Common FAQ

MOA Reticle Dot Sizes

68 MOA reticle at night

In competitive shooting, it's common to find targets set between 10 to 25 yards, though some events might position them as far out as 50 to 80 yards.

For enhanced target spotting and heightened accuracy, especially for individuals with astigmatism, a more prominent dot is advised.

This larger dot size not only aids in maintaining sight of the dot amid recoil but is particularly beneficial when shooting with a PCC. With a more sizable dot, targeting using a PCC becomes effortlessly precise with less dot tremor.

Long Battery Life

Red dot technology is improving, and as a result, battery life on these optics are becoming absurdly long, nearly infinite. 

No need to worry about forgetting to turn it off after a range trip.

If battery life is a concern for you, we recommend choosing an optic with a battery life of at least 50,000 to 100,000 hours, as most reflex sights on the market today have that capability.

Shake awake optics are great, but they will remain on if the firearm is constantly on the move or inside a vehicle.

Enclosed Emitter VS. Open Emitter 

open emitter led blocked by melting snow

An enclosed emitter will be the best option to protect the lens and emitter from dust and water, and making it full weather proof.

An open emitter sight can't defend against dust, moisture, water, or debris. Anything can get in there and completely obstruct the reticle projection.

If you like the Trijicon RMR, Holosun 510C are your favorite sights, but you would like more protection.
