There are many drawbacks at start with the proper lightening for aiming point. For small firearm it was impossible to get proper ambient light and use incandescent bulb that could drain battery faster.

Then the first electronic red dot sight was launched by the Swedish optics company Aimpoint AB with reflecting curved mirror and LED. At this time the success ratio was 100% and was very popular. After this the red dot sight technology was stepped in the world of optical technology.

It could be mounted in all compatible firearms at that time and soon many manufacturers made this sight to flood the market. It light emitting diode LED used in the technology able to run 1500-3000 hours on lithium batteries.  In 2000 red dot sight is open to use in field names Aimpoint CompM2 referred as close compact optic.

The Reticle Sizes: Professional Secret to Use

red dot reticles

The reticles are necessary for the point aim to the target. The more glowing reticle dot, cross, bull-eye the more precise target acquisition can be achieved. The reticle sizes are measured in milliradians (mrad) and minutes of angles (MOA).

The red dot reflexes are mounted on shotguns and rifles with the reticle 2 to 5 MOA. A larger brighter red dot sight is more helpful for fast target acquisition but may inhibit precise aiming. On the other side, the rifles use comparatively smaller red dot size about 2 to 3 MOA. For overcoming bright illumination of dot in the late 1900, reticles of size 3, 4.5 and 6 mrad also used.

Mounting the Very Conscious Discussion Factor

Prism Sight

The prism sigh is next level red dot sight. It uses prism and LED which reflected on to a reticle then terminated on target. It is more traditional and compact design with comparatively smaller viewing angle. It is popular for aiming in harsh shooting area and with-stand environmental conditions.

Pros of Using Red Dot Sight

The most important pros are cheap in price than thermal and night vision technology. East to use and can be mounted on rifles, handguns and pistols. Always choose the best red dot sight for your firearm hunting.
