The Leupold Mark 5HD 3.6-18x44 M5C3 FFP PR2-MIL is a high-quality tactical rifle scope made with professional-grade optics. It offers a versatile magnification range from 3.6x to 18x, which is great for both close-quarters and longer-range shooting, making it well suited for the M-4 rifle platform. The 44mm objective lens size strikes a good balance between light gathering and size, helping deliver bright, clear images even in challenging lighting conditions.

This scope features a First Focal Plane (FFP) reticle, meaning the reticle scales with magnification, which is very useful for range estimation at any zoom level. The PR2-MIL reticle is designed with military and tactical users in mind, offering precise aiming points. The field of view at the lowest magnification is 28.3 feet per 100 yards, providing a decent viewing area to quickly acquire targets. The scope is rugged, waterproof, fogproof, and shockproof, built from aluminum with a durable Dark Earth finish, which is good for harsh environments.

One limitation is that it lacks night vision compatibility, so it might not suit users needing infrared features. Additionally, it is priced on the higher end and is somewhat larger in size, which may be more than casual shooters require. For serious shooters or professionals seeking clear optics, durability, and tactical-ready features, this scope remains an excellent choice.

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 Nightforce NX8 4-32x50mm scope is a strong choice for tactical use with an M-4 or similar rifles, thanks to its wide 4-32x magnification range. This means you can smoothly switch from close-up, fast-moving targets at 4x to very precise long-range shots at 32x, all with clear and sharp optics. The large 50mm objective lens helps gather plenty of light, improving visibility in low-light conditions. It features a rugged 30mm aluminum body that’s lightweight at 1.8 pounds, so it won’t add too much bulk to your setup. The MOAR reticle in the first focal plane is designed for accuracy, with clear markings for elevation and windage that help with precise aiming and range estimation. Eye relief is a comfortable 3.5 inches, which helps keep your eye safe from recoil while maintaining a good view. The field of view varies from 26.1 feet at 4x, giving a wide sight picture, down to 4.6 feet at 32x for detailed target focus.

Its ZeroStop turret system allows you to quickly return to your zeroed settings, and parallax adjustment from 11 yards to infinity ensures your target stays sharp at any distance. While the scope is packed with advanced features ideal for tactical and hunting scenarios, its relatively long length (13.4 inches) and higher price might be considerations for some users. Also, the scope is not designed for night vision compatibility, which could be a drawback if you need low-light tactical capabilities.

This scope delivers excellent versatility, precision, and durability that tactical shooters will appreciate, especially when engaging targets from close to very long ranges.
