Design Improvements & Review:

The SWAT illumination in this scope offers the ability to control various red or green illumination levels in reticle. This allows the user to get best view in different light or weather conditions. The patent of lever lock system used in this scope is pending. However, it’s designed to make this scope quick to apply and remove, on all types of Picatinny rail system.  Below you will find our favorite reasons why this scope is so practical.

1. Build Quality:

Many people doubt the built quality of this scope as it’s made in China. However, this is a truly solid scope made out of aluminum to ensure that it’s pleasant looking, lightweight and durable. The feel of this scope makes most people think it should cost a lot more. You also get a lifetime manufacturer’s warranty against any defects in materials and workmanship.

2. View:

The tube of this scope has a length of 4 inches and a diameter of 1.5 inches, this allows it to sit nicely on the rail. The size of its lens is 32.5mm, which is the largest in this price range. The emerald lens quoting is highly effective in preventing stray light from entering by cutting any reflection and glare. Therefore, the view you get is clear, sharp and pretty wide.

3. Performance:

The green setting of this scope is great for bright conditions, such as direct sunlight, and the red setting is suitable for low light conditions, such as inside shooting range. The ability to adjust brightness allows users to play according to their strengths, and without any distraction in all kinds of light conditions. This scope is ideal for home protection as the red light allows quick target acquisition, even in dark conditions.

The continuous rheostat knob allows the shooter to choose ideal brightness setting, rather than adjusting the dot intensity by preset clicks. The unlimited eye relief in this scope is highly beneficial, and the forward and backward offsets of the mounting system is great to match shooter’s stance and position.

4. Attachments:

All the essential attachments are provided with this scope. Therefore, it comes with two batteries, flip-up lenses caps and two mounts. Although, lens cap is the only part of this scope that is made from plastic, but they are removable and of high quality. An extra battery is provided, which is reported to have a shelf life of over 5 years.

It comes with an extremely convenient feature of quick detachment. However, despite quick removal and attachment option, the sight does not become loose after continuous use.

Overall Pros:
