This little 507K was purchased to top off a new firearm that was pre cut to accept the 407K/507K. It fit like a glove and was simple to install. It performs flawlessly like all Holosun optics I've tried. The dot is easy to find and the multi reticle gives me 3 choices. This is daylight bright even in the brightest sun. Other Holosun optics I've had take a lickin and keep on runnin. I could by the BIG name super spendy stuff, but why. Holosun is miles ahead of the competition when it comes to design. For me every Holosun product I've owned has lasted. They're well built and priced well. Of course right after I bought this, I saw it on a great sale for $70 less. That's just my bad luck. Two big thumbs up Holosun and Amazon. Super fast shipping and our Amazon delivery people are the best of the best. Kind, cordial, and always professional. Happy Labor Day 24 to all.

The quality of the sight is perfect. Fits excellent on my 43x. It’s very easy to function and very durable. You will need an adapter plate if you have an MOS cut but it’s so easy to install. Just don’t over torque the screws and or use extra lock tight and it’s gonna never move on you. Very easy to sight in as well. I would highly recommend this sight. ... show more

The Holosun HE507K-GR X2 has been an absolute upgrade for my carry setup. The green dot is super clear, easy to pick up quickly, and works great in all lighting conditions—even bright sunlight. I love the shake-awake feature, and battery life is phenomenal. Fit and finish are top-notch, and installation was easy with the right adapter plate. It's tough, compact, and reliable—exactly what you want for everyday carry. Highly recommend it if you're serious about accuracy and quick target acquisition! ... show more

Received in new perfect condition. I checked out all the settings and everything is working fine. I’m no stranger to these types of optics. This is my second Holosun. This one is the 507k green dot. My first one is a 407c with solar and red dot. I’ve been buying other brands in green that seems to work better with my eyes. This one is mounted on my S&W M&P 22 Magnum pistol. You can’t go wrong buying Holosun’s. The fit an finish is fabulous. Performance is great along with very good build quality for the price. I plan on buying more in the future. Yes I would recommend to a family member or friend. Very nice product! ... show more

First the bad: The reticle is tilted to one side, it’s not square. With the dot or circle you won’t notice it of course, but with the crosshair-style reticle, you notice it. I’ve read others who have had this issue, I guess it’s within the margin of error so they let it go. It isn’t going to affect shooting to any noticeable degree, but it’s not the way it should be, simply put. Yeah, it’s lower cost than a Trijicon or something, but it’s still high enough price that it should get that right (I have seen and owned cheaper sights, and none of them have had tilted reticles). At times it can lock up and not respond to any input. Happened once to me, wouldn’t change from the dot reticle and wouldn’t turn off. It turns out that Holosun actually has directions on how to fix this, and it’s simple (you hold the buttons or something a certain way, I forget), but if you don’t look it up and see it on their website or a forum, you might be pretty angry about it until you do. Mine responded fine and went back to normal. The good: Well, basically everything else for now (haven’t needed customer service yet, we’ll see). I like the shape, I like the reticle options, I like the brightness and the lens clarity, I like the fit and finish (other than the glaring issue with the tilted reticle), I like how it looks, the weight, etc. Of course price is a large factor here as well. ... show more

Mounted perfectly to a 43X MOS using the DPP titanium adapter plate. Have put around 250 rounds through it and it seems to be holding zero so far. Really like the 32 MOA circle with dot as it makes sight acquisition easier than just a dot.
