Finding the best AR 1 4x scope can dramatically improve your shooting versatility, whether you’re engaging targets at close range or reaching out to medium distances with precision. The 1-4x magnification range has become the gold standard for AR-15 platform rifles because it offers the perfect balance between speed and accuracy. At 1x, you can shoot with both eyes open for lightning-fast target acquisition in close quarters, then dial up to 4x when you need to make precise shots at 200 to 300 yards. This versatility makes 1-4x scopes incredibly popular for three gun competition, tactical applications, hunting, and general recreational shooting.
The AR-15 platform itself deserves recognition as one of the most adaptable firearms ever designed. Originally developed by Eugene Stoner in the late 1950s, the AR-15’s modular design and lightweight construction revolutionized modern rifles. The direct impingement gas system keeps the rifle lightweight while the flat-top receiver with Picatinny rail makes mounting optics straightforward and repeatable. When you pair an AR-15 with a quality 1-4x scope, you create a system capable of handling virtually any shooting scenario you might encounter, from close range defensive situations to longer range precision work.
What makes a great 1-4x scope for the AR platform goes beyond just magnification range. You need true 1x at the low end with no fish-eye distortion or tunnel vision, allowing for both eyes open shooting just like a red dot sight. The glass quality matters tremendously because you’ll be using this scope in varying light conditions, and superior coatings make the difference between identifying your target clearly or squinting at a murky image. Eye relief is important for comfortable shooting, especially during rapid fire when consistent cheek weld matters. The reticle design should provide both a fast acquisition reference at 1x and precise aiming points at higher magnifications. Durability is non-negotiable since the AR-15’s direct impingement system creates significant vibration and heat that can punish lesser optics over time.
The scopes we’ve selected represent the best options currently available across different price points and feature sets. Each has been chosen for its ability to handle the unique demands of the AR-15 platform while delivering the versatility that makes 1-4x scopes so popular among serious shooters.

1) Vortex Strike Eagle 1-6×24 (Best AR 1 4x Scope Overall)
The Vortex Strike Eagle 1-6×24 earns our top spot as the best AR 1 4x scope overall, even though it technically offers a bit more magnification at 6x instead of 4x. This extra magnification makes it even more versatile without sacrificing any of the close range speed you need from a low power variable optic. The Strike Eagle delivers true 1x magnification at the low end, meaning you can shoot with both eyes open just like a red dot sight, with zero tunnel vision or distortion that plagues cheaper scopes claiming to be 1x. This feature alone makes the Strike Eagle worth considering because that true 1x capability is what transforms a good scope into a great close quarters optic.
The AR-BDC3 reticle is specifically designed for the 5.56 NATO cartridge and features a center illuminated dot surrounded by a circle, with hash marks below for bullet drop compensation out to 600 yards. The reticle is glass-etched, which means it’s visible even if your battery dies, though you’ll definitely want to use the illumination in most situations. Vortex equipped this scope with 11 illumination levels, and the top settings are genuinely daylight bright, visible even in full Arizona sun. The second focal plane placement keeps the reticle size constant, making it faster to use at lower magnifications.
Optically, the Strike Eagle punches well above its mid-range price point. The fully multi-coated lenses deliver excellent light transmission and image clarity, with good color accuracy and contrast that makes target identification easier. The 24mm objective lens might seem small compared to traditional hunting scopes, but it’s perfectly sized for a 1-6x optic and keeps the overall package compact and lightweight. At 17.6 ounces, this scope won’t unbalance your AR-15, and the overall length of 10.5 inches fits perfectly on a standard flat-top receiver with room for backup iron sights if desired.
The construction quality reflects Vortex’s reputation for building tough optics. The single piece 30mm tube is machined from aircraft-grade aluminum and has been hard-anodized for scratch resistance. The scope is fully waterproof and fog proof thanks to O-ring seals and argon purging. Eye relief is a generous 3.5 inches at 1x extending to 3.7 inches at 6x, which provides comfortable shooting even during rapid fire. The included throw lever attaches to the magnification ring, allowing you to change magnification with a simple flick of your support hand thumb without breaking your shooting grip. For AR-15 shooters who need a versatile optic that handles everything from close quarters to medium range precision, the Strike Eagle delivers exceptional performance backed by Vortex’s legendary VIP lifetime warranty.

Check Price on Amazon2) Primary Arms SLx 1-6×24 Gen III (Best Advanced Reticle AR 1 4x Scope)
The Primary Arms SLx 1-6×24 Gen III takes reticle innovation to another level with its ACSS (Advanced Combined Sighting System) that transforms how you engage targets at any distance. While it offers 6x magnification rather than stopping at 4x, this extra power only enhances its versatility on the AR platform. The ACSS reticle is unlike anything you’ll find from traditional optics manufacturers, featuring an illuminated chevron center point surrounded by a large horseshoe that catches your eye instantly at 1x for incredibly fast target acquisition. Below the center chevron, you’ll find ranging brackets and bullet drop compensation marks calibrated for 5.56 NATO, along with wind hold references that take the guesswork out of shooting in breezy conditions.
What makes the ACSS reticle truly special is how it guides your eye to the target. At close range with the magnification set to 1x, that large horseshoe acts like a giant funnel directing your focus to the precise chevron aiming point in the center. You can engage targets with both eyes open at speeds approaching a red dot sight, but with the added capability of precise holdovers when you dial up the magnification. The ranging brackets allow you to estimate target distance by measuring against average human shoulder width, which is incredibly useful in tactical or competitive shooting scenarios. Primary Arms provides free ballistic calculators on their website where you can input your specific load data to determine exactly what distance each hash mark represents.
The optical performance of the Gen III SLx represents a significant improvement over earlier generations. Primary Arms upgraded to fully multi-coated lenses with an advanced coating process that delivers better light transmission and sharper images than previous versions. The glass is sourced from Japan, which generally means higher quality than Chinese glass found in many budget optics. Colors are accurate and vivid, contrast is excellent, and the scope performs well even in low light conditions. The illumination system offers multiple brightness levels including several night vision compatible settings, and the top brightness settings are truly daylight visible.
Construction quality is robust with a 30mm single piece tube design that’s been hard anodized for durability. The scope is nitrogen purged and fully sealed with O-rings for reliable waterproofing and fog proofing. At 17.4 ounces, the weight is similar to the Vortex Strike Eagle, keeping your AR-15 well balanced. Eye relief runs from 3.5 to 4 inches depending on magnification, which is comfortable for rapid fire work. The capped turrets are finger adjustable in half MOA increments and track reliably. Primary Arms includes a throw lever that makes magnification changes quick and positive. This scope excels for shooters who want maximum capability from their reticle and don’t mind a slightly steeper learning curve to unlock all the ACSS system’s features.

Check Price on Amazon3) Burris RT-6 1-6×24 (Best Value AR 1 4x Scope)
The Burris RT-6 1-6×24 delivers premium features at a mid-tier price point, making it an outstanding value for AR-15 shooters who want serious performance without spending a fortune. Like our top two picks, the RT-6 offers 6x maximum magnification rather than stopping at 4x, giving you extra reach for precision work while maintaining true 1x capability at the low end for close range speed. Burris has been manufacturing optics in the United States since 1971, and while some of their production has moved overseas, the RT-6 benefits from decades of optical engineering experience. The result is a scope that competes admirably with options costing significantly more.
The Ballistic CQ reticle is specifically designed for modern sporting rifles and features an illuminated center dot with a circle surrounding it at 1x, creating fast target acquisition similar to a holographic sight. As you increase magnification, the hash marks below the center aiming point become visible and useful for bullet drop compensation. The reticle is second focal plane, keeping it a constant size regardless of magnification setting, which many shooters prefer for this type of optic. Burris offers five brightness settings for the illumination, and while it’s not quite as bright as the Vortex or Primary Arms at maximum setting, it’s adequate for most shooting conditions.
Optical quality is where the RT-6 really impresses for its price point. The fully multi-coated lenses deliver sharp, clear images with good color fidelity and contrast. Light transmission is solid, making this scope usable during early morning and late evening shooting sessions when game is most active. The 24mm objective keeps the scope compact and lightweight while still gathering enough light for practical use. The fast focus eyepiece allows quick adjustment to dial in perfect reticle clarity, and once set, it stays put. The eyebox is reasonably forgiving, making it easy to acquire your sight picture quickly without excessive head positioning.
The RT-6’s construction features a 30mm main tube machined from a single piece of aluminum for strength and rigidity. The scope is nitrogen purged to prevent internal fogging and is fully waterproof and shockproof to handle the rigors of field use. At 16.5 ounces, it’s actually the lightest scope in our top three, which your trigger arm will appreciate during extended shooting sessions. Eye relief measures 3.5 to 4 inches, providing comfortable shooting position throughout the magnification range. The low profile turrets are capped to prevent accidental adjustment and click in half MOA increments. Burris backs the RT-6 with their Forever Warranty that covers the scope for life regardless of who owns it. For shooters seeking maximum value, the RT-6 delivers features and performance that belie its affordable price tag.

