10 Best AR optics 2025 in the United States

The SIG SAUER Tango-MSR LPVO 1-6X24mm riflescope stands out with its versatile 1-6x magnification, making it suitable for both close and mid-range shooting. The illuminated MSR BDC-6 reticle with 11 brightness settings ensures clarity and precision in various lighting conditions. The 24mm objective lens, combined with low dispersion glass, provides excellent light transmission and optical clarity, enhancing target acquisition.

Its second focal plane design keeps the reticle size constant across all magnifications. Durability is a strong point, with the scope being waterproof, fog-proof, and shockproof, thanks to nitrogen purging and a robust aluminum build. The factory-installed flip-back lens covers and included cantilever mount add to its convenience and protection.

However, the scope's weight of 2.29 pounds might be a bit heavy for users looking for a lightweight option. Adjustment turrets are precise. This riflescope is an excellent choice for tactical hunters or shooters needing a reliable and rugged optic, but users prioritizing weight may want to consider lighter alternatives.

The Vortex Crossfire II Dead Hold BDC 3-9x40 riflescope offers a solid magnification range from 3x to 9x, which works well for many shooting scenarios, from close to medium distances. Its Dead Hold BDC reticle helps hunters estimate holdover without complicated calculations, simplifying shots at varying ranges. The 40mm objective lens provides bright and clear views thanks to fully multi-coated lenses, enhancing visibility in different lighting conditions.

Eye relief is 3.8 inches, which is good enough for quick target acquisition and helps protect your eye from recoil, although some users might prefer a bit more space for comfort. Constructed from aircraft-grade aluminum, this scope is very durable, shockproof, waterproof, and fogproof, making it reliable for outdoor use in tough environments. The adjustment turrets are precise and easy to use, allowing quick zeroing and hold adjustments.

This model does not support night vision, so it’s not ideal if you plan for low-light or nocturnal shooting. Also, while the eye relief is decent, those using higher caliber rifles may want to verify its comfort for their specific setup. Backed by a lifetime warranty, the Crossfire II is a trustworthy choice for hunters and shooters seeking a dependable, versatile scope without breaking the bank.

The Trijicon ACOG 4 x 32 Scope USMC Rifle Combat Optic is a robust and highly reliable option for users seeking an ar-optic. It features a 4x magnification that is quite sufficient for medium-range shooting, and its 32mm objective lens ensures a clear and bright image. The scope's reticle is illuminated through a tritium/fiber optic system that adjusts automatically based on the lighting conditions, eliminating the need for batteries, which is a significant advantage for prolonged use in various environments.

The rugged aluminum-alloy housing adds to its durability, making it almost indestructible and ideal for tough conditions. Additionally, the Bindon Aiming Concept allows for the use of both eyes open, which enhances situational awareness and ease of targeting in close-quarter scenarios. The bullet drop compensating and ranging reticles are designed specifically for the M16A4 weapon system and can adjust for ranges up to 800 meters, catering to long-distance accuracy requirements.

However, the eye relief of 1.5 inches is relatively short, which might be uncomfortable for some users, especially those who wear glasses. Moreover, at 2 pounds, the scope is a bit on the heavier side, which could affect the balance of the rifle. Despite this, the ACOG's combat-proven track record and high customer ratings reflect its performance and reliability. This optic is particularly well-suited for serious shooters, hunters, and military personnel who need a durable and dependable sighting system.
