HE507COMP-GR / HS507COMP CRS 2 MOA Dot & 8/20/32 MOA Circle Reflex Pistol Sight with Large Objective Lens - Durable Shake-Awake Parallax-Free Aluminum Handgun Sight - Green & Red Options

I'm using a more expensive Ultradot, and a less expensive Vortex Viper on different pistols, and I honestly like this Holosun the best. The green dot is more visible for me, and for someone that wears glasses and has some astigmatism, the "blur" my eyes can make of a dot are much less impacted on green than they are on red for the same size dot, so I recommend green, as well as the other features on this sight as well. This is smaller and lighter than an ultradot, and more visible. It's similar in size and weight to the Vortex Vipers, but the Holosun can be click step adjusted for MOA WITHOUT having to unscrew any "lock screws" or just having a free rotating adjustment screw like the Vortex. The Holosun can also have the battery changed without removing the sight or affecting zero, whereas a Vortex must be removed to get the battery out of the bottom of it. I also really appreciate the multiple choices for reticle. You can use the dot, or different MOA circles, or a combination of both. I chose both the dot and the smallest circle simultaneously, because the dot is zeroed for center bull, and the smallest circle they have is almost an exact fit for the black on the target, making it almost like putting an aperture site ring around it. Makes it every easy to recover after recoil to put it back on target, and when there's time to be very precise in slow or timed, I find myself centering the green ring around the black circle and having that be very intuitive and natural to do. In faster stages I'm more working on getting the dot centered quickly, but the ring helps it be a bit easier to pick up after recoil. This is my current go-to now. Just know that if you don't have a flat spot milled out to mount it directly, you need to buy a weaver/picatinny mount for it, which is not very expensive, but I think should have come in the box like my other dots came with. At this price, a $15-$20 separately boxed and shipped mount should have only set them back $10 to include in the same box already.

Best optic I've ever used. Huge windows, and with the green dot I'm not getting any of the usual starburst pattern I get from red dots due to my astigmatism. Just a very thin, faint fuzzy area around the edge of the dot that's all but unnoticeable. I really like all the reticle options and shakeawake features as well, though I'll probably just stick with the 8 moa circle with the dot when competing. It's a great fit on my Canik Rival S. It's amazing how quickly and easily I find the dot and how simple it was to zero in at the range yesterday.

I got an email asking did this purchase meet my expectations. Nope. Not even close. This thing is hands down 1 of the best on the market. I shoot competitively and this (in my opinion) although marketed towards the competition shooters. This optic is not only for competitive shooters... Anyone can pick this up and up their game tremendously. There's a reason this is 1 of highest rated optics with competitive shooters. I had a police officer buddy swing by last night. 30 seconds later he's going to order 1 as well. Quality is top tier. Functionality.... with 8 daylight settings and 2 night vision... Customize it for numerous shooting disciplines. Crystal clear glass. Speed of target acquisition is insane. You will not find more bang for your buck. Stop looking and hit add to cart. You won't be sorry.

New to dots on pistols. The thing I like best on this one is the large window and the ability to set it for up to 4 different symbols or any combination of them. Makes for easy acquisition and by picking the right size combination of symbols it makes distance estimation easy. The shake to wake is very good as is the adjustment for brightness. I got it in green.

This is probably the best red dot optic you can buy right now that rivals the Trijicon SRO and for sure better built and reliable than the Vortex Defender XL. I bought and own 5 of these.

Excellent as always. This optic is a great value compared to some that cost much more. I prefer the green dot to the red due to astigmatism in both eyes. It's super easy to get on target, as well as reacquire after a shot. This one has several options for the dot itself, as well as varying brightness levels. Not my first Holosun and won't be my last.

Love the 507 Comp and Holosun in general. I run this on my EDC. Large windows, clear glass.

Easy installation with the DPP Titanium Adaptor Plate for the Glock 17 MOS Gen 5. Easy to see the green dot and adjust to your likeness. Recommended.
