Red dot sights place the target and the reticle on nearly the same optical plane, allowing a single point of focus. This makes them fast-acquisition and easy-to-use sights, allowing the user to keep their attention on the field of view in front of them. They are common in speed shooting sports such as IPSC.
A view through a Tasco ProPoint red dot sight. The mid- to late 1970s saw the introduction of what are usually referred to as red dot sights, a type that gives the user a simple bright red dot as an aiming point. [27] The typical configuration for this sight is a compact curved mirror reflector design with a red light-emitting diode (LED) at ...
Iron sights are typically composed of two components mounted perpendicularly above the weapon's bore axis: a rear sight nearer (or proximally) to the shooter's eye, and a front sight farther forward (or distally) near the muzzle. During aiming, the shooter aligns their line of sight past a gap at the rear sight's center towards the top edge of ...
The longer the focal length of the eyepiece, the greater the eye relief. Typical telescopic sights may have eye relief ranging from 25 mm (0.98 in) to over 100 mm (3.9 in), but telescopic sights intended for scout rifles or handguns need much longer eye relief to present a non-vignetted image.
A shooting range, firing range, gun range or shooting ground is a specialized facility, venue, or field designed specifically for firearm usage qualifications, training, practice, or competitions. Some shooting ranges are operated by military or law enforcement agencies, though the majority of ranges are privately owned by civilians and ...

Metallic silhouette is shot with large bore rifles fired freehand without support out to 500 meters, and with large bore handguns from the prone ...
Tritium radioluminescence is the use of gaseous tritium, a radioactive isotope of hydrogen, to create visible light. Tritium emits electrons through beta decay and, when they interact with a phosphor material, light is emitted through the process of phosphorescence. The overall process of using a radioactive material to excite a phosphor and ...
