The Leupold VX-5HD 3-15x44 riflescope is a high-quality option for those seeking a versatile tactical scope for an M-4. It offers a broad magnification range from 3x to 15x, making it suitable for both close-quarters and long-distance engagements. The 44mm objective lens diameter ensures a bright and clear image, even in low-light conditions, which is enhanced by Leupold's high-definition lenses and Guard-ion hydrophobic coating to keep the lens clean from dirt and water.

The Fine Duplex reticle provides a simple, precise aiming point without clutter, which can be beneficial for quick target acquisition. Eye relief is critical for user comfort and safety, and this scope provides ample eye relief for most users. One standout feature is the CDS-ZL2 (Custom Dial System - ZeroLock 2), allowing precise and repeatable elevation adjustments with a locking mechanism to prevent accidental changes. This feature, along with the side focus parallax adjustment, makes it easy to achieve sharp focus from various shooting positions.

The scope is robustly built, being waterproof, fogproof, and shockproof, and it comes with Leupold's lifetime guarantee, offering peace of mind regarding durability and performance. On the downside, the scope is relatively heavy at 1.2 pounds, which might be a consideration for some users. Additionally, it does not include night vision capabilities, which could be a limitation for nocturnal operations. The Leupold VX-5HD 3-15x44 is an excellent, durable option for tactical use, offering impressive optics and reliable performance, but its weight and lack of night vision might be drawbacks for some users.

The Vortex Diamondback Tactical 6-24x50 is a solid choice for anyone looking to equip an M-4 style rifle with a reliable tactical scope. It offers a versatile magnification range from 6x to 24x, which allows for both medium and long-range targeting. The large 50mm objective lens gathers plenty of light, providing a bright and clear image even in lower light conditions. Its fully multi-coated lenses and extra-low dispersion glass contribute to crisp and sharp visuals, which is important when precision matters.

The first focal plane reticle (EBR-2C MOA) is a standout feature, meaning the reticle stays correctly scaled through all zoom levels—helpful for accurate holdovers and range estimation at different distances. Eye relief and field of view are sufficient for comfort and situational awareness, with a 4.5-foot field of view that balances detail and coverage. Turrets are exposed and easy to adjust, paired with a side parallax knob, giving users the control needed for precise windage, elevation, and focus adjustments during tactical or long-range shooting.

The scope’s 30mm one-piece aluminum tube is durable, shockproof, and sealed against water and fog, making it dependable in tough outdoor conditions. Weighing around 1.5 pounds, it’s moderately heavy but still manageable for most shooters. The included accessories like lens covers and a sunshade add value. The lifetime VIP warranty is a reassuring bonus. While excellent for tactical and hunting use, this scope does not support night vision, and some might find the weight a bit overkill for lightweight builds. Mounting options may require separate consideration depending on your rifle setup. This scope delivers strong optical quality, rugged construction, and user-friendly adjustments, making it well suited for tactical shooters and hunters who want precise, long-range capability without breaking the bank.

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.
