Works Beautifully on a 22TCM100 1911 frame

This is one solid holosight. It holds zero with no problems. I'm using it on a very unusual caliber. The pistol is an RIA 22TCM100. The rounds are all tactical. They are like small "necked down" .223. Same casing diameter as 9mm. Which this pistol will fire both 9mm and 22TCM. Comes w both barrels. The mags hold either rd. The muzzle flash is monster. But does not impede the shooter. I ran 400 rounds through the pistol with the Burris attached. No problems. You will need to tighten it down. I'm looking for a smaller footprint screw to do a more permanent retention on the pic rail which I had installed to accommodate the sight. Even after it got hot, and **first** time at the range, the ready screw loosened. I used a penny to tighten it back up. Stayed on zero. stayed tight from there on. I forgot to bring the screwdriver that comes with the sight to dial in the MOA. Had merely bore sighted it at home and it was already near zero. I need to dial it in with just a couple fine minor adjustments and it'll be dead on bullseye. Like others here have said, it takes a couple tries to get a quick acquisition getting used to using such a small holographic. But once you're used to it, the red dot will come right to your eye. And for rapid fire shots, it works very well. I dim it a bit and that's just personal preference. I tried a cheaper holosight and like the saying goes, you get what you pay for. One had the front glass pop right off. A friend used another brand that was NOT cheap and it fell apart. Burris warranties these and stands behind their products as I did go online to various forums. The dot, like others explained is not (perfectly) spherical. But it's close enough to drive nails and it's toughness is what counted for me. On a pistol with a super quick 1911 comp reset trigger, that slide will cycle 18 rounds flying/dumping. So that this sight holds up to such rigorous movement is why I gave it 5 stars. I have other high end larger holos on rifles. I almost put the small Trijicon on this but wow it would've killed my pocket book. I'm very happy I saved my hobby funds and went with this. Although this is not inexpensive by any means, it's not $650-$800 either. It's a perfect happy medium. The guys at the range call it the "RoboCop" as this pistol cal is similar to a 5.7. But the blast is massive while the recoil is nill. I get a lot of curious folk whom I let give her a whirl. All smiles. As a nut for 1911 frames, I went this route over the FN and it was quite a bit less of a price tag.. It's a great set up especially now with that Burris. Yes. It'll be a good addition to any pistol set up as far as I'm concerned if you are wanting to use (this type of sight). I'm planning on using this for competitive match. It's not something I meant to carry. Although again, that's personal preference for your specific needs. Good product, good company. I have no complaints. Certainly recommend 👍😋🇺🇸 *See photos* ... show more

Worth the purchase
Style: FastFire III (3 MOA Dot) Pattern Name: Fastfire
Works for my 12 gauge express magnum. I don't really need a red dot but decided to give it a try and this didnt break the bank. The dot doesn't cover the bird even out to 60 yards coming in i kept a good target until my range was met.

Half as much, twice as good. COMPACT
Style: FastFire III (3 MOA Dot) Pattern Name: Fastfire
This is currently attached to my AR-15 300AAC (Blackout) 10.5" Pistol build. It is generally on my Ruger 22/45 Mk III, but that was recently stolen, so I've been testing it out on some different calibers to see how I like it. Normally I list the positives first then the negatives. In this case the negatives are so few I'll get them out of the way now. 1) THIS THING IS SMALL. 2) Thats about it. I got this for the purpose of being used on my Ruger 22/45 Mk III and Glock 22 Gen 3. I never got around to trying it on the Glock, but for the Ruger, there is no other red dot I would rather go with. I don't know how Burris is able to put out such a nice little red dot for the price they do. Its ridiculous. This is on par with some much more expensive dots I've seen. And the versatility of their different mounting options is awesome. I've shot a 10x12 silhouette at 100 yds with this tiny dot on my .22 Ruger with a close enough grouping to impress myself. I currently have it on a 300 AAC (Blackout) 10.5" pistol build mounted at 45 degrees. and I've tried it on two different 12ga. On the shotguns it was too low (waaay to small), but it held zero just fine. On the 300 AAC, it sits a little too low on the 45 degree offset mount I have for it, so I got a handful of different height picatinny risers to see how I like it. I've sighted it successfully for 50 yds and 100 yds on a variety of calibers, and am very impressed with the rugged, compact design. It comes with a weather guard/protector thing that I am VERY grateful for. (I really can't afford to scratch up my glass). The only downside of that, is it is just a little obtrusive when trying to activate the sight, but not unmanageable. I just use my fingernail to squeeze the button, but it would be a matter of seconds or minutes to file down the guard so its not in the way. I find that the auto brightness setting (the first of 4 power setting when turning on the red dot) is always just a tad lower then I feel comfortable shooting with, so I generally do it manually. All in all, I don't think there is a better compact red dot on the market for 2.5-3x the price. It works beautifully on handguns and can hold its own on larger platforms. I am very impressed and am going to Burris for future optics needs. Speaking of which, Midway currently has a sale on where if you buy one of the Burris AR-536 or AR-332 red dot sights it comes free with a Burris Fastfire III. I'm ordering one and can't wait to test out some new Burris glass and have another one of these little babies for a future pistol build. ... show more

