Best AR-15 Scope: 4 LPVOs Worth Mounting on Your Rifle

The best AR-15 scope for most shooters is a 1-6×24 low power variable optic, or LPVO. On 1x it handles like a red dot for close, fast shots. Turn it up to 6x and you can identify targets, read wind on steel and hold for drop farther out. Our four picks: the SIG SAUER Tango-MSR 1-6×24 if you want the scope and mount in one box, the Primary Arms SLx 1-6×24 Gen IV for a lot of reticle on a tight budget, the Trijicon Credo HX 1-6×24 for a .223 hunting rifle, and the EOTECH Vudu 1-10×28 FFP when you want more magnification without giving up 1x.

We picked these from the riflescopes Western Sport carries and checked every number below against the maker’s own spec sheet. Here is how they stack up and who each one fits.

How We Picked the Best AR-15 Scope

An AR-15 in 5.56 or .223 is a carbine at heart. Most of the shooting happens inside a few hundred yards, a lot of it inside 100. That is why the LPVO took over. Vortex puts it well in its guide to picking the perfect optic for your AR: an LPVO “can hang with the red dots when it comes to tight spaces” and then reach out next to bigger, higher-power scopes.

We looked at four things on every scope:

• True 1x on the low end. If the bottom setting is not 1x, the scope is slower up close.
• Illumination you can see in daylight. A lit center dot is what makes 1x feel like a red dot.
• Eye relief and weight. AR stocks put your eye in a fixed spot. A forgiving eyebox and a scope under about 22 ounces keep the rifle handy.
• Reticle that matches the job. A BDC built for .223 or 5.56 saves you math. A mil or MOA grid gives you more control if you dial or hold precisely.

Specs from SIG SAUER, Primary Arms, Trijicon and EOTECH product pages, checked November 8, 2026.

1. Best Scope and Mount Package: SIG SAUER Tango-MSR 1-6×24

The SIG SAUER Tango-MSR 1-6×24 with the MSR-BDC6 reticle is an easy first LPVO because it shows up ready to go on the rifle. SIG ships it with the ALPHA-MSR one-piece aluminum cantilever mount and lay-flat flip caps, so you are not hunting for rings that fit a 30mm tube.

It is a second focal plane scope with an illuminated BDC6 reticle and 11 brightness settings, run off one CR2032 battery. SIG lists eye relief at 3.93 inches on 1x and 3.74 inches on 6x, a 124.8 foot field of view at 100 yards on 1x, 100 MOA of total elevation travel and a weight of 18.5 ounces. That is a light, simple setup for a range carbine, a truck gun or a hog rifle.

Who it fits: anyone who wants one purchase, one box and a scope on the rifle the same afternoon.

2. Best Budget LPVO: Primary Arms SLx 1-6×24 Gen IV

The Primary Arms SLx 1-6×24 SFP Gen IV with the ACSS NOVA reticle packs a lot of reticle into a budget scope. The NOVA uses a fiber wire that Primary Arms calls Red Dot Bright illumination, with 11 settings. The reticle also carries range estimation marks, mil holds and leads for moving targets.

Primary Arms lists 4 inches of eye relief, 0.1 mil clicks, 120 MOA of total adjustment, a 120 foot field of view at 100 yards on 1x, a length of 10.4 inches and 17.9 ounces with the battery in. It also has a built-in magnification throw lever, so you can spin from 1x to 6x without adding a part.

Who it fits: the shooter building a first AR who wants a real LPVO without spending the rest of the build budget on glass. Plan on adding a 30mm LPVO mount, since one is not in the box.

3. Best for a .223 Hunting Rifle: Trijicon Credo HX 1-6×24

If your AR does double duty on hogs, coyotes and deer where your state allows the cartridge, look at the Trijicon Credo HX 1-6×24 with the red BDC Hunter Holds .223 reticle. The holds are laid out for .223 loads, so you get aiming points for longer shots without dialing.

Trijicon’s Credo HX 1-6×24 page and spec sheet list a second focal plane reticle in a 30mm tube, low capped adjusters with 1/4 MOA clicks and 100 MOA of travel, eye relief of 3.5 to 3.9 inches and a field of view of 113.4 feet at 100 yards on 1x. The LED runs on one CR2032. Trijicon rates the red illumination at 68 hours on a mid-high setting, so carry a spare battery in your pack.

The low capped turrets are a quiet plus on a hunting rifle. Once you zero it, the caps keep a brush or a sling from bumping your adjustments.

Who it fits: the hunter who wants a clean, simple reticle tuned for the cartridge in the rifle.

4. Best for More Reach: EOTECH Vudu 1-10×28 FFP

When 6x is not enough, the EOTECH Vudu 1-10×28 FFP with the SR-4 MOA reticle stretches the top end to 10x and keeps a true 1x on the bottom. EOTECH describes the SR-4 as a duplex style reticle graduated in MOA with a 1 MOA center aiming dot, which keeps the picture clean while still giving you hash marks for holdover and wind.

Because it is first focal plane, the reticle grows and shrinks with magnification and the hash marks read true at every power. EOTECH’s Vudu 1-10×28 page lists a 34mm tube, a field of view of 116.6 feet on 1x and 11.7 feet on 10x at 100 yards, a length of 10.63 inches and a weight of 21.3 ounces. That is the heaviest scope here, and the 34mm tube needs 34mm rings or a 34mm mount.

Who it fits: the shooter running an 18 or 20 inch AR, a designated marksman style build, or anyone who stretches the rifle past what 6x makes comfortable. If you like the brand, our EOTECH buyer’s guide walks through the rest of the line.

First or Second Focal Plane on an AR-15?

This question comes up with every LPVO. Vortex sums it up: “First focal plane optics ensure the features on your reticle are usable at any magnification. A second focal plane reticle’s features will be accurate only at a particular magnification, usually the highest.”

On a 1-6x, second focal plane is the easy choice for most people. The reticle stays the same size, so it is bold and easy to see on 1x, and the holds usually read true on 6x, the power where you will use them. First focal plane earns its keep on 8x and 10x scopes like the Vudu, where you will hold and range at several powers.

Mounting an LPVO on an AR-15

An AR-15 needs a cantilever mount that sets the scope forward and high enough to line up with your eye when your cheek is on the stock. Match the mount to the tube: 30mm for the SIG, Primary Arms and Trijicon, 34mm for the EOTECH. The SIG already includes its mount. For the others, browse our scope mounts and pick a one-piece LPVO mount in the right tube size.

Torque the rings to the mount maker’s spec, set the scope so you get a full picture with your normal cheek weld, then zero it. Our step by step guide to zeroing an AR-15 at 50 and 100 yards covers the range day. If you want the bolt-gun version, read how to sight in a rifle scope.

LPVO or Red Dot?

If your AR is strictly a home defense rifle inside the house, a red dot is lighter, simpler and has unlimited eye relief. Our roundup of the best red dot sights for the AR-15 covers that side, and our LPVO vs red dot comparison puts speed, weight and setup cost side by side. Already own a dot? A red dot magnifier adds 3x or 5x behind it. If the same rifle goes to the ranch, the lease and the range, an LPVO does all of it with one optic. That is why we think a 1-6x is the best all-around scope for an AR-15.
