Preface

Prism sights are nothing new exactly, but they have certainly taken off in the last decade or so. When Trijicon brought the ACOG to the market, and it began showing up on military weapons, other manufacturers started paying attention. With their compact size and etched reticles, prism sights quickly became popular aided by their clarity and easy sight picture with magnification. One of the reasons they are so durable is because of their simple fixed magnification, some would also consider that a down sides of prisms. Today we are taking a look at one new option from Apex Optics, and this one carries a variable magnification feature. It also carries a few other feathers in its cap, so lets get into the Apex Optics Vapor 1-4×22 prism sight.

The Apex Optics Vapor Prism

The Apex Vapor is a variable zoom prism sight designed with CQB shooters in mind. Or maybe 3-gun if you are a civilian. With its 1 to 4 power zoom, it gives a great sight picture for those shooting fast and on the move. According to the manufacturer it provides unmatched clear magnification in a compact professional grade optic.

One of the main appeals of prism optics over a traditional LPVO is they eye box. Prisms have a more forgiving eye box that doesn’t require such a refine eye relief. This is ideal for someone who can go from shooting within the room to hundreds of yards downrange in the same engagement. And especially when lives are on the line.

The Vapor incorporates an adjustable diopter to focus the reticle, as well as a capped windage and elevation adjustment. The reticle is lit red by a variable rheostat on the left side, with 11 different brightness settings. The etched FIRE™ reticle has a fine aimpoint as well at a large ring for bracketing close targets. And for targets that are a bit further out, there are several holdover points on the reticle for corrective holdovers.

And if all that wasn’t enough, the Vapor also incorporates a built-in piggyback option for your favorite RMR footprint red dot. Many short range combat weapons incorporate something similar to allow an up close zero parallax aiming option. Additionally Apex Optics offers a 45-degree mounting plate so you can add the red dot sight to the side of the Vapor if you don’t want it on top.

Mounting Solutions

Mounting the Vapor can be done a few different ways. There is a picatinny clamp option that uses several screws to clamp the foot of the optic to your rifle. They also have a QD option that allows you to clamp the optic in place, or remove it with a quick motion.

Additionally they have different heigh foot spacers that allow you to mount the Vapor in a high or low position to better fit your needs. After unboxing the Vapor, I took a few minutes to familiarize myself with these different options and swapped a few things around. I was surprised they even installed stub screws into the screw holes to prevent them getting damaged or filled with crud.

I also took a moment to mount the 45-degree red dot mounting plate with the provided fasteners. Since I had it, I installed an Apex Optics Atom red dot with its compatible RMR footprint.

On the Range

I would end up using the Apex Vapor on a few different rifles, all semi-automatic carbines. Various trips to the range. Shooting distances as close as 20 yards and as far away as 400 yards.

Optical Clarity

Even from the very first time I lifted the vapor to my eye, it was impressively clear. Prisms are usually impressively clear and sharp for their size, and the Vapor was no different. At all points in its magnification zoom, it looked fantastic with sharp detail.

Reticle

After shooting with the Apex, I did a little looking around on what others are saying. I was surprised to see how many people have a problem with the reticle, as I found it to be quite useful. People will always argue over minutiae and their preferences for subtensions and hold-over points.

I found the Fire reticle to be perfectly useful, with a typical large ring around the central portion of the reticle. This large ring creates a much smaller one when the Vapor is zoomed out to 1X, making a nice small point to put on your target while squeezing the trigger. And when zoomed-in, the large circle allows you something to bracket the target.

the reticle offers a variety of hold-over points for further ranges

The various hold-over points on the lower elevation of the reticle give you repeatable marks to hold on your further targets. The indicated values in the manual are handy, but at the end of the day I just see where each point coincides with a given distance and keep those results tabulated.

Controls

The only significant controls on this optics are the zoom feature, and the brightness settings for the reticle. The brightness is similar to everything else you’ve ever tried, there are 11 settings with an off between them.

The zoom feature on the other hand is a bit unorthodox, with a throw lever attached to the magnification ring up front. It does feel a bit odd reaching to the front of the optic to adjust the magnification. But because its so small though, its not a far reach. I did find one thing that I wouldn’t call a problem, but felt weird. The throw of the lever is pretty short, and when it reaches the end of either end, there is a solid stop. So you don’t want to get too aggressive pressing on it.