Great sight, eats batteries a bit.
Style: FastFire III (3 MOA Dot) Pattern Name: Fastfire
Haven't had this a year yet, but it behaves consistently so it's time for a... dun dun DUN!... Product Review. First off, love the sight itself. It is on my EDC pistol (M&P PRO CORE 9L) and it has been quite good overall. It doesn't like being dropped on the floor (Thank you, Mr. A-hole housecat knocking it off the nightstand), and landing on the shield, which dented/deformed a bit, and forced me to re-zero it, but it's been perfectly fine since then (thru slightly over 2000 rounds since it was mounted) The red dot is clear, bright and well defined, and co-witnesses just fine - works with the suppressor-height sights on the M&P, and I can still use them even with the red-dot off. The bottom of the front sight post & the dot are visually cut off, but there is enough there to make using them ok. OTOH, if dropped where it doesn't land on the sight, it holds zero and keeps plugging along just fine. So, it's not bullet-proof, but treated with a modicum of care, it's great. The only *true* downside is that the battery life is nowhere near what was claimed (11,000 hours), at least the way that I always use it: in auto mode. The actual battery life appears to be right at 350 operating hours - figure 6 weeks of carrying every day, turning the sight on 'auto' when getting dressed in the AM. So figure on 8 or 9 of the CR1632 batteries per year, if you're counting costs, or stocking batteries. One thing that's a maintenance item that no one ever mentions is: when you have a MRDS on your EDC, you should expect to have a can of electronics duster-type compressed air to blow all the weird fuzzy crud off the optics every morning, and some alcohol & cotton swabs to get the stuff that won't blow off about once a week. (Not a flaw with the sight, just something to keep in mind.) It's not perfect, but I'd buy it again in a heartbeat! ... show more

Great red dot reflex, bargain price - low profile on a DPMS Panther AR-15
Style: FastFire III (3 MOA Dot) Pattern Name: Fastfire
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. ... show more

It is all about the battery
Style: FastFire III (3 MOA Dot) Pattern Name: Fastfire
It is all about the battery. If you install the battery with no problem you will like this dot scope and give it 5 stars. If you cross thread the battery cover, which is easy to do, send it back and give it one star. I already had two of these that came mounted to a rail with the battery already installed. I liked them both and decided I wanted another one. I went to Amazon and read all of the reviews. Mostly 5 star but way too many 1 star all complaining about the battery installation. My battery installed OK but I can see how it could easily go wrong. Get a good screwdriver that fits the battery cover slot well. Set the battery in and you will find that it will not snap into place or even try to lay perfectly flat. Set the battery cover in place and turn it backwards several times to see if it is setting down flat as it goes around. When everything looks right turn it in the other direction to tighten it. It helps to have it on a nonslip surface so you do not have to hold it when you are turning the battery cover. If all goes well screw it on down and stop when you feel it start to tighten up. If it is cross threaded send it back and give it 1 star. Even though there are many 1 star reviews there are many more 5 star. Good luck. It is a great value for the money. ... show more

Game changer for turkey hunting
Style: FastFire III (3 MOA Dot) Pattern Name: Fastfire
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. ... show more

Battery cap is virtually impossible to install correctly. Pass.
Style: FastFire III (3 MOA Dot) Pattern Name: Fastfire
I have the same complaint several others here have: The battery cap and fitting is absolutely worthless. During the initial unboxing, I had a lot of trouble installing the battery cap after placing the battery into the unit. Eventually, I thought I had it tightened sufficiently to work, and went onto the range for target practice. I got through a couple of magazines and then realized the red dot had disappeared. Looked at the unit and the cap had flown off. Thankfully, among the empty casings on the bench, I was able to find it. I removed the optic and placed it in my bag to tackle once more when I got home. When I got home, I got a larger screw driver, applied pressure directly down on the cap - as some had advised online - and promptly stripped the cheap screw driver grove, still unable to get the threads to align. As far as I could tell, the optic itself worked well, but this battery cap issue is a fatal flaw, in my opinion. Pass on this one. ... show more
