What To Look For In A Red Dot Prism Scope?

1.  Size

The size of the red dot sight is very important. The size of your weapon more or less determines which sight is right for your needs.

2.  Battery & Battery Life

The type of battery for the scope should be seriously considered when you think about buying a red dot scope. There are some which have regular batteries while there are others with advanced batteries. The call is yours to make.

Additionally, with the battery comes its battery life. This is another factor you want to take into consideration. How long is the battery life of the batteries for the scope you want to buy? Long battery life is more desirable than a short one as you want to work for some time before the battery starts to fade away.

3.  Open or Tube?

Another decision you have to make is whether to go for the open or tube option. The open style uses a small square-shaped window. On the other hand, with the tube option, everything is in an enclosed tube.

The open sight offers a better scope of vision but is more susceptible to damage. The tube option gives a more limited scope of vision because it is enclosed but lasts longer since it is enclosed.

4.  Reticle Size

The size of the reticle is also very important. Take into serious consideration the types of shots you will be taking and their distance when choosing reticle size.

A smaller reticle works great for taking precise shots at longer distances as it covers less area, therefore the shot becomes more precise to the target. Larger reticles are ideal for newer shooters as it is easier to see, however they can obstruct the target view at a longer distance. A general rule of thumb is to look at it in terms of inches versus yards. So a 1-inch red dot is ideal at 100 yards and a 2-inch diameter is ideal for 200 yards, and so forth.

5.  Reticle Type

There are different types of reticles with their strengths and weaknesses. Some are dots, hollow circles, chevrons, triangles, hash marks, crosshairs, and combinations of these.

Dots and circles are fairly easy to see and they tend to center naturally. Triangles, circles, chevrons, and hash marks often correspond to specific target sizes and function as an elementary range. With crosshairs, you “quarter” a target to help center your point of aim. Hash marks give you aiming points for targets beyond zero distance.

6.  Brightness Settings

Brightness settings will depend on the lighting conditions, your eyesight, and your reticle style. As the brightness is increased, aiming points wash out the target image. You want to consider your brightness settings and how good is your eyesight when deciding on your red dot scope.

7.  Power Source

What kind of power source does the red dot scope use? This is something to consider when deciding on your purchase.

8.  Magnifier Compatibility

Magnifiers are a sticky factor to consider. They bring the images closer with greater detail but they also magnify the aiming reticles and flaws. You want to consider if you will need magnification and just how much you will need based on what you will be doing with the scope.

9.  Dual Projection

You get dual projection from the red dot sight; it includes holographic and reflex sights. Can you work easily with dual projection as the reflex sights are more common in red dot sights which are for recreational use?

10.  Price

High price doesn’t always equate to quality. It is best to figure out which features you want in the scope and don’t just go by price.

Types of Red Dot Prism Scopes

1.  Standard Rifle Optics

Most red dots feature tube-based designs. They have a 2 to 3 MOA red dot, a 25 mm or higher objective lens and are designed for close to moderate shooting. The range and versatility can always be increased by mixing standard rifle optics with a night vision optic or a magnifier.

2.  Miniature Red Dots

Miniature red dots are very small. They are fitted as pistol sights and backup sights for rifle optics. The trend is that they are getting smaller and smaller each year and quickly becoming a real option for CCW.

Red Dot Scope Accessories

1.  Mounts

There are many red dot mounts on the market. Mounts help enhance the shooter’s abilities. If you will get a mount, do spend some time finding the right amount for your system.

2.  Adapters

There are many different adapters on the market. You have to find the best one which fits and works well with your red dot scopes.
