Taking A Peek At The Modern LPVO
Magnified rifle optics have been around for many decades. The accuracy of rifles started to improve in the first half of the 1800’s. This allowed people to make hits at longer and longer distances. It also increased the need to spot targets at longer ranges. Eventually, a telescope was added to a rifle and the telescopic sight was born. Telescopic sights started out as something for shooting at longer ranges, which limited their utility at closer distances. People soon started realizing the need for something that worked at both close range and long range, and thus the low power variable optic, or LPVO, was born.
Germany has a long history of creating precision optical gear, so it’s no surprise that the first LPVO was made for a German rifle. In 1922, Carl Zeiss rolled out the “Zielmulti” scope, one of the very first low power variable optics. The scope (and others like it) was used by hunters who needed to quickly transition between targets at different ranges. For most of the 20th century, though, the rifle scope was thought of as something used only at long distances (over 300 yards) and only by people such as snipers or hunters looking for long-range prey.
In the 1990’s, though, things changed. America’s armed forces were frequently fighting in urban environments where hostiles were intermixed with innocent civilians. It became important to have good target acquisition and verification at ranges past 50 yards. This meant finding an optic that worked while our soldiers went from room to room clearing houses and could also be used to peer down an open street.
Enter The LPVO: Low Power Variable Optic
The answer was the Schmidt & Bender “Short Dot” LPVO, which was created in the mid-1990’s as a response to the experience of Special Forces units fighting in the Battle of Mogadishu. The Short Dot codified many of the features found on today’s LPVOs.
- 1-4 power with a 20mm front aperture
- External adjustments for elevation and windage in 1/2 moa clicks
- BDC (Compensation) markings inside the reticle for 5.56mm and .308 ammunition
- A range of scope illumination settings
- Shorten the scope as much as possible
- A short throw lever on zoom ring to rapidly change the power from one setting to another
The rest of the military began to see the advantage of an LPVO. Soon variable power scopes were in common use by regular troops as well as more elite units.
The mid-1990’s was also when 3 Gun competition was starting to take off. Competitors in that sport quickly saw the advantages of an optic that would allow them to quickly shoot targets at close ranges yet still be able to dial up the power to hit small targets at 300 yards and beyond. They put scopes like the Leupold Mark 4 CQ/T into use, and a new division (TacOptics) was created to level the playing field between competitors with a magnified optic on their rifle and those without.
Reasons For And Against Using An LPVO
I spoke with Michael Branson, the Product Marketing Director at Swampfox Optics, about what an LPVO can and can’t do for your shooting.
“The biggest reason to use an LPVO is that there is limited space on top of your rifle,” Branson said. “If you know beforehand what type of shooting you’ll be doing, you can adjust your optic to fit your need. Non-magnifying red dot optics are great for close ranges and more powerful scopes in the 4-16x range are excellent for long distances. An LPVO gives you options. You can shoot just about anything, anywhere with one on your rifle. An LPVO gives you flexibility. It’s intended as a do-it-all scope that can handle most common engagement distances, especially in defensive situations.”
Are They A Jack Of Trades Optic?
“An LPVO does a lot of things reasonably well,” Branson continued, “but it’s not the best at any one thing. I think that a red dot or a prism is a better choice for up close work. For shots that are further out, a higher power scope, like something in the 4-16x range is a better option. Those scopes have features like parallax correction and first focal plane reticles. These sort of things really help get your shots on-target at 400 yards and beyond. In addition to this, LPVOs are heavier than a red dot, and more cumbersome. However, they are lighter than high-powered precision rifle scopes.”
I asked Branson if he thought that going with a higher maximum power is always a good choice when buying an LPVO, and this was his response. “Low power variable optics started out in the 1-3 or 1-4 range, and there is a reason for that. At higher powers, you lose eyebox and cheek weld space, and the scope is darker because of reduced light transmission. You gain more magnification which in turn enables better hits at longer ranges. Also, because of the tighter field of view, your target acquisition times grow longer as you increase the power on your scope.”

Sig Sauer TANGO6T – MSRP $1,429 : The TANGO6T is the current optic of choice for the U.S. military, and with good reason. It has a great feature set for the price, and is built to handle everything an infantryman can throw at it.
Leupold Mark 6 1-6×20 – MSRP $2,859: Leupold is one of the first people to make a rugged LVPO for military and law enforcement use, and that experience shows in the Mark 6 line.
Is A Low Power Variable Optic Right For You?
The answer to this question depends on how you plan to use your rifle. If you’re looking for a close quarters defensive gun, a red dot or prism optic might be your best choice. If you’re looking to stretch your shots out to 300 yards and beyond, then definitely consider something that starts at 3 or 4 power and goes up from there. For applications where you’re just not sure of the distance of your target, such as a scout rifle, an LVPO might just be your next optic.
There is a lot to be said in favor of the LPVO as an all-around, do-it-all optic. The author has gone over the advantages quite well. I am a bit of a fan of the idea myself. However, it seems to me that LPVOs as a class have three great weaknesses, which may or may not matter to a particular end user, but.
