    • Perfect Optic for EDC!
Color: Red 2 MOA Dot & 32 MOA Circle (HS507...
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

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. Stay healthy and safe friends. Be kind to each other, always ... show more

Over the years have purchased several optics from Europtics. I purchased this Wednesday & it was delivered Thursday. I mounted it today on a Taurus TX22, it is a direct mount.

Tentative review. Item that was shipped was the item that was ordered. Price was acceptable and delivery was quick. I was able to mount the sight without a problem and it has a clear, bright holo sight picture. The shake awake feature works quickly, every time. I have not had the opportunity to fire the weapon (shotgun) with the sight installed so I'll reserve further comments except that the sight seems wee-built and sturdy. ... show more

    • Good optic.. but 4 month battery life. 💩

Good optic with 3 different optic styles to choose from. 10 brightness settings with 2 that work with night vision. I installed this out of the box with my Sig P365XL. But only a 4 month battery life? That’s bad. They promise up to a year but I carry every single day and all day. I’m in a sunny state as well so my brightness has to be at a 7 or higher. I bought it mid February and it’s mid June and it already died. That’s pretty bad if you ask me. But it’s still a good optic. Just buy a 6 pack of batteries for the year. ... show more
