Reviews & Ratings for Burris FastFire AR-F3 Flattop Sight — 17 reviews — Page 1

This is my fifth FastFire 3; my second with the AR-F3 base. I have both 8- and 3-MOA models. They always work and the batteries last almost forever.They are all on rifles and carbines, both .22 and 9mm, used in Steel Challenge, IDPA, and fun matches.

Easy to use and works great! Recommended to me by a friend and I recommend it to anyone looking for a good sight

Overall good sight, but the tiny buttons are guarded by the riser/mount and a pain in the butt to access. I have much better sights for half the price in the Sig Sauer SOR52001 Romeo5 and Sightmark Ultra Shot R-Spec Reflex Sight.

Ive used the fastfire atop a benelli M4 12 gauge shotgun and fired hundreds of rounds. Anyone claiming it doesn't hold up to recoil is wrong. Tracks very well for wing shooters. No, its not an aimpoint. But it wasn't intended to be an aimpoint. I love mine, I own two.

As of 2/20/20, The Burris FastFire 3 is NOT recommended. My $300 optic failed after 3 shots on an AR, as the battery cap has only 1-2 threads and teetter-totters off the battery spring causing cross-threading, never being secure. I am looking into getting a Vortex Venom as a replacement because I only want parallax free red dots with unlimited eye relief.

I bought the Burris AR-F3 Flattop FastFire Sight and have been very impressed with it for a number of reasons. I bought the sight to finish out my M4 build. With the mount it is perfectly suited for co-witnessing the fixed front sight on the rifle. It attaches very easily to the picatinny rail on the flat top receiver and it is very easy to align the dot with a laser bore sighter. Once properly mounted I took it to the range and was shooting half inch groups at 50 yards with a few adjustments and about 15 rounds. I was very pleased and how easy it was to mount and how quickly I could complete the "sighting in" process. The sight is well protected by the steel mount which came attached right out of the box. The controls are very simple, one button on the left hand side is very accessible and has only 4 settings, off, and three brightness levels. To adjust the location of the dot you only need to use the small flat blade screw driver that comes in the box. I am always impressed with technology that is simple to use and does what it is designed to do. This sight fits that description to a "T". I cannot yet speak to battery life but may follow up with that later. I can say that it holds zero very well as I have shot a couple of hundred rounds through it with no issues. This is my first Burris product but it will not be my last.

I ordered and the dot was very blurry. Sent it back and the new one ,Well it's now a line,no dot. Cleaned it and still a line, no dot.
Burris does not have ANY Quality Control!
Save your money.
I Send it back and they'll send me another piece of C..P.
They make it,ship it and f...... it. Junk.
And as far as putting it no a AR15 flat top, too low!!!
Spend less. Spend more but don't buy Burris!!!!
I use Sightmark (cheap,$50.00),EOTeck$$ and Trijicon$$$. All much better!!!

I received a Burris FastFire III as part of the rebate program earlier this year. At the time I wasn't sure what I wanted to do with it. I didn't have any handguns I could use it on, and I've never been fond of the 45 degree red dot mounts (Always found them too slow for CQB, especially when mounted on a weapon with a heavier optic.). I came across the AR-F3 mount and was intrigued.

The red dot screws into the mount like it would any other picatinny mount. The mount sits perfectly for an absolute co-witness and has protective ears around the red dot. The overall footprint of the optic system is ridiculously small and it adds almost nothing to your overall weight. I'm currently running this as my primary optic on a 16 inch carbine and over been very pleased with it.

There is also a tool compartment under the red dot. There is a wrench and a torque wrench to secure the base and make any adjustments. I made the mistake of popping the whole unit out, despite it being glued in. Didn't damage anything, but my first trip to the range and the tool compartment slowly worked itself out under recoil. A little glue and the issue was fixed.

Overall I'm very impressed with this set-up. While the FastFire III may not run all that well in the snow or rain (but nothing that can't be fixed with a small cloth), this mount provides a great option to run this optic.

Have this mounted on a DS Arms FAL. Perfect height, excellent quality. Easy to use adjustments and good brightness of the dot. Clear and sharp dot. Well made mount(Nice roll bar type), perfect height for an FAL. Interesting storage compartment underneath the sight, so far seems to stay in place.

For the price I paid, I'm fairly happy with this red dot. The 3 MOA dot however is not super crisp, there is a slight blurriness or starshot around the dot. I owned an Aimpoint PRO before this and that 2 MOA dot was crisp and fine. That is a much more expensive red dot of course and the difference is price is substantial for some folks. I only sold my PRO because it was too bulky for my SBR. The spare battery compartment is actually under the optic in the AR-F3 mount. I don't think that's very convenient as you have to remove the optic but it is keyed so in theory you won't lose your zero or much at least. Overall, the Fastfire is a nice red dot far as features and size.
