HOLOSUN 407/507COMP Series 6 MOA or 2 MOA Dot & 8/20/32 Circle Reflex Sight | Dot only or Multi-Reticle Options, Large Competition Window, Shake Awake Technology, 7075-T6 Aluminum, RMR Footprint

Want to hit your target? Want to not have to squint on a continued search for the reticle? The 507Comp is the way to go.Once sighted in, I can’t miss. Huge window with several different reticle options. Adjustable brightness and motion to activate. Haven’t had to change the battery since my purchase and I shoot regularly, seems like the battery will last a long while, likely due in part to the auto-off feature.Installation took about 5 minutes on my FN509 and this product screams quality. Father-in-law shot my pistol and immediately ordered on for himself. Heat value compared to some other options on the market.

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.

Awesome optic, brand new in box as described, green dot. well made, good value for the money and was easy to install

Super nice optic. Nice big window. Lots of reticle choices. Sturdy and durable. I’ve been running it for two years now. Training and a few competitions. This optic does not disappoint!

I bought the 507comp in green because green works better with my colorblindness. I went to with 507 because I thought I'd want to use one of the circle reticles, but I've ended up just using the dot so I really could have gone with the 407comp. Great optic for competitive shooting (IDPA/USPSA). Would be a little too big for CC.

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.

Nice unit well made and packaged. Impressed with the green color, like it much better than the red I have used in the past. Only problem is turning it off, you need to push the- and+ at the exact same time. With my old rather large fingers its impossible, had to make a special tool to accomplish that little task. Why!Why! make it so difficult
