Firefield 3X42 NVRS

You're going to have a hard time finding decent Gen 1 NV rifle scopes under $500 brand new, out-of-the-box anywhere.  Fortunately for you, Firefield brings NV technology right to your doorstep with prices that literally can't be matched.  One such Gen 1 scope is the NVRS 3x42.

It has a durable titanium body and a light weight of almost 2 lbs, although, this weight might be heavy for some hunters.  This NV unit has a convenience feature, the quick detach weaver mount.  This allows you to remove and remount your NVRS scope at a moment’s notice if you wanted to switch back to iron sights.

Don't want to sight in at night?  Sighting in at dusk is the best way to go with the supplied peephole through the lens cap of the scope.  Make your adjustments and voila - you shouldn't have to pop off unnecessary ammo.  A few rounds should do it especially since the scope holds its zero and can withstand recoil up to a .308 and AR10.

But, you want to know how far out it can see, right?  While this question is a boon to many manufacturers, we will tell you that this NVRS scope will be good out to 75-100 yards with the 805 nm IR activated in open areas.  In short range areas surrounded with bushes and trees of sorts, detection range may only be 30 yards due to the washing-out effect of nearby objects.  In the thick timber, you mightn't be able to see anything at all, so evaluate your hunting terrain and style before considering the scope.

However, even the scope's IR limitations can't be stopped here.  You can add your own long-range IR to your rifle to extend that detection range.  This solution seemed to be good enough for many buyers.  Its durability and well-built construction was noticed and appreciated.  However, sighting-in seemed to be an issue for some users, and black dots within the inside of the lenses were problematic enough to be distracting and warrant a return.

Firefield NVRS 3X42 Q&A:

What does NVRS Stand For? 

NVRS - Night Vision Rifle Scope.

Is the Firefield Night Vision Scope Waterproof or Water-resistant? 

The scope is rated at IPX4 which is generally accepted to be waterproof quality. The IPX4 rating technically means it's splash-proof from any direction up to five minutes. Interestingly, it's actually more "splash-proof" than it's more expensive cousin, the Firefield Tactical NVRS 2.5x50 that is only rated at IPX3.

What is the Actual, Usable IR Range of the NVRS Rifle Scope? 

Many hunters report that 50-75 yards offers the best clarity and resolution to take an ethical shot on live targets. While some buyers have added their own IR illuminator to extend the detection range, it might be best to limit yourself to 200-300 yards with 3x magnification.

Can the Firefield Scope be used with Shotguns or Crossbows? 

Unfortunately, those who live in areas where only 12-gauge shotguns are legally allowed for nighttime hunting, this NVRS scope won't survive the recoil and shock. It's also not made for use on crossbows and air guns.

Is the Quick Detach Weaver Mount Compatible with other Scopes?

Unfortunately, the quick detach mount is only compatible with the NVRS 3x42 scope. The design just allows the scope to come off and back on quickly versus being able to trade out various scopes for the same firearm. However, it would be awesome if Firefield made a daytime scope compatible with this mount!

Can the NVRS 3X42 Scope be Sighted-in during the Day?

It's best to check the manufacturer's instruction manual on this before taking a risk of exposure with your scope. However, if you're set on sighting-in during the day, ensure the scope is facing in the opposite direction of the sun, and keep exposure sessions down to 10-15 minutes at a time. Dusk will be the best time of day for sighting-in and will be the best way to avoid ruining your scope.

Does this Firefield Night Vision Scope come with a Remote Control? 

Unfortunately, this model doesn't come with an on/off remote control. However, the Firefield Tactical NVRS 2.5x50 does include a remote control with the purchase.

What are the Included Accessories with the Firefield Scope?

This scope doesn't come with much. The only "freebie" that you'll receive is the carrying case for the scope. Of course, you'll also receive the operating manual and a warranty card.

Noteworthy Features:

  • Extremely affordable for a Gen 1 NV scope - under $500
  • IPX4 rating for weatherproof protection
  • Compact in size with 9" in length
  • Comes with a Quick Detach Weaver Mount for quick release features
  • Up to 20 hours of battery life with use of IR illuminator

Our Verdict on the Firefield 3x42 (FF16001) Night Vision Scope

To light your trail through the dark, the Firefield NVRS 3x42 FF16001 rifle scope is going to be cheapest way to do it.  You'll be hard-pressed to find a genuine Gen 1 NV scope for less.  If your expectations for clarity quality and your hunting style falls within the close ranges of sub-100 yards, then this scope won't disappoint.  But, we will encourage you to make sure you don't have any of those distracting, internal specks on the inside of your lenses when you get your scope.

Another NV scope that falls under 500 bucks is the Night Owl Optics NightShot scope.  It's not a genuine Gen 1 scope, instead it's digital.  But, don't get skeptical before you read all about it.  It's actually on the mild end for a digital scope.  The NightShot is all about keeping things easy so the hunter can instantly react within that short open window of when an opportunity presents itself.

The NVRS 3x42 scope isn't a waste of money if you know how you hunt and what to expect.  Short ranges under 80 yards with a .308 or lighter in open terrain is the best set-up for this NV scope.  Everyone else might have to pass on this great deal - too bad for them!
