What is a Prism Scope

Before we delve into the selection process, let’s first understand what prism scopes are and how they work.

Prism scopes are a type of optical sight that utilizes a prism to reflect and bend light, allowing shooters to acquire targets with precision and speed.

Unlike traditional scopes, prism scopes are compact and lightweight, making them ideal for tactical shooting and situations where mobility is crucial.

The prism inside a prism scope acts as a reticle, displaying the aiming point and providing the shooter with a clear and magnified view of the target. These scopes often come with fixed magnification settings, allowing shooters to positively ID targets at various distances.

Prism scopes are known for their ability to provide a crisp and bright image, even in low-light conditions, making them highly versatile for different shooting environments.

Key Factors to Consider

When selecting a prism scope, several key factors should be taken into consideration. Let’s explore each of these factors in detail to help you make an informed decision:

Optical Clarity and Quality

One of the most critical aspects of a prism scope is its optical clarity and quality. The quality of the glass used in the scope will greatly impact the clarity and brightness of the image you see through the scope. Look for scopes that use high-quality, multi-coated glass, as this will enhance light transmission and reduce glare.

Reticle Type and Illumination

The reticle plays a vital role in aiming and acquiring targets. Different prism scopes offer various reticle types, such as duplex, BDC (Bullet Drop Compensation), or illuminated reticles. Consider your shooting preferences and the type of shooting you engage in when choosing the reticle type. Additionally, opt for a scope with adjustable illumination settings, allowing you to adapt to different lighting conditions.


The magnification of a prism scope determines how much you can zoom in on your target. Consider the shooting distances you usually encounter and choose a scope with an appropriate magnification range. A wider range allows for more versatility in different shooting scenarios.

3x magnification seems to be the sweet spot for prism optics. Any more than 3x and you’re getting into LPVO territory. 2x Prism Optics are great for pistol caliber carbines, whereas 3x are best for most AR platforms.

Eye Relief and Field of View

Eye relief refers to the distance between your eye and the scope that provides a full field of view. It is crucial to select a prism scope with comfortable eye relief, especially if you wear glasses or participate in rapid target acquisition. Additionally, consider the field of view offered by the scope, as a wider field of view allows you to track moving targets more effectively.

Durability and Weather Resistance

Since tactical shooting often involves harsh environments and rugged conditions, it is essential to choose a prism scope that is durable and weather-resistant. Look for scopes constructed from high-quality materials, such as aircraft-grade aluminum, that can withstand recoil, impacts, and exposure to moisture. Additionally, consider scopes with nitrogen or argon purging to prevent fogging and ensure clarity even in extreme weather conditions.

Comparison of the Best Prism Scopes

Now that we have covered the key factors to consider, let’s compare some of the three best prism scopes available on the market.
