LPVO Scope Explained: 1-6x, 1-8x, 1-10x and Focal Planes

An LPVO scope is a rifle scope that zooms from true 1x, like a red dot, up to 6x, 8x or 10x for distance, all in one optic.

The red dot crowd and the magnified scope crowd have been arguing across my counter for years, and the LPVO scope is the reason a lot of them finally shut up and shook hands. Over a career of over 20 years, I have mounted more optics on rifles than I can even ever imagine to remember, and here is the plain version: an LPVO (low-power variable optic) gives you a red dot style picture on the bottom end and a real scope on the top end. You turn one ring to get from one to the other. That is the compromise, and it is a good one.

“True 1x” is the part that matters. On a good LPVO the bottom setting shows the world at the same size your naked eye does, so you can run it fast up close. Crank it up and the same optic lets you see what you are shooting at a couple hundred yards out. Vortex, who sells a bunch of these, calls the 1-6x “standard” and the most popular range, and the top end usually lands on 4x, 6x, 8x or 10x.

What Does an LPVO Scope Do?

Think of it as a red dot and a hunting scope that got married and moved into the same tube. At 1x you shoot with the target the same size you see it, which is what you want inside a room, in thick timber, or on a hog that just came out of the brush at 30 yards. Turn the power ring and you get magnification for the shot across the field.

A red dot cannot do the second half. A traditional 3-9x hunting scope cannot really do the first half, because 3x up close is like looking through a paper towel tube (ask me how I know). The LPVO covers both, and that is why Vortex lists everything from “door-kicking to engaging targets out to hundreds of yards” and hunting in thick cover as its job.

Here is what the magnification on an LPVO scope buys you. These numbers are simple math: the target looks as big as it would if you were standing that many times closer.

Look at that 6x row. A deer at 300 yards looks like it is standing at 50. For most of the shooting most of us do, that is plenty.

1-6x, 1-8x or 1-10x?

This is the question I get more than any other, and my answer is 1-6x for most people. Here is why. The more magnification you add on top, the tighter the eye box gets (the space behind the scope where your eye can sit and still see a full picture). MyGunDeal put it plainly in their eye box write-up: the eye box is generous at 1x and “shrinks as you increase magnification,” so a 1-10x at full power is fussier about your head than a 1-6x at full power. Physics does not care how much you paid.

So here is the thing: buy the top number you will use. If you shoot past 400 yards on purpose, a 1-8x or 1-10x earns its keep. If you hunt the woods, run a home defense carbine, or shoot 3-gun, the 1-6x gives you nearly all the reach with an easier picture to find. Moving on to the 1-4x, those still exist and they are light, but I think most folks will wish they had more on top once they get used to the zoom.

First Focal Plane or Second Focal Plane?

This one confuses people, so let’s go through the mechanism instead of the vocabulary. Inside the tube there are two spots where a reticle can live. Primary Arms explains it well: in a first focal plane scope the reticle sits between the objective lens and the magnification parts, so it grows and shrinks with the picture. In a second focal plane scope it sits between the magnification parts and the eyepiece, so it stays the same size no matter where the dial is.

Why should you care when you shop for an LPVO scope? Holdovers. On a first focal plane scope, the hash marks under the crosshair mean the same thing at 2x as they do at 6x. On most second focal plane scopes, Primary Arms notes, those marks are only correct at one setting, usually full magnification. Dial it back and your 300 yard mark is lying to you.

The flip side is that a first focal plane reticle gets tiny at 1x, and Primary Arms flags that it can be hard to see in low light. The good first focal plane LPVOs fix that with a bold center (a big illuminated circle or horseshoe) that stays readable at 1x while the fine marks shrink out of the way.

Here is where I land: if you plan to hold over at distance, buy first focal plane. If the rifle is for the woods and you will zero it and shoot center mass inside 200 yards, a second focal plane LPVO with a bright, fat reticle is a fantastic scope and usually easier on the wallet.

Eye Relief, Eye Box and Mount Height

Remember that an LPVO is only as fast as the setup under it. When somebody tells me their LPVO has a terrible eye box, the first thing I check is whether the rifle puts their eye where the scope wants it.

Start with mount height, because an LPVO scope sits closer to your face than most people expect. The common LPVO AR-15 mount heights are 1.5 inches, 1.93 inches and 2.26 inches, with the 1.93 height lines up with a natural head position on a typical AR for most people. If you are not sure what you have, run the numbers through our scope ring height calculator before you order anything.

Then test it. Their method is simple and I like it: shoulder the rifle ten times at 1x and you should get a full picture at least eight times. At full power, aim for six out of ten. If you are missing that, slide the scope forward or back in the mount before you blame the glass.

What Are the Downsides?

Let’s give the red dot its due. Vortex itself says an LPVO adds more weight to the rifle than a red dot or holographic sight and needs a precision mount that eats rail space. It is also slower than a dot if you ever forget it is cranked to 6x and have to shoot something close (turn it back down when you walk away from the bench, trust me).

If all your shooting is inside 50 yards, a dot is lighter, cheaper and faster. Our complete guide to red dot sights covers that side, and if you are stuck between a dot and an EOTech style sight, read holographic sight vs. red dot first.

How Should You Zero an LPVO Scope?

Zero it at 100 yards with the power turned all the way up, since that is where you can see your group best. Once it is zeroed, plug your load into our free ballistic calculator to see exactly where it lands at 200, 300 and beyond, and match that against the holdover marks in your reticle. If you are still deciding what the rifle under the scope should shoot, Popular Ammo has a good breakdown of 300 Blackout vs 5.56.

Frequently Asked Questions

What does LPVO stand for?

Low-power variable optic. “Low power” because the top end is usually 4x to 10x, which is low next to a long-range scope, and “variable” because you can dial the magnification.

How much eye relief does an LPVO have?

Typically about 3.5 to 4 inches, according to MyGunDeal’s eye box guide. The number on the box matters less than the eye box, so test it on your rifle.

Is an LPVO good for deer hunting?

Yes, especially in thick cover where shots can be close and far on the same morning. A 1-6x reaches most whitetail shots and still lets you shoot fast at 1x when a buck busts out of the brush.

Can an LPVO replace a red dot?

On a rifle, yes. At true 1x it works like a dot with a bigger, heavier package. On a pistol, no, that is still red dot territory.

Take my advice: buy a good 1-6x LPVO scope, put it in a mount that fits your face, and run it on 1x until you forget it can zoom. That is when it starts earning its money.
