Mark III free gun reflector sight mk 9 variant. Another type of optical sight is the reflector (or "reflex") sight, a generally non-magnifying optical device that allows the user to look through a glass element and see a reflection of an illuminated aiming point or some other image superimposed on the field of view.

When red dot sights started to appear at the practical shooting competition circuit in the 1990s, reticle sizes of up to 3, 4.5 or even 6 mrad (10, 15 or 20 MOA) were common in order to compensate for the lack of bright illumination. However, as red dot technology and production quality has advanced, the market trend in all types of sport ...
Reflector sights were invented as an improved gun-sight and since their invention they have been adapted to many types of weapons. When used with different types of guns, reflector sights are considered an improvement over simple iron sights (sights composed of two spaced metal aiming points that have to be aligned). [16]
The Chiappa Rhino is an example of a pistol with a low bore axis. The SIG Sauer P226 is an example of a pistol with a high bore axis.. The recoil from a fired cartridge (and the action movement) exerts a rearward impulse along the bore axis, which is commonly above the center of mass of the gun.
Comparison of milliradian (mil) and minute of arc (moa).. Since adjusting the point of impact to match the point of aim is relatively simple with any type of adjustable sights, the primary goal of accurizing is to increase the precision of the firearm, which is generally measured by looking at the dispersion of a number of shots fired at the same point of aim.
The user then adjusts the iron sights or scope reticle to align the point of aim with the projected laser dot. Another more commonly used type of laser boresighter is attached to the muzzle of the barrel, either inserted straight into the bore ("arbor" type) or held in alignment with the barrel via a magnet , and projects a laser beam onto the ...
Iron sights are typically composed of two component sights, formed by metal blades: a rear sight mounted perpendicular to the line of sight and consisting of some form of notch (open sight) or aperture (closed sight); and a front sight that is a post, bead, or ring.
These shape connections prevent ever showing any exterior damage from mounting work on the sight. The proprietary rail systems use matching slide-in mount fasteners to connect the telescopic sight to the gun. Some proprietary rails also offer the possibility to tilt the sight up to 1° (60 moa; 17.5 mrad) to the left or right.
