10 Best AR scopes 2025 in the United States

The Vortex Optics Crossfire II 3-9x40 riflescope is a solid choice for AR scope users who want flexibility for mid-range shooting or hunting. Its 3-9x magnification covers close to moderate distances well, and the Dead-Hold BDC reticle helps estimate bullet drop without extra adjustments, which is handy for varying range shots. The 40mm objective lens size lets in enough light to provide bright and clear images, enhanced further by fully multi-coated lenses that reduce glare. A 34.1-foot field of view at 100 yards is fairly wide, making it easier to quickly spot and track targets. Eye relief of 3.8 inches is comfortable and safe for most shooters, reducing the chance of scope ‘kick’ impact on your face. Durability is strong with an aircraft-grade aluminum tube, plus waterproof and fogproof features, so it can handle tough outdoor conditions. The scope’s weight of 16 ounces keeps it light enough for comfortable handling.

One drawback might be that it lacks night vision capability, so it’s not ideal for low-light hunting. Also, while the reticle is great for holdover, it might not suit those wanting a simple crosshair or illuminated reticle option. This scope serves hunters and shooters who need reliable, clear optics with practical reticle features and rugged build quality, especially for daylight use.

The Vortex Optics Crossfire II 2-7x32 riflescope is well-suited for hunters and recreational shooters looking for a reliable sighting tool. With a magnification range of 2 to 7 times and a 32mm objective lens, it offers versatility for various shooting scenarios, particularly at differing distances. The Dead-Hold BDC reticle is especially beneficial for hunting, as it aids in estimating holdover, making it easier to hit targets without needing complicated calculations.

One of the standout features of the Crossfire II is its long eye relief of 3.9 inches and ultra-forgiving eye box, allowing users to quickly acquire a sight picture without straining. This is particularly advantageous for those who may wear glasses or prefer a more comfortable viewing experience. The fast focus eyepiece further enhances usability, ensuring a clear reticle.

In terms of construction, this riflescope is made from aircraft-grade aluminum, which provides durability and shock resistance. It's designed to withstand the elements with O-ring sealing and nitrogen purging, making it waterproof and fogproof. This durability is a critical strength for outdoor use. The magnification range might not satisfy those seeking extreme long-distance capabilities, and although it is great for close to medium range, more experienced shooters may prefer higher magnifications for precision shooting. The unlimited, unconditional lifetime warranty offered by Vortex adds value, giving peace of mind for those concerned about future issues. If you are looking for a reliable, versatile riflescope for hunting and general shooting, the Vortex Optics Crossfire II is a solid choice with great features, but it is best suited for mid-range use rather than extreme long-range applications.

The Leupold DeltaPoint Pro Red Dot Sight is designed primarily for shooters needing a reliable and clear aiming point across different firearms, including shotguns, handguns, and rifles. It features a 2.5 MOA illuminated red dot reticle that helps users quickly acquire targets, especially in low-light conditions. The scope has no magnification beyond 1x, making it ideal for close to mid-range shooting rather than long-distance precision. Its Twilight Max Light Management System improves image clarity by enhancing light transmission, reducing glare, and boosting contrast, which benefits target visibility without magnifying the image.

With a compact and lightweight aluminum body, this scope offers excellent durability. It is waterproof, fogproof, and shockproof, ensuring it can withstand harsh outdoor environments and rough handling. The integral mount simplifies installation and keeps the sight securely attached to your firearm. Eye relief is not explicitly stated but given the design, it should provide comfortable viewing without needing exact eye positioning.

A standout feature is the Motion Sensor Technology that preserves battery life by turning off the illuminated reticle after five minutes of inactivity and instantly reactivating it when movement is detected, saving power without compromising readiness. The scope does not support night vision, limiting its use in complete darkness. This sight is an excellent choice for hunters and tactical shooters who value quick target acquisition and durability over magnification. While it does not replace higher-magnification scopes needed for distant shots, it excels in close engagements where speed and clarity matter most. Backed by Leupold’s lifetime guarantee, it promises long-term reliability.
