A red dot sight (RDS) or holographic sight can work wonders when your target’s up and close and personal, but what about those targets out at a distance? There are no zoom functions, so with ranged targets, they aren’t any good. That’s where the magic of magnifiers comes in. Quality ones serve to enhance your optics and shooting by adding range, yet the question remains which ones are worth it? We researched dozens of magnifiers, 3x in particular. From our reviews of 10 top-rated products to our buyer’s guide that follows, we hope to help you find the best 3x magnifiers for our next outing.
With no more time to waste, let’s jump right into our top 10 countdowns.
10 Best 3x Magnifiers:
The Vortex Optics VMX-3T Magnifier is a flip mount combination that enhances your red dot sight. It uses a push-button design for quick placement and removal when you don’t need it.
This simple and lightweight magnifier is durable, and it doesn’t need any special sight-in. It can work with mostly all red dot sights, but it’s not recommended for use with prism scopes.
Consumers praise the Vortex 3x magnifier for how easy it is to use. The flip-to-side design allows for quick engagement and disengagement. It’s especially versatile as it works for installing at a lower 1/3 height or absolute co-witness height.
Appreciation is also seen for how well the magnifier resists water and fog
There have been complaints about eye relief since some feel as though it’s too small and uncomfortable.

- Small eye relief
The UTG 3x Magnifier is a flip-to-side magnifier that provides a wide field of view when used with both RDS and holographic sights. It’s adjustable from the windage to the eyepiece.
This also features a quick-detach lever locking mechanism in the mounting base for simple installation. It’s designed to last, built to withstand wear, fog, and water.
Our UTG 3x magnifier review discovered that consumers enjoy the user-friendly layout. It’s ergonomic and quick to flip to the side and out of the way.
Also, it mounts easily enough, and it remains secure.
For the complaints, some shooters say that the minimal eye relief can have you sitting too close, more so when you have to account for recoil.

Many consumers enjoy how well-built this magnifier is, and they say it feels as though it can hold up to rough use. They also appreciate the small footprint since it sits at just under 4in. in length.
Further appreciation is seen in the flip function as users believe they can move it back and forth with ease. As for the price, there are some complaints that it’s a tough high, but many feel that the construction and clear view makes it worth it.
There may be a break-in period, however. The eye relief isn’t all that impressive, so it can take some getting used to.
- Durable construction
- Compact style
- Flips quickly
- Break-in period
The Hammers 3x Magnifier Scope is designed with all marksmen in mind. There’s a good deal of adjustability when it comes to windage and elevation so you don’t have to zero in.

From what we’ve gathered, consumers feel the lens is high in quality. The glass is clear, and the overall optics is bright enough for use even when the sun isn’t gleaming down.
They also like the protective caps that cover the adjustment knobs as well as the cap for the lens. Also, for further protection, users appreciate the rubber-armored grip.
Some users did feel that, in spite of being light in weight, the magnifier is noticeably bulky. This may interfere with your backup iron sights.

There’s quite a bit of praise about the hybrid unit altogether that saves you from buying a holographic sight and magnifier to go with it separately. Shooters also feel that it’s rather user-friendly in how easy it is to install and use.
The entire piece seems built well and meant to last through any situation you may think to put it through. Also, it’s easy enough to adjust, and this still provides you with the pinpoint precision of your target when magnified.

Consumers feel that the flip functions well too. There’s enough eye relief that it feels generous, and many claim that it offers ideal comfort.
Another high point is how well it withstands water in general. Also, the performance doesn’t appear hindered under foggy weather either. You may not get much out of this magnifier in low light conditions, however. The clarity seems to drop unless there’s an optimal amount of light.

Beyond that, there were many positive comments about glass quality. The optics appear clear under magnification, and the mount helps hold the center well. Concerning the overall build quality, it seems rugged enough to hold up over multiple, frequent uses.
The main issue consumers have is the fixed design. Even though you can put it on and take it off fast, you must take it completely off and have somewhere to put it as it doesn’t simply move to the side like flip mounts.
- Mount holds center well
- Glass is high-quality
- Reliable construction
- Fixed-mount takes time to use

A major issue some consumers had, however, is that they feel like it doesn’t lock into place well. Some report the magnifier sliding off while in use.
- Fast slide-to-side design
- Good clarity
- Quality alignments for elevation and windage
- The chance that it can dislodge out of place
Factors to Consider When Buying the Best 3x Magnifiers
RDS and other optics are only increasing in popularity as the years go by. In fact, many shooters moved beyond using them on rifles and have extended their use to handguns considering how beneficial they can be.
It’s no surprise then how many gun users are turning to the likes of a holographic sight with magnifier and others like it to get the best of both short-range shooting and medium to long-range shooting.
In light of our top 10 reviews, we understand how you may still be on the fence on what a 3x magnifier is actually the best. It’s subjective based on your needs, so we’ve created a buyer’s guide to help you understand more about the magnifiers to make your decision.
There are two ways to mount your 3x magnifier: flip or fixed.
A flip-to-side style scope magnifier is highly recommended by us and other shooters for its versatility. You can swap from 1x to 3x magnification in a split second, a much-needed skill for tactical and hunting scenarios.
Fixed mounts aren’t the most recommended seeing as you have to either use the 3x or completely remove the magnifier to shoot up close. That can take up valuable time, so you’ll have to be careful about how you’re using your gun if you want a fixed mount magnifier.
For instance, this may not be much of an issue in some competitive shooting.
RDS lacks any sort of eye relief, so it’s important that a red dot magnifier has it instead. Since we focus on 3x magnifiers, the eye relief should only be a couple of inches. That should be comfortable enough to handle the zoom.
When choosing a 3x magnifier, you also want to keep in mind extra features beyond the zoom.
Check out the lens itself. Quality magnifiers offer anti-fog coating, for instance, so you can shoot well under various weather conditions.
Many are offer water-resistant or waterproof, surviving under light or heavy rain depending on the water rating.
Also, consider the field of view available as this will determine how fast you can acquire your target.
