5 Tips on How to Protect Your Hunting Rifle Scope From the Elements

Just bought a hunting rifle scope and wonder how to protect it when you go on your outdoor adventures? Not sure how to do it or if you need to buy extra equipment?

Hunting isn’t a hobby you can do sitting at home where you’re protected from the elements. It’s a rugged activity where you and your equipment will be exposed to everything mother nature can throw at you.

From things like the rain, heat, or cold to accidents like dropping your rifle and scratching the lenses, there are many ways hunting rifle scopes can get damaged while you’re outside.

Fortunately, there are many ways you can protect and weather-proof your hunting rifle scope without spending a fortune or having to worry about it constantly. In this guide, we’ll teach you how to do it yourself.

Buy a Scope Lens Cover or Dust Cap

The most effective way to prevent your scope lenses from getting damaged is by getting a scope lens cover (sometimes called a dust cap) for both ends of the scope.

There are an unbelievable number of lens covers that you can find that will fit any size rifle scope. In fact, many rifle scope companies sell it alongside the scope.

If your scope doesn’t come with one, you can get a pair that screws on and off, pops on and off, or flips up and away from the scope’s front and rear, allowing you to push the flaps down when you’re done.

While this part is up to personal preference, the flip-up lens covers are the most convenient — no need to worry about where to store them after use.

Get a Full-Size Scope Cover

Other than the lenses, the scope’s body also needs protection. The best ones are made of a neoprene material that protects the metal parts of the scope from corrosion and scratches.

The neoprene material is usually thick enough to absorb most normal bumps and knocks it can encounter during regular use. These covers also conform tightly to the scope’s housing, providing no extra bulk.

Even if dirt does get stuck between the neoprene cover and the scope, the material’s soft nature means it won’t scratch or damage your scope.

Don’t Store the Scope Outdoors

When you’re done using your hunting rifle and scope, make sure not to leave them exposed to the elements by storing them outdoors.

Factors like humidity, temperature, water, and oxidation will damage your scope over time, especially if you live in a more humid area or near the sea.

The safest thing to do with your hunting rifle scope is to store it indoors, where it won’t be exposed to harsh conditions.

You might also want to consider getting a storage case or bag for your scope and rifle, whether you always take your scope off or keep it on your rifle after use.

Use a Sling With Your Hunting Rifle

Using a sling with a hunting rifle is highly recommended for safety and convenience reasons. It keeps your hands free if you need to do other things like grip on trees for stability or dig the bullet out of your prey’s carcass.

However, using a hunting rifle sling can also prevent damage to your scope. If you accidentally drop the rifle while holding it, the sling prevents it from hitting the ground.

Using a sling with a hunting rifle is highly recommended for safety and convenience reasons.

Imagine if you didn’t have a sling. The rifle would hit the ground hard, most likely damaging the sensitive scope, which would be a very costly mistake.

The sling allows you to be more mobile and walk freely without the rifle getting in your way while keeping it close to the body. This reduces the chances of it bumping into trees.

Clean Your Hunting Rifle Scope After Each Use

One step that can keep your hunting rifle scope looking brand new for years to come is regular cleaning. This is because your scope will be splattered with dirt, dust, moisture, and other external elements.

If you clean your scope each time after hunting and before storing it indoors (and in the case), you’ll prevent any dirt, dust, or particles from sticking to the scope.

You’ll want to remove any excess dirt particles because some are abrasive enough to scratch the material of your rifle scope, even if it’s marketed as scratch-resistant.

Just because your rifle scope is rated to be weather-resistant and scratch-resistant doesn’t mean you can be careless with it. It just means there’s a less likely chance it will get damaged if you are.

How You Can Protect the Rest of Your Rifle

While protecting your hunting rifle scope, you should also take care of the rifle it’s mounted on. Some of these tips and tricks can be done simultaneously to protect both the optic AND the weapon.

Put Muzzle Tape on Your Barrel

Your rifle’s barrel is one of the largest entry points where dirt, dust, and humidity enter. It’s also the part of the rifle most crucial to accuracy.

Having any rust or corrosion inside the barrel isn’t ideal and can lead to irreparable damage. Taping the front end of the barrel with electrical tape can help cover it up.

After shooting, the electrical tape will come off by itself. Then, Remove the extra pieces with your hands (unload the weapon first, of course).

