Best Prism Scope for Your Survival Rifle: Top Picks

My tactical rifle is used to hit moving targets. I’m not worried about grouping a quarter-inch at 100 yards. I want a one-shot kill. And I want it almost reflexively.

best prism scope for your survival rifle

That means I’m avoiding a traditional scope. But I don’t want the limitations of a red dot sight either. Thankfully, we now have the best of both worlds. The solution is using the best prism scope on your rifle. They’re lighter and have a much better field of view (FOV) than the traditional scope.

The drawback is the limitation of their range. Even at 5x magnification, they aren’t going to be much help beyond 500 yards, which is plenty for me. I don’t plan on using my AR-15 as a sniper rifle. It’s for close quarters.

I’ll show you what you need to know so you can make your own choice about what prism scope is right for you.

4. Best System Integration – Burris T.M.P.R. 5X32 Survival Rifle Prism Scope Review

Burris 300238 T.M.P.R.-Fastfire M3 with Mount, 3 MOA Dot, Black

Take advantage of the versatile T.M.P.R. (Tri-Modular Prism Riflescope) system for confidence at any range up to 600 yards.

The laser and the reflex dot sights mount to the base unit to keep things compact. In fact, the centerline of the sight is at 1.53″ above the rail. On top of that, they added a dual throw quick-release Picatinny/Weaver rail mount to make installation easy and repeatable.

There are seven illumination levels for the three colors – blue, red, or green, to provide you with targeting options. There are also three night vision compatible settings. The T.M.P.R. System ensures a quick response with a field of view greater than the AR-332 or AR-536.

What You Need to Know About Prism Scopes

Prisms – Basically, a prism is a glass or other transparent object the shape of a triangle with surfaces at acute angles to each other. Light is bounced off of the surface so that white light is separated into a spectrum of colors.

What Is a Prism Scope and how does it work?

Actually, considered to be a type of red dot sight, prism scopes are more like a traditional scope that magnifies and focuses light. What makes a prism scope different is how the light is handled.

Chances are you have binoculars that use a prism system. They’re the compact, straight-line type. That advantage comes from how light is focused by a prism system. Basically, light is reflected off a prism instead of having to go through a series of glass lenses. Prisms are smaller size and the weight is dramatically reduced.

Prism scopes have an advantage because they usually have an etched and illuminated reticle. That makes the prism systems ideal for tactical rifles such as AR-15s. ​

Key advantages of a prism scope over a red dot sight:

  • The effective range increases because of greater magnification and a larger sight picture.
  • No fear of having your batteries drained causing you to lose your reticle (“crosshairs”). The black outline of the etched reticle remains. Although this becomes more difficult in low light situations like dawn and dusk.
  • Quicker target acquisition times are possible thanks to a sharper, brighter image.
  • Astigmatism and other eye conditions aren’t a problem when the prism scope has an adjustable ocular ring (also known as a diopter or fast-focus eyepiece).
  • The etched reticle on some models will provide the user with vital data such as target range estimation and bullet drop compensation holdovers.

Disadvantages of a prism scope versus a red dot sight:

  • The shorter eye relief (the distance you must hold your eye from the rear of the scope) is problematic if you’re wearing glasses.

Prism Scope Buying Guide: What To Look For

Durability

A bugout situation is not like a day at the range. Dirt, water, bumps, and drops are going to happen. Your equipment needs to withstand as much punishment as possible.

Scopes with multi-coated reticles will help ensure you have chosen a quality product. That extra coating also gives you a brighter image. Look for anodized aluminum bodies. Look that the scope is anodized aluminum. Anodizing will limit damage from scratches. Finally, check that  nitrogen-purging is used so you have dust, shock, and fog protection.

Mounting Options

You should easily find a scope with universal mounting. You likely already know if you have KeyMod, M-LOK, Picatinny, or another type of rail. Most rifles will have the Picatinny rails which almost all prism scopes will fit.

Reticle Advantages

I suggest you choose a scope with reticles that are etched and illuminated. Make sure you have brightness settings. Most have five while others give you up to 11. I personally find that five are plenty.

Some scopes give you the option to switch your (red and green usually) illuminated reticle colors. That should be your smallest option. Others offer a choice between seeing a dot or a cross.

Always look for reticles that are etched and provide illumination. This will increase your accuracy and improve the value of the prism scope. The scopes below have both.

Look for BDC (Bullet Drop Compensation) markings, especially for 5X scopes. You’ll find them standard for any decent quality scope.

Magnification

On Prism scopes, the magnification is fixed. Your choices are usually from 1X up to 5X with a few scopes that reach 6X. What level of magnification you choose here depends on how far out you have to shoot. Most people go with 3X so you can be confident out to about 300 yards.

Diopter Adjustment

People with astigmatism switch from traditional Red Dot sights to 1X prism scopes so they can have this feature.

Lenses

Here’s where the cost of any scope, binocular, or telescope is greatly affected. It’s also the feature that has one of the greatest impacts on your satisfaction. Your choice starts with coated or non-coated lenses, with colors. Always choose multi-coated. You can’t afford to skip here unless the scope is for a play rifle.

The next part of the lenses to pay attention to is the diameter of the objective lens. Look for lenses no less than 30mm. As the power of your scope increases, so should the size of the objective because that is what determines how much light gets in. I suggest nothing less than a 36mm lens for a 5X scope.


Verdict

Overall, any of the above prism scopes will be a great fit for a variety of users or situations. The compact size, great features, and lower price points make prism scopes an attractive option for a variety of survival rifles. And since they all come with mounts, they’ll also be easy to start using right away.
