Well, no. There is no difference. Both of them are the same thing just different expressions.

Are spring loaded flip-up caps any good?

Spring-loaded flip caps are some of the most durable out there. The spring is sharp and crisp. You won’t hear any spring crunching sound from it. On top of that, it makes the flip-up mechanism much smoother and lighter. If you are doing it with a clip instead, there will be added weight that you don’t need.

3. Butler Creek Flip-Open Eyepiece Scope Cover

Will this melt in high temperatures?

That’s a solid question for a change. I don’t think so. The maximum temperature it is rated for is 120F. That’s around 49 degrees in Celsius. Even in deserts, it should survive just fine.

4. Leupold Alumina Flip Back Lens Cover

Leupold means class. Even their flip-up covers glow from class. This is a universal flip-up cover that supports the scope made after 2003.

Is it a set? For both ends of the scope?

Unfortunately, no. This is only for the eyepiece of your scope. You will need a different one for your objective lens.

Does it work with rotating eyepiece?

Yes, this is the first Nightforce eyepiece flip-up cap that supports a rotating eyepiece. All of their previous editions used to interfere with rotating eyepiece Not this one.

7. Zeiss Victory V8/HT Flip-Up Objective Lens Cover

If you are into guns and stuff, you have heard of Zeiss. At least once. It’s one of the most expensive sports optic makers in the world. Their scopes are as good as a scope can get. And as expensive a scope can get. To make their expensive scopes more expensive, Zeiss released an objective lens flip-up cover.

What’s so special about it?

Honestly, it’s made by Zeiss. That’s enough for the mass. On top of that, it’s made from the same type of aluminum Zeiss use to make their scopes.

Will it fit the V4 as well?

While this cap is not marketed for the V4, it will support the V4 models with a 50mm objective lens. It may as well support other scopes with a 50mm objective lens. But don’t quote me on that, you might fail in your expenditure. It will be an expensive failure.

Will it fit Conquest HD5 3-15 x 50?

No, it won’t fit that due to two reasons. 1 it’s not officially supported. 2 that’s a 56mm objective lens, not 50. For that, you need to buy the cap set with a 56mm objective lens.


One thing to keep in mind from this is, that scope lens covers and flip-up caps are the same thing. These are marketing terms targeting different consumers. No matter which cap covers you take from here, it will protect your lenses from the worst.

Just keep in mind to buy the right version. You might not want to end up with a 60mm one when your scope is 30mm.
