Modern devices do almost everything for the people, helping in all spheres of their lives, hunting or competitive shooting are not exceptions. Reflex sights are widely used among shooters, because they operate well, providing easy and effective aiming.

The most popular red dot sights are reflex (or reflector), holographic, and prismatic, they all project the reticle but in different ways.

Why do we need a reflex sight?

Due to an LED projection (not laser), shooters see an aiming point onto a lens of the reflector sights. Usually, images are a little bit darker as the lens works like a mirror. One of the main reflex sight benefits is the capability to look through the sight from any positions that don’t influence the aiming point, making focusing much easier, excluding eye aligning, necessary for iron sights. Reflex sight is a good option for many weapons, appropriate for tactical uses, home defense, hunting, general, or an average rifle shooting.

FAQ

How does a reflex sight work?

Reflector sights work with help of an image-forming curved mirror or a lens, in the focus of which ones are a luminous or reflective overlay image or reticle, creating an optical parallel beam of rays or radiation to project a virtual image of the reticle. So the viewer can see both the field of view and the infinity image at the same time. The reticle is placed with the device in alignment, regardless of the viewer’s eye position, eliminating most sighting errors (such as parallax and others), which can be in the simple sighting apparatus.

Are reflex sights accurate?

Reflector sights work faster and more accurately than iron ones. Comparatively, with a standard variable optic, they feature 0 magnification. The reflex 1x optics are usually more lightweight and shorter than standard scopes. Reflex sights are mostly useful for close and mid-range shooting.

What is the difference between a red dot sight and a reflex sight?

Reflex sights are a type of red dot sight. The red dot allows it easier to acquire the target and to aim with both open eyes, as there is no eye relief. The Reflex sight is different from the red dot sight by its lower cost.

Do reflex sights work at night?

In low light conditions while shooting a red dot can be seen better than a night vision scope.
In complete darkness, it is necessary to combine reflex sights, compatible with a night vision device (NVD), which senses radiation on a wavelength, invisible for the human eye, ensuring a visible green image.

Do the Navy SEALs use reflex sights?

Since 2000 the U.S. military has implemented a red dot sight on the battlefield, the Aimpoint CompM2 (the “M68 Close Combat Optic”). Among the Marines, Navy Seals, and U.S. Army self-illuminating Trijicon scopes and sights approved as the most sophisticated and reliable combat optics into field use.

Which is better reflex or holographic sight?

Reflector sight shows more colors than the holographic sights. A reflex sight differs from a holographic reticle by shapes versatility such as circular shapes, points, crosshairs, etc. The reflex sights have a clean-looking sight, meanwhile, the holographic sight has a huge body along with the pattern, blocking your vision. Reflex for handguns with vertical recoil, holographic for horizontal.

Conclusion

All manufacturers promise that their reflex sights will help the shooter quickly and easily to project on to the target. Apart from reliable optics brands such as: Trijicon, Vortex, Sightmark, Swampfox, there is Holosun (HS510C Circle Dot Open Reflex Sight) that can be denoted among the reviewed goods’ list for its reasonable price with good features (motion sensor with Shake Awake option and dual-power supplies). There are exposed and tube-style reflex sights, the first one allows scope easier and faster. Some of the benefits that reviewers often note are green illumination color, night vision compatibility, parallax-free, quick release mount, and warranty.

My love of guns is in my blood, since childhood I have spent hours enjoying the beauty of guns and adored going through their parts.

Tactical accessories are another passion of mine that I could write about endlessly - my house and garage are full of tactical gadgets, luckily my family shares my interests.

I'm infatuated with traveling that's why work at one place with a daily routine and standard schedule is not for me. I prefer copywriting and English tutoring as a freelancer. I live in a male family among constant talks about cars, guns, hunting, fishing, and, of course, dinosaurs 😊.

My husband is an obsessed hunter, and my two sons are fans of «Demolition Ranch» of YouTube blogger Matt Carriker. They are my best consultants about weapon and all-around ammunition topics. All together we share a love for adventures. Every camping or mounting hiking trip is a "small survival", giving irreplaceable experiences. Nothing can be better than the satisfaction of observing wild nature.
