{TOP 8} Best Prism Scopes Review And Guides 2021

If you don’t want your rifle weighed down by a traditional heavy riflescope but don’t want the limitations of a red dot sight, a prism scope may be the perfect solution. If you aren’t sure what a prism scope is or why you should use one, we’re here to help. We’re here to answer your questions and help you decide if a prism optic is right for you. We also have reviews of what we consider the best prism scopes on the market today.  

What is a Prism Scope? 

Unlike traditional riflescopes that use lenses to focus and magnify an image, prism scopes (also known as prismatic scopes) use a special glass prism. The design allows them to magnify images with a shorter, more compact design. The prism design also limits them to fixed magnification, usually somewhere between 1x and 5x. 

Why Use a Prism Scope? 

These relative newcomers to the optics scene are lighter and more compact than the traditional riflescope. They also offer a wide field of view (FOV). However, unlike the standard red dot, most models offer at least some modest magnification.  

The small size and lower magnification of prism scopes make them particularly well-suited for AR-15s and other tactical carbines. 

The main advantages of using a prism scope are: 

• The lightweight, compact design. 
• Large FOV. 
• Illuminated reticles for better visibility in all light conditions. 
• The reticle is usually etched in glass so you can see it even when your batteries fail.  
• Offers more sophisticated reticle designs than the standard red dot sight. 
• Prism sights work best for astigmatism. 
• A nice balance between rapid shooting for close-range targets and precision accuracy on targets at range.  

What to Consider When Buying a Prism Scope 

Prism scopes are great tools for hunting, three gun competition, and tactical applications. With a wide range of uses, it is impossible to list one perfect prism scope.  

Because not everyone needs the same performance from their rifle optic, the best option is the one that best fits your needs. That optic will look different for different shooters. 

Here are a few key features to consider when shopping for your own prism scope. 

Magnification  

Some prism scopes do not magnify the image at all. These 1x optics still provide all the aiming advantages associated with an illuminated reticle. They are useful for competitions that restrict magnification but still require rapid target acquisition for quick shooting.  

1x magnification is also useful for shotguns intended for home defense, especially since home invasions most commonly occur after dark.  

The illuminated reticle and superb light transmission typically associated with a quality prism scope will help you see both the reticle and the target clearly, even in low light. 

Other prism scopes offer image magnification between 1.5x and 5x. Although this level is lower than a standard rifle scope, it is still useful for accurate shooting at medium distances (usually out to 600 yards depending on the caliber you’re using).  

Reticle Design 

One advantage of using a prism scope over a red dot optic is that they offer a variety of reticle designs. Rather than a simple red dot, you can choose from horseshoe and circle dot reticles, simple crosshairs, and BDC (bullet drop compensator) reticles that are calibrated for specific cartridges. Some reticles can even help you estimate the distance to your target.  

For rapid, close range shooting, choose a reticle with a simple design. If you need to shoot unknown distances, a rapid ranging reticle could become your new best friend. If you expect to engage targets at distances beyond 100 yards, a BDC reticle (choose one designed for your specific load) can be particularly useful. 

Construction 

Most prism scopes are built to be extra durable. Because they are often used for hunting or tactical shooting, manufacturers know their products need to be tough.  

Look for a prism scope made from high-quality materials like 6061-T6 or aircraft quality aluminum. Also, look for optics that are o-ring sealed and purged with nitrogen or argon. This not only helps make the image clearer, it also prevents internal fogging due to humidity or rapid changes in temperature. 

You should also look at the coatings used on the prism and scope glass. Most contain layers of special coatings to help reduce glare, maximize light transmission, and produce crisp clear images with true-to-life colors. For the best image quality, look for a scope that features fully multi-coated optics. 

Battery Life 

Many prism scopes rely on batteries to power the optic’s illumination. Battery life varies by model. Those with higher brightness settings typically burn through batteries more quickly.  

Prism scopes with fiber optics don’t rely on battery power, so you never have to worry about changing batteries. 

Cost 

We’ve tried to include optics on our list to fit every price range. If you want the highest quality prism scope, be prepared to pay for it. Quality and performance don’t come cheap.  

However, if you don’t have a ton of money to drop on an optic, some of the more affordable scopes on our list are surprisingly capable. Just don’t expect them to have the features or clarity of a more expensive optic.