Before you clean the gun and put it back into storage, you can put more muzzle tape again so that you don’t forget it the next time you go hunting.

Use Protective Anti-rust Coatings

Using anti-rust coatings on the outside of the rifle can help keep it rust and corrosion free. Make sure to apply these anti-rust or corrosive solvents on the outer part of your rifle.

Examples of anti-rust coatings are Rem Oil, WD-40, Kroil, and Corrosion-X. You can apply these by putting the liquids on a damp cloth and then rubbing it on your barrel’s exterior.

Disassemble and Clean After Use

You should disassemble and clean the parts of your rifle, especially after a particularly dusty, humid, or wet day in the field. You can do this as part of your end-of-day routine.

Disassembling and cleaning the rifle of all oils and grime helps, especially in icy or dirty conditions. For icy conditions, cleaning up the oil prevents it from freezing and getting too sticky.

For dirty and dusty conditions, the oil might mix with dirt and dry up as the day progresses, causing it to turn into a thick mush that will clog up your rifle.

If you’re hunting in frigid weather, consider disassembling it and leaving it in a cold but covered area. Putting it back in average temperatures might induce condensation.

Frequently Asked Questions

After learning more about how to protect your hunting rifle scope from the elements, you might have some related questions. Here are answers to the most commonly asked ones.

Can You Wrap a Scope?

You can choose to wrap your scope in vinyl skin as an additional layer of protection while you’re out and about instead of using a neoprene cover.

Most people buy it because you can choose custom designs or add camouflage to a plain-looking scope. Functionally, it can also repel some dirt and prevent rusting.

However, remember that it shouldn’t be used as a replacement for a full-size neoprene scope cover. This is because it won’t protect against any bumps or falls.

Can a Rifle Scope Go Bad?

Sometimes, the rifle scope will go bad (losing accuracy, clarity, or reliability) even if you take care of it properly. In this case, take some time to diagnose the problem before going hunting again.

If the rifle has just lost its zero, then all you need to do is zero it in again. However, if it constantly loses zero right after adjusting it, there might be another issue.

If you see fogging or liquids inside the scope, it means that the waterproofing seal has broken, and you won’t be able to trust the scope for any accurate shots.

If it makes weird sounds whenever you move it, like something is loose inside, then you’ll have to replace the scope. Check with your scope’s manufacturer for warranty claims.

Can a Rifle Scope Lose Zero?

If you miss even when your shot should be on target, the most likely cause is that your rifle scope has lost its zero. There are many reasons why a rifle scope loses zero.

Sometimes, it loses zero because of excessive recoil, improper installation, incorrect scope mounts, or because you’ve dropped the scope hard.

Some of these issues require reinstallation or even bringing it in for repairs, but you can try to zero in the rifle scope again to see if it still works well.

Final Thoughts

Protecting your hunting rifle scope from the elements isn’t as complicated as it sounds. Methods like buying covers for the scope and lenses help prevent damage in most cases.

However, the most crucial way to keep your rifle scope (and the hunting rifle itself) clean and working 100% is to clean it after every use. It might take up a bit more time out of your day, but 2-3 years down the road, your optic will look almost as fresh as the day you bought it.

How Long Do Magazine Springs Really Last?

As a gun owner, you’ve probably assessed your firearm and examined where its reliability could be tested given a slew of survival scenarios. Undoubtedly, you’ve looked carefully at the magazine. It is after all the critical component that a magazine-fed firearm relies on to feed ammo into the chamber effectively and efficiently. Are you positive it’ll always work when you need it to? As you most likely know, a magazine contains a certain metal component which renders the entire firearm ineffective when it breaks or loses its elasticity. We are speaking of course about the spring, which is why the latest project from AmmunitionToGo.com recently garnered our attention.

How long can a mag spring last? Does leaving a mag loaded for an extended period of time gradually damage its spring? Does the simple act of loading a mag damage its spring in any measurable way? These are the questions Ammo To Go set out to answer by conducting a mag spring torture test (or mag spring enhanced interrogation test, if any congressional committees ask about it).

