Selection and use of a red dot gun sight

Analyze your specific areas of interest by understanding your EXACT need (war, target shooting, experimentation, pistol, rifle, shotgun, wet, desert, under water, etc. )and purchase a Red Dot appropriate for the task. Most Red Dot scopes are fixed, unmagnified devices and some offer mild magnification. There is a large variety of products on the market ranging in price from $25 to $1000.

Picatinny rail for a rifle

Mount the sight on your firearm. If your receiver is not drilled and tapped for a Weaver-style Picatinny mount, you will need to do so. The Weaver will work for other types of scopes should you have more optics for a particular gun. They are available through many manufacturers and can be affixed to rifles, pistols and shotguns.

Go to the shooting range and zero the the scope. Sight it in at the distance you are most likely to use the gun in the field. Zero a hunting rifle at longer range, a pistol at shorter range. The sights utilize an illuminated dot in the center of the optic rather than the classic cross-hair reticles. Put your dot right on top of the bull's eye. Many scopes allow the brightness of the of the dot to be varied for low light and bright light situations.

Shooting competitive sports that involve targets moving at predictable speeds can be enhanced by calculating the speed and range of the target and adjusting the dot further in the direction the target will be moving. According to the Aimpoint, a longstanding industry leader, "Tests performed by the military have repeatedly proven that one single red dot is the reticle with which marksmen most quickly fire a well-aimed shot."

Shooting small targets or targets at greater distance can be addressed by understanding the relationship in the size of the dot and brightness settings.


  • Some sights are less resistant to inclement weather. Make sure you purchase a unit that will perform under conditions appropriate to your needs.


  • When headed out to shoot or hunt, remember to take an extra battery for your Red Dot sight.
