10 Best AR-15 Optic & Sight Options Right Now

XS Sights XTI2 DXS Ember Standard Dot

The AR-15 is easily America’s most popular rifle. Upwards of 20 million of AR-pattern rifles have been sold in this country, and they’re widely used for defense, competition and hunting. Most of these guns come with railed, flattop receivers, which makes it easy to mount a variety of optics. And when we say variety, well, there are now so many optics and sights specifically meant for the AR-15 rifle that it can be overwhelming. 

Here are some of our picks for options worth checking out. As usual, the prices are suggested retail and will vary widely. When they do, they’re typically lower than what is given here.

XS Sights XTI2 DXS Ember Standard Dot

Backup iron sights are considered vital by most AR shooters, and angled sights like these from XS allow you to use the iron sights without having to remove your optic—just cant the rifle and the open-sight system is immediately available. The XTI2 DXS (shown above mounted closer together than you would normally set them up, just for the photo) features a highly visible front orange dot that absorbs ambient light so it glows in low light or in shadow. The rear sight is drift adjustable and features a white stripe for fast acquisition and alignment. The bases are 6061 T6 aluminum and the sights themselves are CNC-machined steel. Will fit on all optics-ready ARs. $138, XSsights.com

SIG Sauer Romeo 4T

If you’re looking for a solid “head for the hills” choice, the Romeo 4T is right up your alley thanks to a dual battery/solar power source that promises a run time in excess of 100,000 hours. The non-magnifying sight is constructed of a durable, lightweight 7075 aluminum main housing, and it comes with a 1.4-inch riser mount and a co-witness spacers. It comes with SIG’s circle dot reticle, and you can toggle the reticle to get four different versions of it. The sight offers 100 m.o.a. of both windage and elevation adjustment, all in a unit less than 3.5 inches long and weighing just 7.6 ounces. Waterproof to 20 meters, fogproof. $750, SIGsauer.com

Nightforce NX8 1-8x24 F1

Compact, lightweight scopes like this one from Nightforce are really versatile, and this one is even more so thanks to its combination of a daylight-visible red dot and a first-focal-plane reticle. Use the red dot for fast, close-up work or the reticle—available in 0.2 mil or 1/2 m.o.a. adjustments. The elevation turret incorporates a zero stop in case you have to dial up for a long shot and then go back down to your zero without worrying about losing count. Power adjustments are quick and easy thanks to a bult-in throw lever. The scope is just 8.75 inches long and weighs a mere 17 ounces. $1,750, NightforceOptics.com

Trijicon MRO HD

The new Miniature Rifle Optic HD has a re-engineered objective lens for a more refined two m.o.a. dot and is optimized for use with the company’s 3X magnifier (shown). The new design eliminates the tunnel effect common to sights of this type. An ambidextrous control selects not only brightness level but also allows the shooter to pick the dot reticle only or a dot surrounded by a 68 m.o.a. segmented circle. There are eight brightness settings: Two are night-vision-compatible; five are daylight; and there’s a super-bright setting for use with weapon lights or when conditions are exceedingly bright. Built of 7075-T6 aluminum, it’s waterproof to 100 feet, and chemical and corrosion resistant. Starts at $919, trijicon.com

Vortex AMG UH-1 Gen II Holo Sight

Probably the biggest selling point for the AMG UH-1 is its night-vision capability. This holographic sight is designed for close-quarter use, and it delivers four night-vision-compatible settings and a dedicated night-vision button. It has a large viewing window, and the sight’s EBR-CQB reticle is fast to acquire. Lenses are fully multicoated, and the design virtually eliminates stray light emissions so there’s no forward signature. The sight weighs is 11 ounces and is just under four inches long. It offers 100 m.o.a. of adjustment and runs off a CR123A battery. Shockproof, waterproof and fogproof. $800, VortexOptics.com

Leupold VX-Freedom AR 6-18x40mm

Maybe defensive shooting or running around at a 3 Gun match isn’t your cup of tea, and you want an optic that will reach out on the varmint fields without spending a fortune. This 30mm tube scope offers a top end of 18X and features Leupold’s TMR (VX-Freedom) reticle, a mil dot design using hash marks instead of dots. It’s not caliber specific, so it’ll work for any hunting caliber once you figure out what the hash marks, which are spaced a half mil apart, mean for your trajectory at a given magnification. Side-focus parallax adjustment sets you up for precision at any range, and the company’s Twilight Management System can extend your shooting day. Waterproof and fogproof. $780, leupold.com
