Our Review

Burris is a classic name in optics, and I think that there’s a reason that they’ve been around for so long. The FastFire III offers a little bit of proof of this. I found that I actually really liked the FastFire III, and I can understand why it’s one of the metrics of comparison for relatively low-cost red dot optics.

I usually start out reviews by talking about the lens, but I want to break from that a little bit here by saying that just taking a look at the FastFire III, I can immediately see why it’s so popular. It’s clearly well-built. You can practically see the craftsmanship that’s infused into every bit and bezel of the FastFire III. Real care was taken, and it pays off. It’s a pretty beautiful optic all around.

Equally beautiful is the utter clarity of the lens. It gives you a bright and clear image of everything in view. The field of view is as wide as an optic of this size can allow, and its true 1x magnification makes what you see around the optic what you get within it. This immaculate lens lets you shoot with accuracy out as far as 200 or 300 yards. Also, there’s an included sunshade meant to make it easier to use on super bright days.

You’ll be assisted in that mission by either a 3 MOA or 8 MOA red dot. In either case, you’ll have a crisp and round dot that is exactly what you imagine when you think of a red dot sight. It features an automatic and a manual mode for setting brightnesses, and the auto mode is really fairly good. It does make it easy to get a comfortable brightness in really any situation without really having to get your hands dirty, but the automatic red dot may be a little dim for some and you may end up overriding it to get a better, crisper dot.

The dot will last a long time thanks to the fairly long battery life. This will be bolstered, too, by the fact that it turns off automatically after several hours. While this may not seem ideal, it is at least some form of protection against your battery being left on until it dies should you ever forget to turn it off. When the time does come to say goodbye to your battery, it’s easy enough  to replace thanks to the battery cover on the top. This spares you the headache of having to remove the sight in order to replace the battery.

On the other hand, the battery that the FastFire III uses is a little irregular, so if you place an order, you’re probably going to want to order a multi-pack to ensure that you always have some on standby. Also, the battery compartment’s lid is easy to put back on incorrectly and cross thread, so you want to be careful when replacing it.

The sight is pretty easy to mount and set up. If you get the mount bundle, the included mount isn’t very protective. Bear that in mind if you expect to be in rough-and-tumble situations a lot, because the sight already scratches fairly easily and you want all of the protection you can get. Unfortunately, the sight sits a little high when it’s mounted, but you get used to it with time and it’s a matter of personal preference anyway.

Once you set it up, it zeroes easily, thanks especially to the well-placed adjustments that are recessed into the top and side of the sight. These are just one example of how the design of the sight is altogether really comfortable, organic, and intuitive. The buttons on the sight can be a little hard to use while wearing gloves, though, especially the push switch on the side of the sight.

As I said earlier, in terms of build quality, the sight is cleverly constructed. The compact design ensures that it’s functional and not just a big hunk of plastic and glass on your gun. It’s lightweight and compact, but despite this, it’s still very sturdy and will stand up to quite a bit of use. There are the odd stories here and there of it losing zero or the sight simply breaking after a few months, but these seem to be far from the norm. Most people have excellent experiences. The only drawback in terms of construction quality is that, as I said, it does seem to scratch easily.

Burris also seems to have a fairly solid warranty, similar to the Vortex VIP warranty. Called the Forever Warranty, the warranty ensures that you get fully transferable lifetime service for your sight. If you run into any issues, simply send them the optic and they’ll either replace or repair it at no charge, with no warranty card or receipt necessary.

Should You Buy It?

The FastFire III is a strong sight and is an incredibly good deal for the money. If you’re looking for a high-quality red dot sight that will do everything you need it to, then you can’t really go wrong with the FastFire III. Yes, you should buy it.
