How to use Primary Arms Micro Red Dot Sight.

What to look for while buying the Best red dot magnifier

The size, pattern, and color of the dot

The size of the dot should be big enough for you to see.  If it is too small, you may have a hard time using your device. Dots that are too large are likely to obscure the target.  The unit of measure for dots is MOA (minute of angle). 1 MOA is approximately 1″ per 100 yards.

Therefore, if you own a 6 MOA device, it means that it covers a 6″ area on an object that is 100 yards from you. For users of AR 15 and the like, 1-4 MOA is the most appropriate. Anything above 5 MOA will just serve as an obstruction.

The pattern is a matter of individuals’ preference. The majority of sights have a dot and hence the names. However, it does not mean that there are no other patterns in the market. Getting crosshair reticles or many others available is possible. Also, some sights have a range of patterns that you can choose from.

You apparently think that because it is a red dot, the color the dot is definitely red. Not necessarily.

Other colors such as blue and green are also there. In most cases, red is the most preferable as it is easier to use in most conditions.  However, blue can turn out to be the best in the majority of bright conditions.

When shopping for a sight, try a couple of them and determine which color of the dot suits you more.

The lenses

Since it is an optics device, the lenses have to be good. Any red dot worth its salt should have fully multicoated lenses. This is a critical factor in getting a clearer picture and better light transmission.

You will find cheaper red dot magnifiers that feature only one lens with a multi-coating. The other may have a single coating.
While these models may not be a bad choice, after all, it is always best to go for fully multi-coated lenses.  There is a material difference between the two types of lenses, and it is best if can pinpoint out it before you purchase it.

The magnifier size

The magnifier size is another critical factor that you need to note. Your magnifier needs to be compatible with your rifle. If it is too big for your weapon, then it will serve as an obstruction.

It is also critical to ensure that the magnifier is compatible with your red dot and firearm. This is especially valid if you are planning on a handgun or shotgun which has very little mounting options.

Quality and design

Another critical factor to watch out for is quality and design. Doubtlessly, you will want a piece of equipment that is durable. Some rifles have a significant amount of shocks and recoil associated with them.

You don’t want to keep on replacing your optics now and then. Fortunately for you, most of these tactical devices are built to have a certain amount of ruggedness for law enforcement or military use. However, it is always best to be sure.

The style of mounting

Mounting is a critical factor that you need to put into consideration. The best type is the one featuring the flip-to-side option allowing the user to see both with the magnification and without it. Fixed mounts will require you to remove the magnifier every time that you want to use only the red dot.

In hunting situations, you need this option of switching back and forth. After all, you may not know the distance at which your target is.

Types of Red Dot Magnifier

There are different types of red dots in the market. Red dots come in several shapes and sizes, and it can sometimes be confusing when purchasing them. This is notably true if you don’t know what to look for. The red dots that resemble a scope are ‘tube’ style. However, there are those that carry a square shape like EOTech. They are the open type – without a tube.

Red dot magnifiers are electronic or battery-powered. These days, magnifiers utilizing batteries are also coming with a flashlight for use in low lighting conditions.

However, in comparison to the electronic types, you may need to contend with low lighting conditions functionality.

The battery operated types last longer than the electronic ones. But the electronic types come with power saving features where they switch off on their own after a particular time.

Tips for using Red Dot Magnifier

Like most other tactical equipment, you need to know how to use the equipment. One of the most basic of instructions is positioning. Essentially, your red dot should not be too close to your eye. This will produce a tube effect that will obviously impact on the accuracy. Best practice is to position your eye some distance away to avoid this effect and use both eyes.

You need to realize that reflex magnifiers are great at aiming, as well as, using them. Therefore, you don’t need to fret too much about using them. Be assured that you are going to hit your target as long as the red dot marks it.

To shoot your target, place your weapon in a firing position. Then point the red dot at the target and shoot your prey. Always remember to keep both your eyes open and your focus on the target. Nothing should distract you throughout this process.

In bright lighting environments, don’t forget to manipulate the brightness of the reticle. If the lighting is poor, adjust the reticle brightness accordingly. You should note that manipulating the red dot is almost the same as manipulating a riflescope. It will not be so much trouble for you.

Here is a video on how you zero your red dot magnifier.

should you use Red Dot Magnifier?

The real benefit why you should pick a red dot magnifier vs. scope is its functionality and great performance. Moreover, these devices are more secure in comparison to scopes that feature holographic technology.  It is now a proven fact a cracked holographic lens is significantly harmful to the human eye. In actual sense, you can experience a damaged eye in case of exposure to the laser.

Another compelling reason on why you should choose a red dot is their ever reducing weight. Every new model is lighter than the previous one. The main reason for this reduction is their aluminum alloy construction.

However, among the most significant of advantages is their ability to swiftly acquire targets. Red dot magnifiers fit relatively well with a large variety of rifles. Furthermore, you have an advantage of using both your eyes hence increasing the level of your accuracy.


  • Is it necessary to have a red dot sight?

One thing about the red dot is that it gives you the ability to target your prey with both eyes open. This helps with environmental awareness and enhanced depth perception. For carnivore hunters, situational awareness is critical as it may be the difference between life and death.

  • Can I use the red dot on handguns and shotguns

It all depends on the model. In other words, there are reflex sights that you can pair with pistol and shotguns. Know your weapon and acquire the right accessories to go with it. However, you should note that adding reflex sights to the pistols makes them a little bulky. This is a disadvantage if your objective is to conceal your weapon.

  • Should I get a co-witness to go with it?

An iron sight keeps you from getting frustrated if your red dot runs out battery power or when if malfunctions.  Therefore, it is a good idea to pair your weapon with iron sights.
