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 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 EOTECH Vudu 3.5-18x50mm is a versatile tactical rifle scope offering a wide magnification range suitable for both close and mid-to-long-range shooting, making it a good fit for an M-4 setup.

The first focal plane reticle (H59) adjusts in size with zoom, allowing for accurate holdovers and ranging across all magnifications.

Constructed from durable aluminum, the scope is water, shock, and fog resistant, ensuring reliability in tough field conditions. It weighs about 1 pound, which keeps the rifle setup lightweight and easy to handle. The turret adjustments are precise, supporting accurate windage and elevation changes. Although the scope does not support night vision, it comes with a limited lifetime warranty, providing added peace of mind.

This scope serves as an excellent option for shooters seeking a rugged, clear, and flexible optic for tactical or hunting applications with an M-4 rifle. Users requiring night vision compatibility or highly specific turret details might want to consider additional options.
