Osprey Scope Review

The Osprey scope is one of the best values in optical equipment. It offers excellent quality and performance at an affordable price. Its popularity among sportsmen is due to its versatility and durability. Available with both fixed and variable focus models, the Osprey is a good option for hunting.

Osprey Rifle Scope Durability

We found Osprey’s manual that contains details about how they test their scopes to see if they’re waterproof or not. According to the manual’s specifications, the scopes are water resistant when exposed to temperatures up to 40°C (104°F) for 3 min and fog proofed when exposed to temperatures down to -20°C (-4°F).

Some great scoping options are also waterproof, so you don’t need to be worried when your scope drops. This leads to good product durability.

Lens & Coating

It features fully multi-coated lenses with anti-reflection coatings, which help reduce reflections and offer excellent low-light performance. Likewise, it’s the reason why the camera is able to produce high-contrast images.

Regarding the optics, the manufacturer has been transparent that they’re using high-quality Hoya glass imported from China. The lens sizes and diameter also adhere to the industry standards of 40 to 44 millimeters for a medium rifle scope, but some models also have extensive, objecti­ve optics going up to 55 millimeters.


There are two main kinds of magnifiers: ones that adjust their magnification based on existing circumstances (such as when you’re looking at something close up) and ones that allow you to choose from a wide variety of settings for different situations.

For example, the Standard 2.0x 20mm Duplex Reticle has fixed magnification.

Some zoom lenses for cameras may go up to 24x magnification. So, if you’re using one of these, you might be able to get closer to your subject without losing focus.

There are several alternatives for magnifying glasses with promising magnification. For example, Nikon and Leupold are two popular choices.

Focal Point

If you’re using a scope with a fast-focusing eyepiece, just turn the focusing ring until the reticule appears clear and sharp. However, if the manufacturer doesn’t mention whether they include a locking ring, don’t assume they do.

There are two types of scopes: First focal planes (FFP) and second focal planes (SFP). FFPs are typically better for longer ranges than SFPs.

Mounting – Osprey Scopes

It’s important to make sure that the rifle has been properly zeroed before shooting.

One final note: If you’re not sure whether your scope is properly installed, check by looking at your scope through the bore of your rifle. You should be able to see the top of the scope mount when you look down the barrel.

If you can’t see the top of the mount, then your scope isn’t correctly attached to your firearm. Always consult or ask for help from a qualified gunsmith before proceeding any further.

Mass & Dimension

There are several Osprey scoping options available at different price points. Consider the lightest option if portability was ever an issue for you.

The company also claims to offer you a top-of-the-line compact rifle scope without compromising its functionality and quality.

Reticle Orientation

There are two main types of illumination systems: Single-colored (e.g., green) and multi-colored (red, green, and blue). Green is often used for bright ambient lighting, whereas reds are typically preferred for low-light situations. Some scopes have reticle markings engraved into their lenses.

However, the manufacturer recommends using the right settings for your particular camera lens. If you use an incorrect aperture value, you may experience halos and/or distortion.

Dust Protection

It’s important to protect your lenses by keeping them clean.

So, Osprey Optiks makes sure that all its products use a dust cover to keep dust out.

Some brands offer additional protection by including a powdery coating for extra defense against dirt and grime.

Osprey Global Tactical 6-24X50 Mil Dot Signature Series Scope

If you’re a short-range shooter, you may want to consider this tactical rifle scoped rifle as it has a 6x to 24× zoom range. It’s ideal for target shooting, hunting, and even for use at a shooting range.

According to our Osprey scope test, the company also designed Mil-Dot Reticle for determining the object distance when its size is already known. Furthermore, the three-level illumination at three intensities works well with the 50-millimeter objective lens in providing you with a clear image.

Osprey Global First Focal Plane 1-4×24 Scope

With its three different illuminated reticles, this rifle scope helps you quickly and accurately target objects at varying distances. Based on reviews and our research, this rifle scope helps keep you locked onto your target even when shooting at long ranges.

It may be easier to carry if it’s lighter than most scopes. However, the objective lens of the telescope is only 24mm, which means it’s not really suitable for observing objects.

Some people say that the optical performance of the Nikon D810 is similar to other Nikon models like Nikon Bucks­ter and Nikon Prostaff. They may be slightly expensive, but others say they’d pay double the price for this kind of high-end camera.

If you’re still thinking of yourself as an average shooter or hunter, you might think the rangefinder reticule of this scope could help enhance your abilities. The hash marks in its center can also be used as BDCs for long-range targets when you’re out in the field.

Osprey Global Standard 2.5×20 Duplex Reticle

If you bought one.22 rifle or shotgun, then you may wish to consider using this standard duplex reticule. Although designed for close shooting, this could also be useful in the medium range. Note, though, that some people consider its fixed magnification as a limitation.

According to our Osprey scopes reviews, you’d also see that it has the smallest aperture size among these three models. However, it still provides you with a clear and crisp image due to its light transmission power. It also offers excellent eye relief for comfortable viewing.

Osprey Global Standard 3-12×44 Mil-Dot Rifle Scope

It’s not too light, but it’s not too heavy either. It’s good for people who normally use firearms with a lot of recoils.

With a relatively wide 45-millimeter objective, Osprey assures its users of one sharp and clear picture, if they want one. And not to mention how the lighting would provide contrast between their reticle and target.

Are Osprey Scopes Worth It?

It has a multi-colored illumination system, good eye-relieve, and strong contrast imaging capabilities which reflect its excellent optical performance.
