Features of the Firefield NVRS 3×42 Gen 1 Rifle Scope

Night vision scopes are typically quite costly, including Gen 1 options. However, you will find that the Firefield NVRS 3×42 Gen 1 is affordably priced, which is one of the reasons it is so popular. However, having a good price doesn’t mean that the device skimps on quality and features. The scope has high-quality technology and benefits that help to make it such a great choice.


Naturally, one of the first and most important things to consider when buying any type of rifle scope is the magnification and the quality of the optics it can offer. The same is true of night vision scopes. This scope has a fixed 3x zoom, which is in line with what you will find with most of the Gen 1 scopes. They are meant for close to mid-range shooting and they excel at ranges out to about 100 yards.

The objective lens diameter is 42 mm, which does a good job of gathering light. The lenses are multicoated, but they are not fully coated. The night vision scope comes with a flip-up front cover. This is nice for hunters who might be trekking through a rough environment and who want to make sure they can keep their scope’s lenses safe from getting scratched.

Users will also appreciate the red duplex reticle, which features adjustable brightness settings. This ensures you can adjust the brightness depending on the environment and the amount of light you have available. It is easy to ensure that the reticle is always easy to see. The scope can provide you with a clear picture of your targets thanks to the quality of the optics.

Night Vision Performance

Since this is a night vision scope, you will want to know how it can handle working in the dark, of course. The NVRS 3×42 night vision rifle scope features a built-in IR illuminator that can help to improve the details of images at range, even while increasing the range in total darkness.

You will find that the magnification and the IR capabilities of the scope will serve you very well out to about 100 yards. In good conditions, you might be able to stretch this out another 50 or so yards, but the ideal way to use the scope is within about 100 yards of the target. This can work quite well while you are hunting coyotes at night, for example.

The resolution on the scope is phenomenal for the price. It features 30 lines per mm and will help to provide a nice picture of targets when you are shooting from short to medium ranges. The illuminator ensures that even in darkness, you will be able to get good images.


The scope has a titanium body, and the weight is at around two pounds. While this might be considered light enough by many hunters who want to use it on their rifle, it could be on the heavy side for others. The scope is rugged enough to use on a hunt, but you will want to keep in mind that it is not waterproof. Instead, it is water-resistant with an IPX4 rating. This means it will be resistant to water that is splashed from any direction.

The overall construction of the scope is excellent. The knobs and the buttons on the scope are high-quality and are built to last a long time. It’s easy to turn the IR on and off, and it is easy to change the brightness of the reticles all with one hand. The battery life for the scope is quite good, as well, whether you are using the IR or not.

Mounting the Scope

Getting the night vision scope mounted is fast and simple thanks to the quick-detach weaver mounting system. You can change out your optics quickly, or simply remove the scope and use the iron sights on your rifle. It boasts that it will still provide return-to-zero reliability.

While the mounting system is great in theory, some people have had issues with it. They have found that once the scope is attached, the base can start to get loose, which could cause the scope to fall from the rifle. That is not something that any hunter wants. Rifles that have a substantial amount of recoil could cause problems, as well.

This tends to be a minor quibble that does not affect all owners, but it is worth pointing out before you make a purchase decision. It’s possible to make adjustments, so you don’t have this issue with the scope if it becomes a problem. 

What Comes with the Scope?

When you choose the NVRS 3×42 night vision rifle scope, you will not be getting much in the way of accessories. It does include a cleaning cloth and a carrying case, which are nice to have. It also has the user’s manual, of course. It comes with a warranty, as well, to give you some additional peace of mind.

Why Choose a Gen 1 NV Scope?

With other generations of night vision scopes on the market, you might be wondering why you would want to consider using a Gen 1 model. Even though they might be an older model, they are still useful and can provide you with excellent results, often at a better price than the newer options on the market.

The different generations of night vision technology have differences in their capabilities. Gen 1 is the most popular option and is typically used by civilians who are hunters and who need to see prey like coyotes in the darkness. Gen 2 is commonly used by law enforcement and provides better imaging, better battery life, and better low light performance. Gen 3 is used by the military in most cases, and it improves the range, image quality, battery performance, and more.

For hunters, Gen 1 will do the job nicely. Given all of the features that the Firefield NVRS 3×42 Gen 1 can offer, it’s easy to see why this is still a popular choice. It performs well, is easy to use, and could make a good addition to your hunting gear. 

What You Need to Know About Buying Night Vision Scopes

Although they might look like a regular scope, night vision scopes tend to have a lot of technology included in their housing. It’s this technology, such as the IR illuminator, which allows them to operate and provide you with a target even in the dark.

Illumination should be considered, as well. A Gen 1 scope will need to have some type of illumination, even if it’s a small amount, to work properly. One of the benefits of choosing a scope like the Firefield NVRS 3×42 is that it has a built-in IR illuminator. Although using it might take up more of the battery power, it means that you will be able to hunt and shoot in darkness.

When choosing a night vision scope, you will also need to think about the magnification it can offer. Although some might be able to go up to 10x, you will find that 3x and 5x scopes are more common, and they tend to be more practical. Most hunters are not going to be shooting at longer ranges in the dark. Lower magnifications are also more affordable.

You should also look at the field of view when buying a scope, whether it is night vision or not. The field of view for the Firefield NVRS 3×42 is 21′ is 100 m. While it might not be a massive FOV, it should still provide you with enough room to find and get on your target. 

Naturally, the quality of the image is important when choosing your NV scope. Always look to see whether the optics can provide you with a clear image before buying. This is essential if you want to be able to take accurate shots. The lines per millimeter rating, which is 30 on the Firefield NVRS 3×42, will let you know how clear your sight picture will be.

Naturally, you will also want to think about the durability of the scope, along with the weight and the size. It needs to be able to fit properly on your rifle, and you will want to be sure it won’t add too much weight to your gear.