Ammo To Go’s Mag Spring Test Process

The team at Ammo To Go spent almost a year loading, unloading, and testing the spring functionality of 13 different mags:

  • Magpul Gen 2 PMAG (30 rds)
  • Magpul Gen 3 PMAG (30 rds)
  • Magpul Gen 3 PMAG (40 rds)
  • Amend2 AR-15 mag (30 rds)
  • Lancer AR-15 mag (30 rds)
  • USGI AR-15 mag (30 rds)
  • Smith & Wesson Shield 9mm mag (8 rds)
  • ETS Glock 17 mag (17 rds)
  • Glock 17 Factory mag (17 rds)
  • Magpul Glock 17 mag (17 rds)
  • Glock 17 Factory mag (33 rds)
  • USGI 45 ACP 1911 mag (7 rds)
  • Wilson Combat 45 ACP 1911 mag (8 rds)

First, they used a digital force gauge to establish each mag spring’s resistance. Then they subjected samples of each mag listed above to the following test protocol over the course of year.

  1. Load to full capacity; store in climate controlled environment
  2. Load to full capacity; store in shed where temperatures regularly fluctuate to over 100 °F
  3. Do not load; store in climate controlled environment
  4. Do not load; store in the miserably hot and stuffy shed
  5. Load to half capacity; store in climate controlled environment
  6. Load and unload to full capacity five times biweekly; store in climate controlled environment
  7. Load and unload to full capacity 15 times biweekly; store in climate controlled environment
  8. Load and unload to full capacity 15 times biweekly; store in the same horrible shed

The ATG crew regularly took the mags to the range for field testing throughout the duration of the test. Their team fired one round every two seconds, and then used the same digital force gauge to determine whether the mag springs’ resistance values changed in any significant way.

The Mag Spring Torture Test Results

After about ten months, hundreds of hours, thousands of rounds, and countless mosquito bites, their team determined the following: zilch.

Allow us to elaborate using the PMAGs as an example. Regardless of how frequently they were loaded or unloaded – and regardless of their storage conditions – not a single PMAG failed. The digital force gauge revealed zero significant variability in their springs’ resistance!

This isn’t to suggest that the PMAGs weren’t changed over the course of testing. In many cases the springs put up 20-25% less resistance than they had when the mags were fresh out of their factory packaging. Even so, all of the PMAGs performed flawlessly during field testing, and the other manufacturers’ mags followed suit.

So, They Did Even More Testing

The test protocol revealed that factory mags are pretty much unaffected by regular usage. But they wanted to determine precisely how much punishment a mag can tolerate before its spring starts pushing up daisies. That’s why they recruited help from the only people who are bigger nerds than us: the laboratory technicians of Applied Technical Services.

The team gave ATS a factory 17-round G17 mag and a 30-round PMAG. They slightly modified each mag to fit correctly into their spring compressing contraption and proceeded to punish the absolute bejeezus out of the poor little springs.

Their results were fascinating. The G17 mag spring endured 14,842 cycles (the equivalent of 252,314 rounds) before it snapped; the PMAG endured 69,881 cycles (2,096,430 rounds) before it finally gave up the ghost. To put that into context, if you were to fire a case of 223 Rem ammo every two weeks, the PMAG spring would endure for eight decades. That’s bananas!

Test Limitations

You can’t pretend that ATS’s testing perfectly emulated real world conditions. When they’re used by actual firearm enthusiasts, mags get dirty, subjected to temperature fluctuations, dropped, quickly reloaded, and otherwise mistreated. You can reasonably expect environmental damage to shorten a mag spring’s lifespan, but their tests didn’t confirm that expectation through scientific experimentation.

Regardless, it’s safe to conclude that mag springs are outstandingly rugged. Kudos to the manufacturers for appreciating just how essential springs really are!

Does Storing a Mag Half Loaded Extend Its Lifespan?

Many folks believe they can protect their mag springs by “downloading” – i.e. loading their mags shy of full capacity. Their reasoning is simple enough: by avoiding full compression, the spring retains its resistance and full functionality.

The ATG team put this theory to the test by downloading Gen 2 and Gen 3 PMAGs, as well as Amend2 AR, G17 and S&W Shield mags. After 10 months of identical use and storage conditions, they measured no significant difference in spring resistance between the downloaded mags and analogous mags that they left unloaded or fully loaded when they weren’t in use. Like we pointed out earlier, the test’s protocol doesn’t perfectly emulate real world conditions, but there’s no evidence downloading poses any actual advantage.

Conclusion

At the end of the day, it’s typically wear and tear or factory defects that render mags ineffective – not gradual spring deterioration. So long as you take care to maintain your firearm, you can expect reliable performance from your mag for many decades. One less thing to worry about, we say!