Durability

Obviously time and use is the best way to test a products durability. While I fully plan on giving the Vapor a solid wringing out over the next year or so, that takes time. Fixed prism sights in general are tougher than variable magnification optics, but the Vapor itself is also variable. So it stands to reason that it might be less durable than a fixed prism sight. Time will tell.

Value

The Apex Vapor is not what I would consider an inexpensive optic, with an MSRP of $950 it is certainly not entry level either. Additionally, the Vapor has a relatively specific purpose, which makes purchasing the Vapor a very deliberate choice. If you are looking for a variable zoom prism though, there aren’t so many options.

Perhaps it would be somewhat comparable to evaluate it against a 1-4 power LPVO. Of which there are many options and you can probably get them for a lot less than the Apex Vapor. But a bunch of cheap 1-4 LPVO’s does not equate to what this optic offers you. In fact, comparing it to some of the nicer 1-4 LPVO’s like those from Steiner, Trijicon and Leupold would be a better comparison. The Vapor is cheaper than those options, and other than tactical style turrets it has many of the same benefits in a more compact sight.

next to a small LPVO riflescope, the Vapor has a smaller footprint

There are a couple larger 4x and 5x prism sights from companies like Steiner and Burris, but they are fixed power. And depending on the model they might be only slightly cheaper.

Mounting Options

The Apex Vapor is available with a couple different spacers to change the optic height. Additionally you can get it with either a screw clamp foot or a QD foot. One can give you fast optic swap, and one is more compact and less likely to get snagged on your gear. Both of them give a solid interface with the host weapon.

Pros and Cons

Compact Size	Costlier than Most Smaller Prism Sights
Sharp and Clear Image
Very Usable Reticle
QD Foot for Faster Install and Removal
Short 45-Degree 1-4X Throw
Easily Mounted Piggy-back Red Dot
Tethered Caps That Double as Tools
Etched Reticle

Final Thoughts

I really quite like the Apex Optics Vapor. I’ve been on an LPVO kick for a few years now, and the Vapor’s size is refreshing while still bringing the sighting options. The images seen through the optic are fantastic and clean, and its factory piggy-back red dot options make it easy to pick. And Apex Optics thought through the Vapor, with variable mounting heights and QD mount. If you are considering a high quality 1-4 power sight for your carbine, it certainly is worth taking a look at before making your decision.

Vector Optics Paragon Micro Prism Magnifier Combo

July 3, 2026Optics, Product reviewmagnifier, micro prism, optic, paragon, sight, vector opticscoldboremiracle

Introduction

One of the most popular sighting configurations in use today, is the use of a Micro Prism and magnifier combo. Micro Prism’s are basically a compact scope with a reticle. Commonly they are used in similar situations as red dots, for shorter range firearms. These Micro Prisms give some shooters a more precise aim due to optical alignment issues. Folks with an astigmatism may have trouble defining a red dot aim point, whereas with a prism they can focus much better. The magnifier adds a level of optical magnification for additional precise placement on targets. This configuration is a bit newer to me, but I’ll walk you through my own experience as we test and evaluate the Vector Optics Paragon Micro Prism magnifier combo.

Vector Optics Paragon

Paragon Prism

Vector Optics makes a variety of different optical sights, including rifle scopes, red dots, and todays topic; the Paragon Micro Prism and magnifier. There are several different options including 1x, 3x, and 4x micro prisms. And they also make both a 3x and 5x magnifier to put behind the micro prism.

The Paragon Micro Prism uses two push-buttons to power up the reticle. You can power it up or down by holding the front button, while toggling brightness is done using either button. On the left side of the optic there is a battery housing for the CR3023 lithium cell, which makes it easy to change without messing up your zero.

on longer rifles like this 16-inch AR, the 3x magnifier allows shots well into a quarter mile

Zeroing the reticle is done using a windage and elevation adjustment screw on the top and right side of the optic. A small flat screwdriver works great for adjustments. At the rear of the optic you can adjust the diopter for best focus. This optic can be a standalone sight, giving you a simple 1x view of your target area.

Paragon Magnifier

Adding the Paragon 3x Magnifier to the Micro Prism gives you an additional magnified image of the target area. And it does this without interfering with the prism or point of impact. The magnifier comes with a spring loaded mount that allows you to quickly pop it out of the way should you wish to use the simple 1x of the prism sight. And just as quickly snap the 3x back into place should you need a closer look at the target.

