have an anti-reflective coating because you will get much better brightness with this coating as opposed to raw glass.

Lens Diameter

The objective lens allows the light to pass through the telescope and returns it to the ocular lens, this is the lens closest to the eye. Essentially, the larger the frontal lens, the more light it is allowed to enter the telescope.

Just be aware that the larger the diameter of the lens, the heavier the telescope.

Hence, an average sized lens is a good idea unless if you don’t mind a little extra weight.

Eye Relief

Eye relief is the distance from the back lens that your eye needs to see a complete image. The standard eye relief is about four inches.

Several scopes offer less. Be careful not to use a scope with a smaller eye relief if you use a stronger rifle.

Hence, go for a product with around four inches or more.

Tube Size

Basically, the tubes are available in two sizes: 30 mm and 1 inch. No size has any notable advantages over the other. The key is to know the size of your tube in order to buy the appropriate mounting rings.

So What’s The Best Ruger AR 556 Scope?

As you must know by now, the best scopes are those that are reliable and offer you the best optical clarity. Your AR 556 is a quality gun, so getting a great scope to match it should not be a choice – it should be a decision.

While these are the best Ruger AR 556 scopes on the market, we still suggest that you go through the tips in our buying guide before making your final pick. They are sure to guide you in narrowing down which scope is best for you.

For us, however, the…

…is our favorite scope. This unit provides you with several brightness settings and two illuminated reticles for a superior aim whenever you use it. Even in low light conditions, you’ll still be at the top of your game.

Also, with its all-weather compatibility and offering you a decent eye relief, you should see why this is our preferred choice. To cap these, you get a complimentary Vortex gift with your purchase.
