The scope is lightweight but has been proven to survive Punisher, Leupold’s very own recoil simulation machine which means that it is built to survive a minimum of 5,000 impacts with each impact powered with a force 3x the recoil of a .308 rifle.

  • Shockproof, fog proof, and waterproof
  • DiamondCoat 2 coating
  • Made with 6061-T6 aircraft grade aluminum
  • Turret design

Another unique feature is the reticle is etched on the glass thus can provide additional support when it comes to recoil resistance. The reticle is also illuminated.

  • Reticle Illumination
  • Fully multi-coated lens and XPL lenses
  • Shockproof and waterproof
  • Etched glass reticle
  • 6061 T6 Aluminum built
  • Adjustments are not that user friendly

Includes flip open objective and Eyepiece covers

The weather is beyond anyone’s control so to help protect your rifle scopes, Bushnell improved the RAINGUARD HD and developed the new EXO Barrier.

This results to an ultra-slick coating capable of repelling fog, oil, dust, debris and most importantly, water. Snow, rain, fingerprints are a complete no-no and won’t stick at all.

At below $400, this scope comes with eye piece covers and a flip open objective for protection. This is packed with a hunter’s dream.

However, it would make it even better is if it can provide reticle options and not just the Deploy MOA.

  • Tool-less zero reset
  • Locking turrets
  • Exclusive EXO Barrier Shield
  • Waterproof and fog proof
  • Fully Multi Coated
  • The lack of reticle options

This still gets a thumbs up because if you are the type of shooter that will settle for a fine MIA reticle hash mark then you’re basically good to go. It is affordable, it works as expected and even goes beyond expectation so this is surely a great deal.

You get all this for a price point of less than $400. You also get a scope that can hold zero on even the heaviest recoil. It also has heightened magnification so targets of farther distance can be locked in with ease.

Just a little disadvantage is it is on the bigger side when compared to other scopes in the market. Since it is quite large, it weighs a little more too.

  • Illuminated reticle
  • Simple adjustments
  • Comes with a sun shade
  • Enhanced magnification
  • Built to last

Still, even if it is bigger and heavier, it is still a great buy and worth every penny. It is a nice scope and is very promising when used in your next hunting expedition.

What to Expect from the Rifle Scope Under $400

Currently, there are a lot of quality scopes on the market that can provide impressive results. Established scope manufacturers known to be experts in producing high quality scopes usually becomes successful because they can find the perfect balance to entice the shoppers into buying.

With a budget that is decent, you must be willing to compromise and settle for not really having the best of the best features but a scope that is mid to high end and will still improve your visuals in locking targets.

For a scope with a price limit of 400 dollars, you can expect at the very least that the lens is multi-coated and that the material used is high grade aluminum alloy for durability and longevity. Surely though, scopes that fall under this budget limit can already provide you with accuracy, precision, and stability and are commonly compatible to most hinting rifles in the market.

Scopes within the 400 dollars budget can also be expected to have some features related to magnification but of course, the quality of the image upon zooming in and out will really be dependent on the model and brand.

Rifle scopes within this price range are also designed to be waterproof and fog proof with some the extra feature of being shock proof. But these scopes can handle the elements of nature and the human abuse and frequent use. These budget friendly scopes are also easy to set up and requires very minimal to zero maintenance.

Although very limited, you might also find scopes with added laser sight or pointer, one with a reliable long-distance focus, and anti-reflective coating. Also, some will come with additional features and add-ons like a red dot sight, a duplex reticle or a mil-dot reticle, lens caps or even better customer service coming from the manufacturer that can be contacted for a layer of security and peace of mind.

How to Choose the Best Rifle Scope Under $400

Choosing the best rifle scope under 400 dollars is quite a challenge but a feasible one. Will you end up getting one that can up your game and help you lock in those targets? Yes. But you must set some guidelines so you can end up choosing a good one and still within your price range. Here are some of the factors that you must consider:


You must know exactly what kind of shooting are you normally involved in. If you are into mid-range shooting, you must specifically look for scope options that is compatible with mid-range shooting. For long-distance shooting, you will entirely need a different scope with additional features for that. Mid-range shooters will prioritize speed and movement while long-range shooters will make sure that their precision is 100% and their magnification scope is very high. Know your preferred range.

Precision Power

Regardless if you are shooting mid or long-range, you must choose a scope that can give you optimum precision. This should complement your skill so you can enhance your overall locking target efficiency. The precision power will be a combination of your magnification and the clarity of your lens.


Choose a scope that is made with aluminum alloy. You’d want a scope that will last for a good number of years so opt for one that is built with high quality and guaranteed durable. A tube construction made of aluminum alloy last longer. Scopes made of steel should be found at the very bottom of your list.


This is where a little compromise happens on your part as a buyer. You must ensure that your focus is on the zooming in and out and that if your options allow you magnification, the image’s quality is still acceptable. You also must choose a scope where the transitions of view are smooth because if the zoom in and out is not even, you will lose the accuracy of your shot and target acquisition will be very unstable.

Objective Lens

One of the most critical factors you must consider since this is where the clarity of your image comes from. Regardless of light conditions, a bigger lens is always the smart choice because the bigger it is, more light can come in and when there is light, the image clarity gets better. Always choose a scope with a bigger objective lens but as a word of precaution, the bigger your lens are, the heavier it is as well.


Where are you going to mount your scope? Will it be a good match and will complement each other? This might be a common miss when shopping but consider your existing rifle or weapon. During your hunting trip, your weapon and scope should be able to work as one when it comes to locking in the target accurately and making that shot. Also, your choice of scope should also be strong enough to withstand the frequent recoil from your weapon. Its battery life should also be long enough to continue working with you and your rifle.

Lens coating

You only must choose one for this and it should be multi-coated at the very least. This helps with the sight picture of your target. Usually it also comes with anti-glaring features so regardless of the light conditions and intensities, you retain a consistent view of your target. You can also consider the brightness settings that the scope can offer.

(Source: [1])


A budget of $400 coupled with the right information can land you with a hunting rifle scope that can suit your needs and even tick off some features off your wish list. You don’t have to settle for anything less if you feel like the scope can’t cater to your basic expectations. Finding the best rifle scope under $400 is doable and it is a reasonable budget too in the first place.

However, if your requirements and expectations are a little steep and more extreme like having an unobstructed vision of the target or perhaps intense magnification, then it would be best to loosen your purse strings and be willing to add in in a few more hundreds on your budget.
