The Leupold VX-5HD 3-15x44 Riflescope is a high-quality option for those seeking a tactical rifle scope for an M-4. It offers a versatile magnification range from 3x to 15x, making it suitable for both close and long-range engagements. The 44mm objective lens provides a bright and clear image, even in low light conditions. The illuminated FireDot Duplex Reticle is a standout feature, ensuring quick target acquisition and better visibility in various lighting conditions. The CDS-ZL2 system is particularly useful, allowing for precise elevation adjustments and preventing accidental changes with its ZeroLock mechanism.

Additionally, the scope is waterproof, fogproof, and shockproof, ensuring durability and reliability in harsh environments. The hydrophobic Guard-ion lens coating is a practical addition, as it repels water and dirt, maintaining a clear view with minimal maintenance.

One of the notable strengths is the side focus parallax adjustment, which allows for quick and easy focusing from different shooting positions. Another plus is that this riflescope is designed, machined, and assembled in the USA, backed by Leupold’s full lifetime guarantee. Potential drawbacks include its weight of 1 pound, which might be slightly heavy for some users. Additionally, the price point may be a consideration for budget-conscious buyers. The Leupold VX-5HD 3-15x44 Riflescope is an excellent choice for those needing a reliable, feature-rich tactical scope for their M-4, offering a good blend of performance, durability, and advanced features.

The Leupold Mark 4HD 8-32x56 (34mm) M1C3 Side Focus FFP PR2-MOA Riflescope is a high-caliber choice for those in need of a tactical rifle scope for an M4. With a powerful 8-32x magnification and a large 56mm objective lens, it provides excellent light transmission and a clear, sharp image, even in challenging lighting conditions. The first focal plane (FFP) reticle is particularly beneficial for shooters who need consistent range estimation across all magnification levels.

This scope is built to last, being waterproof, fogproof, and shockproof, and backed by Leupold’s reputable customer care. It is designed, machined, and assembled in the USA, emphasizing quality and reliability. The professional-grade optical system with industry-leading glare reduction ensures clarity and resolution suited for professional guides or shooters in the field. However, it's important to note that it does not come with night vision capabilities, which could be a limitation for those needing to operate in low-light environments.

Additionally, its relatively high price point may be a consideration for budget-conscious buyers. With a mounting type suited for rail mounts and a solid aluminum construction, this scope is durable and designed for rigorous use. This riflescope is ideal for hunting and professional shooting where high magnification and clarity are critical, but may not be the best fit for those requiring night vision or on a tight budget.

The Nightforce NX8 1-8x24 F1 scope is designed to be a versatile, lightweight, and compact option for M4 users who want quality optics without adding bulk. Its magnification range from 1x up to 8x allows quick target acquisition at close distances with the 1x setting, similar to a red-dot sight, while providing enough zoom for mid-range precision. The 30mm objective lens is a good balance—it’s not very large but still lets in enough light for clear images, especially in daylight. The FC-Mil reticle is in the first focal plane, meaning it stays accurate at all magnification levels, which is great for shooters who need precise hold points as their targets move further away. The daylight-visible center red dot helps speed up aiming in bright conditions. Eye relief and field of view are solid, with a 13.2-foot view at 100 yards allowing good situational awareness without tunnel vision.

One standout feature is the ZeroStop elevation turret, which lets you quickly return to your zero setting after adjustments, a handy tool for tactical or competitive shooters dialing for longer shots. Turrets offer fine, repeatable adjustments in 0.2 Mil-radian increments, or roughly half a minute of angle, giving precise control. At only 8.75 inches long and weighing just over a pound, it won’t weigh down your rifle or interfere with handling. The 30mm tube adds durability without extra heft. This scope is built tough with quality materials to withstand rough use.

The relatively small 24mm objective lens may not perform as well in low-light conditions compared to larger lenses. Also, while the reticle offers versatility, beginners might find the Mil-based measurements a bit complex without practice. The price point is typically higher given the brand’s reputation, which might be a consideration for budget-conscious buyers. This scope suits M4 owners who want a reliable, quick-adjusting tactical scope effective for both close and mid-range shooting, especially in daylight or moderately low light. It blends rugged construction with smart features, though those new to reticle math may need some time to fully use its potential.
