Burris 300234 FastFire III Fast Fire 3 with Picattiny Mount 3 MOA Red Dot Sight

I mounted this Burris FastFire III on my shotgun I use for turkey hunting and it has been a game changer. I love it. The dot is crisp and easy to pick up, even in bright daylight, and the automatic brightness adjustment works very well. It holds a zero perfectly, even after hundreds of rounds, and the sight picture stays clean and uncluttered. I really like the top mounted battery. No need to remove the optic and re-zero just to swap batteries. Controls are intuitive, and the build quality feels rugged enough for real use, not just the range. For the price, reliability, and performance, the FastFire III is a fantastic optic that delivers far more than expected.

My only gripe with this sight is how finicky the battery cover is. It was very difficult to screw the cap on without cross threading with the battery in place but once I got it together, the sight worked great and held zero no problem on my CO2 blowback airsoft rifle. The included lens cover is awesome, it just easily snaps on and off and covers both the front and rear with a plastic/glass. I am not sure how it will hold up to impact from a BB but it is a lot better than nothing. The auto brightness setting works great while transitioning from bright to dark areas and vice versa. I have high hopes for this sight on my firearms in the future.

Rettifico recensione iniziale...dopo un paio di sedute e relativa taratura, trovo che la caratteristica tanto declamata che indica la non influenza del parallasse completamente non veritiera,semmai qualcuno leggesse questa recensione mi convinca del contrario spiegandomi cosa eventualmente io possa sbagliare nell'utilizzo.....PS 347 €uro!!!!

I spent a half day sighting in and plinking at golf balls at the range and I am VERY happy with this red dot reflex. I'll provide a more complete review when I've spent more time testing it with a sand bag rest at longer ranges; right now, the variations in shot placement definitely reflect the quality of the shooter and not the sight! This package includes the rail mount base plate with thumbscrew and hardened alignment pins (perfectly tight fit between my flat top AR and the Fastfire III); Torx mounting screws with captive external tooth lock washers (no Loctite needed, with 1 spare screw/lockwasher thoughtfully included in case you lose one); Torx wrench to install the 2 semi-permanent screws; jeweler's screwdriver (nonslip matte finish tip, swivel top plastic handle, much better than needed for adjusting windage and elevation); battery; dust cover/sun shield (not pictured, nice bonus); soft fabric storage pouch for the sight + base + cover; and very minimal mouse-print instructions that experienced shooters won't read anyway. Get your reading glasses and take 1 minute. Before you tear up the battery cover like I did. Things I'd do differently next time: 1. Don't bother with a bore sight. I suspect the factory settings were just fine because I spent most of the day undoing the elevation and windage adjustments I'd made at home based on an admittedly cheap bore sight. Ammo is too expensive and rare to waste like I did. 2. Buy a Flat Top Riser Scope Mount. This sight is SO low profile I couldn't get a good cheek weld with muffs on, the red dot seemed to be at the very top of the lens. At times I thought I'd accidentally turned it off, or maybe the battery had died. No, just shooter error. Use plugs alone, or raise the sight about ½” -3/4" with a riser rail. 3. Do NOT use the tiny jeweler's screwdriver to reinstall the battery cover. Yeah, it comes off with one... Use a big fat tip screwdriver that fills the slot. Or maybe a penny or nickel. The body of the sight is hardened aluminum; the battery cover may or may not be hardened, but you will definitely tear up the screwdriver slot on the battery cover if you get so excited about your new toy that you just can't bother making a trip to the garage for the correct size screwdriver. Buddy, listen to me, there is NO SENSE reading this review then repeating my mistake. You just spent $250, now treat it like a quality optic worth at least that much. Thank you. The soft rubbery black rectangular pushbutton on the left side is nearly flush with the sight and rotates through 5 settings: Automatic brightness, Hi, Medium, Lo, and Off. The pushbutton does not give any audible and only minimal tactile feedback, so watch the dot. I was shooting on a bright sunny day, standing in both shade and full sun, shooting in the afternoon toward the Sun and was able to find the dot even on the lowest setting. The Automatic brightness setting seemed to provide an even wider range of brightness than the manual settings, if that's possible. The bonus dust cover/glare shield cut the dot brightness just a bit (as expected) so you might experiment leaving it on if you find the dot still too bright for dim light as other reviewers on other websites have claimed. The dust cover has a generous relief cut to fit around the pushbutton but my fat fingers couldn't always press the button far enough with the cover on. I may take a Dremel to the relief cut to make the opening bigger, I suspect most of you won't need to. The elevation and windage screws seem to have a very wide range of adjustment. They do not have audible or tactile clicks, which should be unnecessary anyway. You cannot adjust these with bare hands (i.e., without a small screwdriver like the excellent one enclosed) but I cannot imagine needing to make frequent adjustments. NOTE that if you max out one adjustment screw all the way up or down, you cannot move the other. Don't force the second adjustment screw, just back off the first adjustment screw a tiny bit. Then use plugs not muffs. Or buy a sight riser. Because you didn't need to max out the elevation screw in the first place. I've owned a cheap (<$150) red dot reflex sight before, with plastic body and cheap mount. Don't waste your money on a lesser sight. This is a very high quality optic designed to withstand 1000 Gs, with hardened aluminum body and mount. If you need something even tougher, buy the optional Burris mount that surrounds and protects the entire Fastfire III.

Worked perfectly on my SBE3 for Turkey hunting. Only complaint is the battery compartment. Takes some finesse and time to get it to thread properly. Once the battery is installed, leave it.
