D. Watson –
I bought four of these, and one was defective (had two defects), but otherwise I love.
Other than the defects, I would rate this sight 5 stars, but I have to deduct at least one star for the two defects that made one unit unusable. Given the defects on one out of the four units I bought, I rate it 4 stars.
This will be a long, detailed review because I own not only this Sightmark Volta, but also its main rivals, the Holosun HS512C and Holosun HS510C, and its predecessor the Sightmark Element Mini Solar, so I’ll be making some comparisons below.
First, the one (out of the FOUR that I bought) had two defects:
1) The battery cover was impossible to remove to install batteries. This was a defect, because I bought FOUR, and the other two units opened fine, but the third one was impossible to open the battery compartment. I almost decided to keep it and use it simply as a solar sight, because the solar panel on it is quite powerful, and it works as a red dot sight without any batteries installed, in 90% of lighting situations, just as a Trijicon RMR dual-powered (solar/tritium) sight does. However, For those 10% of lighting situations where the solar panel is not enough (such as when at an indoor range, or shooting from a shaded outdoor area at a target that’s in the bright sun), I need to be able to use battery power, and this third unit had a defective battery door that simply WOULD NOT OPEN. I even tried using powerful magnets, but the battery door is aluminum or plastic, not steel, so it would not open with magnets, either, and the little bit of steel in the retaining screw wasn’t enough for the powerful magnets to open the battery door that simply WOULD. NOT. OPEN.
2) The second defect on my defective unit: when I switched from the high-mount to the low-mount, one of the four screws that was supposed to attach the mount was the wrong size, and would not work. I mean, it was so obviously the wrong screw, not only because it wouldn’t fit, but also because it even looked different from the other screws — the defective screw was gray, while the good screws were black — so it had obviously been packaged with the wrong screw.
Now that I’ve got the defects out of the way…
GOOD POINTS (and ADVANTAGES of the Volta over its Holosun rival)
– Perfect size! The Volta is slim in width, so it’s especially suitable for narrow rifles such as lever-actions, single-shots, or rimfire rifles that have a narrow profile. It’s also compact enough to use on target pistols, target revolvers, or hunting revolvers (if they have a true Picatinny rail). Its main rival, the Holosun HS512C, is wide, fat, and chunky by comparison.
– Choice of mounting heights, low mount or high (absolute co-witness) mount. Its main rival, the Holosun HS512C, only comes with a high mount, making it less suitable for traditional rifles and shotguns with traditionally shaped stocks.
– Uses standard AAA batteries! This is a big plus. Its main rival, the Holosun HS512C, requires a CR2032 battery.
– Comes with a protective cover, and a sturdy, high-quality one too. Gun cleaning solvents can damage precision coated optics, so a cover is essential. Its main rival, the Holosun HS512C, doesn’t come with a cover, nor are there any available from third-party manufacturers.
– Solar backup, which works even without any batteries in the sight! In fact, under normal conditions, you never even have to turn it on, because the sun or indoor lighting provides all the light you need, so under normal lighting, even if the batteries fell out, you would still be good-to-go! Its solar backup is therefore better than its rivals the Holosun HS512C and Holosun HS510C.
– Comes with a protective cover, and a sturdy, high-quality one too. Gun cleaning solvents can damage precision coated optics, so a cover is essential. Its main rival, the Holosun HS512C, doesn’t come with a cover, nor are there any available from third-party manufacturers.
– No special tools needed for installation (attachment to your gun’s rail), just a standard screwdriver or small coin. I found that a dime works well for installing and removing the sight from your rail. For windage, elevation, and the battery door, a standard screwdriver will work. Its main rival, the Holosun HS512C, requires a special tool (Torx T10) for installation and removal, and a special Holosun tool (which doesn’t fit on keychains) for adjusting the windage and elevation knobs — Holosun tools for other Holosun sights will not work on the Holosun HS512C, and neither will coins or screwdrivers, a major drawback of the Holosun.
Bad points:- Saying the biggest flaw is its instruction manual might sound like nitpicking, but it’s not. The Volta’s Instructions were obviously copied from a different model sight (the SIghtmark Element Mini Solar, which I also own), which means they are incorrect instructions for this sight. Apparently, Sightmark just slapped a photo of the new sight on the cover of the instructions for the older sight, so there is a lot of incorrect information in the instruction manual. It’s odd that the instructions would still be so wrong, considering that release of this sight was delayed over a year from its introduction at the 2020 Shot Show, so Sightmark had over a year to correct the instructions and revise them to apply to this model, rather than copying the instructions from an entirely different sight which has different adjustment and zeroing procedures!
– Battery instructions say to install according to the polarity marking on the sight. But there are no polarity markings on the sigh, so you have to just guess which of the four possible ways to install two AAA batteries is correct.
– The battery door is untethered and very, very hard to close with batteries installed. The battery screw turns less than 1/8 turn, making me afraid the batteries are about to fall out any time! If the batteries do fall out, the battery door is untethered, so it will fall on the ground and get lost. Fortunately, the solar backup means the sight will still work if the batteries fall out. If the batteries do fall out while shooting, I will revise this review to subtract at least one more star.
– A tool (screwdriver) is still needed to adjust windage, elevation, and open the battery door. Although a dime works for installation (attaching the sight to your gun), a dime is too thick to use for the battery door and the windage and elevation knobs, so you’ll still need a screwdriver or pocket tool for zeroing and battery changes.
– Compared to its main rival, the Holosun HS512C, the Sightmark Volta only has one choice of reticle, a simple red dot. This is probably the Holosun’s main advantage over the Sightmark, because the Holosun has a choice of a circle-dot reticle or a dot reticle just by pushing a button. This makes the Holosun reticle a better choice for shotguns, IMHO, especially for skeet shooting or birding.
Benefits shared by both SIghtmark Volta and its main rival, the Holsun HS512C (a tie or draw):- Both are closed reflex sights, a better design than open reflex sights in which dirt or debris could fall into the sight and block the emitter.
– Both have a streamlined design, with no protruding knobs or battery tubes to get in the way of your vision! This not only looks modern, but gives you a better view of your target when shooting both eyes open, as these sights are designed for.
– They both have large sight windows. The Holosun HS512C has a slightly larger sight window, but they’re both large enough.
– Without its cover on, the Volta is about one ounce lighter than its main rival, 7.2 ounces vs the Holosun HS512C weight of 8.2 ounces. However, when you add the Volta’s cover, then they’re the same weight, so it’s practically a tie.
– Incredibly long battery life, many years of constant on! Its rival the Holosun HS512C also boasts a long battery life, but only when choosing the single dot reticle — when using the HS512C with a circle-dot reticle, the battery life will be much shorter, about one year.
– Both have solar backup, although I much prefer the Sightmark Volta’s solar backup because it works well even with no batteries installed, and the Volta’s solar-powered red dot is always on, even when the sight’s electronics are turned off!
BAD POINTS ABOUT THE VOLTA (in addition to the defective unit I received):
1) Doesn’t fit non-standard (out-of-spec) Picatinny rails that are narrower than the standard Picatinny rails. I have a Weigand rail (for a Ruger GP100 revolver) which Weigand calls “Weigatinny” as it is about 99% the same as a Picatinny rail. Every other red dot sight I’ve tried fits fine on the Weigand rail, but the SIghtmark Volta fits too loosely and wobbles, which would make it inaccurate on that rail.
The Volta simply cannot be tightened enough to fit on the “Weigatinny” rail, even though it’s just a fraction of a millimeter narrower than a mil-spec Picatinny rail. The Volta is picky about rail widths and demands mil-spec rails. Too bad, because this would be a perfect-sized sight for a Ruger GP100 revolver!
End of list of flaws. Other than that one flaw (and the mis-printed manual, and that one out of FOUR Sightmark Volta’s I received was defective), I loved the Sightmark Volta! But I can’t give it five stars due to the one defective unit I received.
Ben –
1st off this is not my 1st sight mark I have the wolfhound and the wolverine also.. the wolverine series of red dots are fantastic for the money but they lack the solar power cells that this Volta has .. I really like the Voltas low profile and internally housed illuminator this gives the Volta a layer of durability that other optics with open illumination don’t have ..the dot is crisp and the glass is clear additionally the optic has so far held up to recoil and maintained a zero that said I would like to have some more time with it to see how it holds up over time but all and all I’m impressed 10/10 if it had additional reticle and color options like some of holosuns offerings I’d say 11/10 🙂 very happy

It looks sexy. It mounts very well and secure. I use loctite to keep screws from slipping under recoil.
The dot is crisp and clear and the battery option and solar options are just as advertised. Good product with a compelling battery life. No detectable parallax. . .
However I was disappointed to find that the solar panel glass had shattered against my utility belt while I had my rifle slung and was walking from my truck to my home. My particular failure was critical because the solar function stopped working completely and only engaging the battery turned on the dot. I’m currently researching plexiglass that I will add to my solar panel to reduce the risk of failure in the future. Oh, and the reason I’m still somewhat happy is that SightMark customer care was prompt and had my return processed and a replacement sent to my door in less that a week.

I was impressed with the Volta. The red dot was very clear and bright. The auto brightness feature works great when transitioning between environments.

Used and reboxed and did not work, tool marks, diry and batteries were installed, pre-owned and reboxed, not pleased with this.!!!

the products did not meet my point. the second times was the right one , and had been pass half month ,I did not received the refund from your Company .

I have some land out in the middle of nowhere. I needed something that would keep me from worrying about batteries. The price was right, and it worked perfectly for my AR pistol. The red dot stays on during the daytime without running the Battery down. This is exactly what I need if a surprise desires to come out of the woods. The fit and finish are beautiful. The Volta has multiple brightness settings, so it’s perfect for indoors and outdoors. The lens is clear, and the red dot doesn’t bleed or have a starburst effect. It’s a perfect sight for An AR or any semi-auto.

I really liked this red dot. I feel like it’s a good size and has a very modern look. Additionally, the Volta dual power red dot gives you a good field of range making it easy to ensure you can keep both eyes open. It’s worth mentioning that indoors this does dull the color a bit but that would be the only thing I would consider a “downside” however, that’s just because it automatically dims and brightens dependent on you’re environment. Like I said, I really liked this reticle and would recommend it.
