What distinguishes LPVO (Low Power Variable Optics) from a Prism Scope?

The prism scope features a single prism lens, in contrast to the multiple lenses found in traditional optics. This design allows for a significantly shorter build. The length is reduced by half or even more compared to a traditional LPVO, while still retaining a reticle.

This offers a significant advantage, especially with the larger two models (Paragon 3×18 and Paragon 4×24), as they facilitate precise shooting even at extended ranges.

What are the primary distinctions between a red dot sight and a prism scope?

First and foremost, the prism scope features an adjustable eyepiece. This allows for precise focus on the reticle, which is especially beneficial for individuals with astigmatism. Those with astigmatism often experience blurriness when viewing red dots, resulting in a less-than-optimal experience with reflex red dot sights. However, with a prism scope, they can effortlessly focus on the reticle and utilize it with ease.

The second advantage of the prism scope is that even if the battery dies, you still have a reticle to rely on. In contrast, with a traditional red dot sight, you lose your point of aim entirely. This makes the prism scope a more reliable option for aiming in various situations.

Prism scopes are also significantly larger compared to red dot sights.

Physical Properties of Paragon Prism Scopes

As previously stated, the Paragon prism scopes have an incredibly compact design. They are entirely crafted from aluminium, with no rubberized components present on the optic, except for the buttons dedicated to illumination control.

All three models undergo nitrogen purging, rendering them fully sealed and boasting an IP67 waterproof rating. This signifies their ability to withstand depths of up to one meter for a minimum of 30 minutes.

Additionally, they exhibit shockproof capabilities, accommodating even the recoil of a .300 Winchester. As such, they are ideally suited for use with a .308 Winchester and can be employed throughout the entire day.

The height of the Paragon prism scopes varies from 60 to 65 millimeters. The Paragon 1×16 model measures 75 millimeters in length and weighs a mere 225 grams, making it incredibly lightweight. Similarly, the Paragon 3×18 model also weighs 225 grams, but it is slightly longer at 77 millimeters. The largest model, the Paragon 4×24, is not only the longest at 84 millimeters but also the heaviest at 255 grams.

Adjustable Eyepiece

Paragon prism scopes are equipped with an adjustable eyepiece that allows for precise focusing on the reticle.


The reticle is integrated into the lens across all three models. In the smallest model, the central dot measures 2 MOA in diameter, complemented by a 68 MOA circle surrounding it.

Both of the larger models share the same reticle, equipped with a 1 MOA dot at the center and a 21 MOA circle around it. The reticle on these two models also include a BDC line, complete with markings for distances of up to 600 yards. This is particularly useful if you are using standard .308 Winchester or .223 Remington ammunition.

Each model is equipped with only one reticle.

Illumination System

The illumination is exceptionally bright, making it suitable for use even on the sunniest of days. In total, there are 10 intensity settings, with the initial ones specifically designed for night vision use. The first intensity setting is perfectly compatible with night vision devices.

The illumination of the Paragon prism scope can be easily adjusted using the plus and minus buttons, enabling you to fine-tune the intensity to your liking.

The illumination of the prism scope is powered by a single CR 2032 battery, conveniently positioned on its side. This design ensures optimal functionality and ease of use.

Low-profile Turrets

The turrets on all three Paragon models share an identical design. They feature an open and straightforward structure with a direct axis. However, it is important to note that they may not be suitable for use in sandy or muddy conditions due to their lack of protection, which makes them vulnerable to debris ingress. However, adjusting the turrets is effortless, whether it’s done using a screwdriver or the provided tool.

The standout feature of this turret is its remarkably low profile. Unlike traditional optics where the cap protrudes, Paragon prism scope offers a sleek and compact design, ensuring a minimal profile.

The clicks of the turrets feel and sound precise, allowing you to easily perceive each click on the optic. The windage and elevation adjustment range is an impressive 40 MOA, providing ample flexibility. The turrets feature a multi-turn design but lack any markings. However, for optics of this nature, it is perfectly acceptable.

The turrets lack a turn indicator and a zero stop, and they are also notably stiff. Therefore, there is no need to worry about accidentally adjusting the turret.

Where can I identify areas for enhancement? Apart from the turret caps, I have no further remarks to make. Perhaps the turrets could be safeguarded with caps to prevent the ingress of mud or sand into the small openings. However, apart from this consideration, I believe there is little room for improvement from my perspective.

Cons Summary:

1.      Turrets without caps