Check Price on Amazon4) Leupold VX-Freedom 1.5-4×20 (Best Premium AR 1 4x Scope)
The Leupold VX-Freedom 1.5-4×20 represents American-made quality and takes a different approach than the other scopes on this list by offering true 1.5-4x magnification rather than extending to 6x. This makes it a more traditional choice that some shooters prefer, particularly hunters who value the simplicity of a lower magnification range and don’t need the extra power for their typical shooting distances. Leupold has been crafting riflescopes in Beaverton, Oregon since 1947, and their reputation for building bombproof optics that hold zero in the harshest conditions is legendary. When you mount a Leupold on your AR-15, you’re getting over 75 years of optical engineering expertise.
The VX-Freedom features Leupold’s Twilight Light Management System, a combination of lens coatings and design elements that maximize usable light during dawn and dusk when many animals are most active. This system can extend your effective shooting time by up to 30 minutes in low light conditions, which can make the difference between success and disappointment on a hunt. The fully multi-coated lenses deliver the crystal clear images and color accuracy that Leupold is famous for, with contrast and sharpness that make target identification easy even at distance. The Duplex reticle is simple and uncluttered, featuring thick outer posts that guide your eye to center and fine crosshairs for precise aiming.
What really sets the VX-Freedom apart is the eye relief, which measures an incredibly generous 4.2 inches. This is significantly longer than most 1-4x scopes and provides a margin of comfort that’s appreciated during rapid fire or when shooting from awkward positions. The extended eye relief also makes this scope perfect for eyeglass wearers who need extra distance between their eye and the ocular lens. The eyebox is forgiving, allowing you to acquire your sight picture quickly without perfect head alignment. The fast focus eyepiece adjusts easily and stays put once you’ve dialed in the perfect reticle sharpness for your eyes.
Construction quality is where Leupold really justifies its premium pricing. The main tube is machined from a single billet of aircraft-grade aluminum, creating a stronger structure than multi-piece designs. The scope is sealed with a second generation argon-krypton waterproofing system that’s more effective than standard nitrogen or argon purging alone. At just 9.7 ounces, the VX-Freedom 1.5-4×20 is remarkably lightweight and won’t unbalance even the most carefully built AR-15. The 1 inch tube diameter is traditional rather than the 30mm tubes found on our other picks, but it’s perfectly adequate for a 4x scope and keeps the weight down. Leupold’s lifetime guarantee ensures this scope will serve you reliably for decades, and their customer service is genuinely excellent if you ever need it. For shooters who value premium American-made quality and proven reliability, the VX-Freedom delivers performance that’s worth the investment.

When making your final decision, consider how you’ll primarily use your AR-15. Three gun competitors might prioritize the fastest reticle and most daylight bright illumination. Hunters will value low light optical performance and practical holdover marks for quick shots at game. Home defense oriented shooters need bombproof reliability and true 1x capability above all else. Match your scope choice to your mission, invest in quality rings or mounts to protect your investment, and you’ll have a setup capable of handling anything you throw at it. The AR-15 platform deserves quality optics that match its capabilities, and these five scopes deliver exactly that.