Vector’s spring-loaded mount has a small button on one side that when pushed, allows the magnifier to swing 90 degrees out of the way. In this position the magnifier is off to the side of your sight rail. Much like the prism, the magnifier is easily mounted on a picatinny rail using a small torx driver.

You might wonder why the magnifier has elevation and windage adjustments when it features not reticle inside. That is to allow you to center the magnifier over the reticle as seen through the prism optic in front of it. It also has an adjustable diopter at the rear to maximize focus and clarity.

Host Rifles and Mounting

I have used the Paragon combination on a couple different rifles, both being small frame AR style rifles. The first one is a custom rifle I put together with a 16-inch upper, and the second is the Dark Storm Industries DS-25 MFR. The latter is more of a fighting rifle setup, which tends to be the type of rifle this sight configuration is used for.

Finding the right eye relief is paramount for mounting these optics. Putting them in the right spot that allows you to use either the prism alone, or the prism seen through the magnifier. Once the right eye relief is found, I snugged the two optics down to the pic rail.

Adjusting the reticle in the prism, note similar adjustment screws on magnifier

I was immediately irritated with the misalignment of the reticle as seen through the magnifier. So in no time I adjusted the windage and elevation on the magnifier until the reticle of the prism was centered. I tested the swing-away feature of the magnifier a few times, and then I was ready to hit the range.

Shooting the Paragon Combination

I would end up shooting with the Paragon combo over the course of several range trips on both host rifles. I like the 1x power of the prism alone, it is fantastic for engaging targets that are not particularly far away. The same type of shooting you’d do with a red bot perhaps.

here you can see both the red and green reticle colors looking downrange. As you might imagine, it looks much better than the pictures show here

Engaging targets from 20 to 100-yards was very easily done, and allows the broad field of view. With head up and both eyes open, you can stay very aware of the target area and your own surroundings.

shooting the rifle with the Paragon Prism alone

Snapping the magnifier into position would instantly give you the 3x power to add more precision to your shooting. Picking out targets beyond 100-yards was surprisingly easy, and the 2 MOA center dot of the reticle was still small enough to make some pretty good hits as far away as three to four-hundred yards if you could hold steady enough.

Optical Clarity

Vector Optics’ products have proven to be very good optical quality in my experience. And the Paragon combo was no different. Flaws are a little less obvious on lower power optics, but I wouldn’t be surprised if Vector is manufacturing OE products for other brands you would consider better or higher quality.

Bright images with little aberration were easily focused using the adjustable diopter. The brightness levels of the reticle were suitable for indoors and bright sunny day shooting.

Reliability

I don’t see any reason to doubt the durability of the electronics inside the Paragon Micro Prism. Some might suggest that its foreign manufacture are reason alone to doubt it, and I’m open to that possibility. But other Vector products have stood up for me over the course of years, and continue to work great. So I am perhaps a little more lenient on this topic.

Fasteners and materials used appear to be more than adequate, as does the mechanical hinge mechanism and lock. It really does feel like a nice product, comparable to brands that are considered by some to be much better.

Usability

The push-buttons are low profile, and I expect they are less likely to be damaged when compared to a rotary rheostat knob like comparable optics. Adjusting brightness and color is quite easy using the buttons. And the side mounted battery cover it easy to grip as well.

The low profile adjustment screws are easy to get at with your screwdriver, and wont get caught on anything. And adjusting focus of one or both optics is easily done from the shooting position if needed. Having a circle dot reticle also gives you some dexterity in your aiming.

Value

With a combined MSRP of under $230 I find this combo to be a good value. If you are the kind of shooter who’s life hangs on your sights working, you might feel the need to spend more. But for a typical hobbyist or sport shooter, the Paragon Micro Prism and Magnifier would probably be fine for your purposes.

Pros and Cons

Vector’s Paragon optics are pretty impressive considering their price. A comparable set from another manufacturer will easily cost double or more. I like the reticle, and its dual color illumination, the fine dot makes a precise aiming point. While the larger circle gives a fast bracket of the target when targets are close and your moving fast. The clear view and easy operation make it a great sight system. The only thing I wish they’d done was make it a compatible footprint with other popular brand optics like Trijicon so that you could use aftermarket systems like those from Unity Tactical.

with magnifier out of the way, the 1x prism is easily accessed

Conclusion

If you are looking for a prism/magnifier combo, I recommend you should at least look at these to see if they meet your purposes. There is a lot of money to be spent on comparable systems, and this might do everything you need for much less.
