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 first focal plane (FFP) reticle is a big plus, as it stays accurate at all zoom levels, helping shooters estimate range without complicated adjustments. Eye relief is comfortable and consistent, which is important for quick target acquisition and safety.

The scope has a durable aluminum body with a matte finish that reduces glare and is built to handle rough environments—it’s waterproof, fogproof, and shockproof. Its turrets and adjustments are precise and easy to use, with side focus helping to keep targets sharp. However, the scope weighs around 1.8 pounds, which might feel a bit heavy for some users on lighter setups. Also, it doesn’t have night vision compatibility, so it’s best suited for daylight or low-light conditions without infrared assistance.

This scope is an excellent choice for serious shooters and professionals who need reliability, clarity, and precise range estimation during tactical or hunting sessions.

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.
