What Makes a Good Reflex Sight?

There are a few things to consider when buying a reflex sight, such as the reticle, durability, mounting system, and battery life.

Reticle

Reticles come in all shapes and sizes to provide you with a good point of aim.

Each sight comes equipped with various brightness levels to help you shoot in every environment.

Durability

A solid reflex sight needs to be constructed out of high-quality material that is resistant against various forms of damage such as water, shock, and impact damage.

Mounting

You need to make sure that the reflex sight that you are choosing will fit your firearm.

Various models fit all types of rail-mounted weapons, but some reflex sights only mount on certain weapon types such as pistols.

The lifespan of the sights on this list lasts from a few hundred hours to several years.