1. They’re fragile. They’ve all got more moving parts than a fixed power optic. And, at the end of the day, after we finish reading the ad showing a guy driving nails with a telescopic sight, it’s a thin tube of lightweight aircraft aluminum with thin glass lenses inside it. We’ve heard a lot about the war in Ukraine, but one of the things of consequence for this discussion, which we don’t hear very often, is that a lot of those guys pay for their own gear out of their own pockets. A lot of them bought into the LPVO hype. And the thing about LPVOs is, when you bolt one onto a rifle and put it in the hands of a guy living in a muddy trench, a guy who periodically has to throw the rifle to one side while diving into a bunker under mortar fire, they break. They break a lot. They break a LOT. Even the expensive ones. Yes, that includes the German and Austrian brands that cost more than your car. The only optics that hold up to the conditions to which they are subjected in trench warfare are Trijicon ACOGs. Does this matter to you? If the rifle is a range toy, probably not. If it’s a home defense rifle, probably not. If you bought it with the intent of relying on it in “SHTF” and “WROL,” then yes, it matters a great deal how likely the lenses are to shatter from a few bumps while you’re fleeing cannibal raiders through a frozen swamp.
2. The LPVO is often sold as having a big “eye box.” That’s the area behind the scope from which you can see through it and pick up a usable sight picture. It is related to the exit pupil–objective lens diameter divided by magnification–but glass quality, lens coatings, surface finish of the scope’s internals, QC with which the scope was built, first focal plane vs. second focal plane, and a number of other things about the design affect it a great deal also. Generally speaking, the eye box is one of the first things the designers sacrifice to get that higher magnification ratio. First focal plane LPVOs have a smaller eye box than second focal plane, and the difference is not small or subtle. And so on. If you are contemplating using an LPVO on 1x most of the time as a close range optic, this matters. A 1-4x LPVO on 1x is a mediocre substitute for a red dot, when it comes to running and gunning, making quick shots when it counts. A 1-6x is unavoidably going to be worse on 1x than 1-4x. 1-10x is worse yet. You can train around it, you can get used to it, you can become highly proficient with it, but even on 1x it will slow you down, noticeably, measurably, compared to a red dot. The three-gun guys prove this in competition every day. You can piggyback a red dot on top of your LPVO, smack it against every protrusion, and lift your chin up into the air to look through it for those “movers” close in, I guess. What I am saying is, there are trade-offs here. An LPVO gives you a lot of weight savings compared to a red dot and a magnifier on a hinged mount, and it’s generally going to be more rugged, relatively speaking, but it WILL slow you down, and the closer in you are, the more you’ll feel it. A pistol red dot on a piggyback mount is exposed, extremely fragile, and on an axis far higher and far removed from the scope’s axis. That height difference and the impossibility of getting anything like a proper cheek weld is going to slow you down too. You pays your taxes and you makes your choice.
3. Almost all LPVOs have fixed parallax at 100 yards. People will tell you that doesn’t matter. Let’s do a test. Get your rifle, with your favorite LPVO bolted on, put it in a cradle rest, and aim it at a target at, say, 25 yards. Now, without touching or moving the rifle, move your head around a bit in the eye-box. Watch that reticle swimming and wobbling side to side. Whee! You can give yourself motion sickness this way! And you just might be able to introduce enough parallax here, depending on the exact optic you’ve installed, exact height over bore, exact lighting conditions, exact size of its eye box, and so on, to whiff on a head shot completely at only 25 yards. Yeah, I know, cheek weld. Yeah, I know, nose to charging handle. Yeah, Grandpa didn’t need no fancy adjustable objective when he was hunting deer. Grandpa was shooting from a rest in a blind on a bright clear sunny day and the deer weren’t shooting back. Maybe you only shoot at a square range, and that’s fine, but the three-gun guys, who run and gun, can tell you that it happens. You don’t have to be trying to castrate a horsefly surgically from a quarter of a mile for parallax to throw your point of impact off enough to matter. If your cheek weld and your head position are not perfectly consistent and consistently perfect, the LPVO is absolutely unforgiving. Optics with 100 yard fixed parallax will exhibit troublesome levels of this a lot more close in than at distance. Remember, the LPVO’s sole reason for existence is to be a do-all optic that allows you to make fast shots in close. It’s great until it isn’t. Yes, there are now a handful of LPVOs with side focus adjustable parallax. You can find them if you dig around the dark corners of Amazon and eBay. Every one I’m aware of is from a Chinese airsofter brand, and I’d be surprised if any of them wasn’t worse in every way than just using the irons.
I like LPVOs. I like the concept. It’s very promising. The execution is, in certain areas, lacking. That doesn’t keep me from using them on range toys. But I am aware of their inherent limitations. I, personally, wouldn’t go to war with one as my primary optic. If I were in a muddy trench in Ukraine right now, I’d stick with the irons. Your mileage may vary, of course.
