Pros and Cons of Burris Fastfire 3


1. Quick Mount

In general, most customers praised the Burris Fastfire 3 for how fast you could install it. Many knowledgeable gun enthusiasts could install in it between 15 to 20 minutes. You have a blue threadlock 15 in/lb on clamp and 12 in/lb on the sight. Also, a lot of people like how they could sight their rifle in fast with this scope. At 25 yards, you could sight it in within five to eight shots.

2. Bling

While the bling of the RMR or the Deltapoint still outshines the Burris Fastfire 3, this reflex scope asks half the price of the other two. At the same time, you have a fair amount of bling on it to satisfy most budget-conscious gun enthusiasts.

3. The Iron Sight

This Burris Fastfire 3 review covers all the pertinent details of the reflex scope. As an older individual, you may want the red dot on your scope all the time to combat the problem of aging. As a young shooter, however, you can save on the battery and shut off the red dot to use the rear iron sight as you want.

Everything fits on the firearm in a tight and secured fashion through the mechanism. For a gun with a heavy recoil and moving slide like the Wesson M&P 9mm Full-size Pistol, you need a tight-fitting and secured reflex scope.

4. The On/Off Brightness Square

You can turn the sequence on and choose from four different functions:

  • Auto Bright;
  • Low Bright;
  • Medium Bright;
  • High Bright.

You can turn off the auto feature if you prefer. If the sight runs out of battery or shuts itself off for some reason, the next time you tap the on button, the Burris Fastfire 3 will activate to the last mode you selected, saving you precious time. In general, the auto setting does an adequate job with the light sensor and adjusting the intensity as needed.


Like with any product, you have to weigh the pros and cons to decide if you can spin it to suit your purposes. This Burris Fastfire 3 review highlights both the pros and cons of owning the Fastfire 3.

1. The Dot Size

When you first start looking through the scope to fire off a couple rounds, the first realization you come to is how the dot size looks so small. The first couple shooting sessions will be all about getting used to firing it. After you have gotten used to the sight, however, locating the dot will not pose a problem.

2. No Protective Cover

The Burris Fastfire 3 does include a big sun shade, but unfortunately, they failed to include a protective cover for when you clean your weapon. Why is that a problem? During the cleaning process, you can accidentally splash cleaning solution on the sight, which means you have to clean it all over again.After you have zeroed in the rifle scope, you really don’t want the inconvenience of going through the process of dismounting the scope just to clean your rifle.

3. Faulty Units

This Burris Fastfire 3 review looks at when this reflex scope worked and when it failed. For a lot of customers, the quality never became a problem. Where it did occasionally fall flat on its face was when the unit had a fault from the factory.

For example, the unit had a faulty switch or one of the screws did not tighten into the rifle when putting it together. Duds happen in almost any product line, but this was one of the most common complaints, and you can remedy it with the Burris lifetime warranty.

Who Is This Product Best for?

Anyone who loves hunting or target shooting will see the value in a reflex scope like the Burris Fastfire 3. For older eyes that don’t focus as well on an iron sight, you can keep both eyes open and still fire with pinpoint accuracy.

Target shooters may also find it makes hitting the target much easier. However, sometimes the red dot will interfere with hitting the bullseye.

For the hunter, where you’re not shooting for points, the Burris Fastfire 3 becomes especially useful because you can shoot with relative ease.


The Burris 300235 Fastfire III No Mount 3 MOA Sight is priced at $199. You can also purchase the Burris 300234 Fastfire III with Picatinny Mount 3 MOA for $204.99 and the Burris 300236 Fastfire III with Picatinny Mount 8 MOA for $197.00 on Amazon.com.


To sum up this Burris Fastfire 3 review, this reflex scope looks fantastic, and it does a phenomenal job of helping you hit the target. As one of the more budget-conscious scopes on the market, you will find a lot of value in owning this reflex scope if you have a tight spending plan.

Another deciding factor on whether you should buy this product is the lifetime warranty on this product. When you buy from Burris, they back their products. One customer even noted how when his product broke and it was his fault, the company still paid to repair it. Not every brand has the courage to stand behind its products like that.
