Things to Consider Before Buying

With these reviews for the best optics for PCC, you would still want what criteria to look out for in purchasing one.


Red dot sights can either be open or tube style. Tube styles are closer to traditional appearance. Allowing the user to apply covers and filters to the lens is beneficial for bright conditions.

Open sights, on the other hand, consist of only the base and objective window. Filters cannot be used for this style.

Projection Type

Optics include both reflective and holographic sights. Holographic means the view is illuminated from the front of the lens, and a laser light is projected to the sight window to create a red dot for aiming. Reflex sight projections are usually used in recreation. LED light is positioned behind the lens to your line of vision.

Reticle Style

This is the red dot used to aim at the target. They are designed for easier shooting in low light conditions. The dots and marks relate to the target. Size can be adjusted – a bigger dot is used for faster targets.

Sight’s Battery Life

Sight’s Battery Life

Battery life is essential. Longer battery life makes sure that the reticle is ready at any time, and your view will not go out as you are aiming at a target. Without this, aiming can be more complicated, and accuracy is compromised.

Durability and Flexibility

Go for a red dot that can withstand harsh conditions. The device should withstand heat or cold and still deliver precision. Moreover, look for a red dot that can be used for more than one firearm. Enthusiasts would mostly have more than one and might want to interchange guns and optics.

Easy to Access Features

Manufacturers have mostly considered that users are engaged in practice or encounters and might need to replace the battery while in motion. As a result of this, most models do not need to be unmounted for the battery to be replaced.
