Top 10 sniper AR 15 scopes Deals Right Now

The Trijicon 4x32mm ACOG is a solid choice for an AR-15 sniper scope, especially if you're looking for reliability in tough conditions. It offers a fixed 4x magnification with a 32mm objective lens, which provides a clear and bright image, good for mid-range shooting. One standout feature is its dual illumination system that doesn’t rely on batteries; it uses tritium and fiber optics to automatically adjust reticle brightness based on light conditions. This means you’ll have a clear green crosshair reticle in various lighting, including low light or night vision use, without worrying about battery life.

The scope is built tough with aircraft-grade aluminum and a special flat dark earth finish that resists wear and tear — making it highly durable for field use. It also supports the “both eyes open” shooting style, which can help with faster target acquisition in close-quarter situations. The package includes backup iron sights and a mounted red dot sight for versatility. Eye relief is comfortable at about 38mm, helping to prevent recoil injury and maintain a solid shooting position.

This scope is well-suited for shooters who want a rugged, easy-to-use optic with consistent illumination and decent mid-range precision. Shooters seeking extensive adjustment options for long-range precision may want to explore other scopes designed for that purpose.

The Vortex Crossfire II 3-9x40 is a solid choice for an AR-15 sniper scope, especially for hunters and shooters who want a reliable and clear sighting tool. Its 3-9x magnification range offers good flexibility, allowing you to zoom in enough for precision at medium distances without losing the wider view needed for quick target acquisition. The 40mm objective lens balances brightness and size well, providing a clear image without making the scope too bulky. The V-Brite illuminated V-Plex reticle brightens the center dot with battery power, making it easier to spot your target in low light conditions.

Eye relief is generous, and the scope's forgiving eye box makes quick target alignment easy without the need for perfect eye positioning. The fast-focus eyepiece simplifies reticle crispness adjustments, which is convenient when switching between targets. While the turrets are functional, they may not offer the most precise tactical adjustments for windage and elevation on the fly. Similarly, the lack of parallax adjustment means this scope is best suited for medium-range shooting rather than long-range precision.

Constructed from strong aircraft-grade aluminum, the scope is durable and capable of withstanding rough outdoor conditions. Its waterproof and fogproof design ensures reliability in adverse weather. At just 15 ounces, it adds minimal weight to your rifle. Additionally, the lifetime VIP warranty provides added assurance. This scope is an excellent, straightforward, and durable option for typical AR-15 shooting distances with good clarity and illumination.

The Trijicon ACOG 4 x 32 Scope USMC Rifle Combat Optic for A4 offers a robust and reliable option for those looking for a sniper scope for an AR-15. The scope features a fixed 4x magnification, which is ideal for medium-range engagements but may not suffice for very long-range shooting. The 32mm objective lens diameter provides a clear and bright image, although it may not be as large as some other sniper scopes in the market which can offer better light transmission in very low light conditions.

The scope's reticle, a red Chevron ranging reticle, is highly functional with bullet drop compensation out to 800 meters, making it suitable for precise aiming and long-range targeting. However, the 1.5 inches of eye relief is somewhat short, which could be a drawback for some users, especially those who use glasses or prefer a greater distance between their eye and the scope. One of the standout features is the battery-free illumination, which adjusts the brightness based on available light, ensuring that you are not left in the dark if batteries fail.

The rugged aluminum-alloy housing enhances durability and makes it nearly indestructible, a significant advantage for combat or rugged hunting environments. The Bindon Aiming Concept allows for both eyes open shooting, improving situational awareness. However, for those looking for more versatile magnification, the fixed 4x might be limiting. This scope is well-suited for military and tactical use, especially in medium-range scenarios, but may not be the best choice for users needing flexible magnification or longer eye relief.
