9 Best Tactical Rifle Scope For M 4 2026 in the United States

The SIG SAUER Tango-MSR LPVO 1-6X24mm is a tactical rifle scope designed for M-4 platforms, offering several strengths that may appeal to hunting and tactical shooting enthusiasts. With a magnification range of 1x to 6x, it provides flexibility for both close and mid-range targeting. The 24mm objective lens, coupled with low dispersion glass, ensures excellent light transmission and optical clarity, making it easier to spot targets in various lighting conditions.

The illuminated MSR BDC-6 reticle, featuring 11 brightness levels, is a useful addition for enhanced visibility in different environments. Additionally, the scope is waterproof and fog-proof, thanks to its nitrogen-purged internals and sealed exterior, ensuring reliability in adverse weather conditions. The included flip-back lens covers and cantilever mount enhance its practicality and ease of use.

The second focal plane design means the reticle size remains constant, which might be preferred by some users but may not be ideal for those who require ranging capabilities at different magnifications. Weighing 2.29 pounds, the scope is relatively lightweight, but this might still be a consideration for users who prioritize a lightweight setup. The build quality, with its rugged aluminum construction, promises durability. However, the lack of night vision compatibility could be a limitation for users looking for more advanced features. The SIG SAUER Tango-MSR LPVO is a solid choice for those seeking a reliable, clear, and versatile tactical rifle scope for an M-4, especially in hunting and tactical scenarios.

The Trijicon ACOG 4x32 Scope USMC Rifle Combat Optic for A4 is a well-regarded tactical rifle scope, particularly suited for use with an M-4. One of its standout features is the battery-free illumination system, which uses tritium and fiber optics to automatically adjust the reticle brightness based on ambient light. This ensures consistent visibility without the need for batteries, a significant advantage in the field. Additionally, its robust aluminum-alloy housing makes it highly durable and combat-ready, aligning well with its extensive use in military operations.

The scope also allows for bullet drop compensation up to 800 meters, which is beneficial for long-range shooting accuracy. The 'both eyes open' design can be incredibly useful for quick target acquisition in close-quarter combat situations. However, the eye relief is relatively short at 1.5 inches, which might not be ideal for all users and could reduce comfort during extended use.

Weighing in at 2 pounds, it's relatively lightweight, adding to its ease of handling. This scope is versatile, being compatible with various calibers such as .223, .308, and others, making it a good fit for multiple firearm setups. In summary, the Trijicon ACOG 4x32 is a rugged, reliable, and highly functional option for anyone in need of a tactical scope for their M-4, with minor drawbacks that might affect only specific users.

The Trijicon TR23 AccuPoint 5-20x50 is a solid tactical scope for M4 rifles, especially useful for shooters who need both medium and higher magnification options. With a zoom range from 5x to 20x, it offers flexibility for targets at varying distances. The large 50mm objective lens helps bring in plenty of light, improving clarity in low-light conditions. It features a MIL-Dot crosshair reticle illuminated with a green dot that adjusts automatically to lighting thanks to fiber optic and tritium technology—this means you don’t need batteries and can rely on it even at night. Eye relief is generous at about 4 inches, which is comfortable and safe for most shooters. The field of view at 3.7 degrees is typical for this magnification range, enough for precise long-range aiming but narrower than lower-powered scopes.

The scope is ruggedly built with aircraft-grade aluminum and is waterproof up to 10 feet, making it well-suited for outdoor use in tough conditions. The reticle is in the second focal plane, so its size doesn’t change with zoom, which some users prefer for consistent aiming points but might be less ideal if you need ranging at different magnifications. At 1.8 pounds, it’s reasonably lightweight but might add noticeable weight to smaller rifles. This scope is a reliable, battery-free illuminated option for tactical shooters or hunters needing a durable, high-quality optic for medium to long-range engagements, though it may not include some advanced turret features that competitive shooters look for.
