10 Best sniper AR 15 scopes 2025 in the United States

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 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.

The Leupold VX-5HD 3-15x44 riflescope is a solid choice for AR-15 shooters looking for versatile magnification and reliable performance. Its 3-15x magnification range offers flexibility for both close and longer-range shots, while the 44mm objective lens provides good light gathering for clear images in various conditions. The illuminated FireDot Duplex reticle aids in quick target acquisition and low-light visibility. One standout feature is the CDS-ZL2 turret system, allowing precise elevation adjustments with a push-button lock to prevent accidental changes, which is especially useful for shooters who need consistent zeroing. The side focus parallax adjustment helps maintain a sharp sight picture, reducing eye strain and improving accuracy. Eye relief is comfortable, thanks to the 30mm tube size, accommodating different shooting positions. Leupold's Guard-ion lens coating resists dirt and water, enhancing maintenance ease and clarity. Constructed from durable aluminum, this scope is waterproof, fogproof, and shockproof, making it dependable in tough field conditions.
