HOLOSUN 407/507COMP Series 6 MOA or 2 MOA Dot & 8/20/32 Circle Reflex Sight

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.

As a marksman, I highly recommend this sight. I use this on a Springfield M1911 .45ACP, even had it professionally mounted. It’s held up great, and it holds accuracy very well. There’s no device that can make make you shoot better, but a good sight like this one can mitigate a lot of the frustrating variables. I’m landing 80-90% of my shots in the 10 ring on a silhouette at 50 feet.

The Holosun 507 Comp is truly a red dot for competitors and target-focused shooters. I would not recommend putting this "large screen tv" on a carry weapon. I own 8 dots (Holosun, Leupold, Vortex, & Aimpoint), and this is now my favorite range gun sight. The large window really helps to pick up your target quickly. I have a Leupold Delta Point on a CZ Shadow 2 that I thought provided a super view, but the Holosun is superior in many ways. I replaced a Vortex Venom on one of my range guns with the 507 Comp and could not be happier. The quality of the dot is much crisper, and the 507 offers a boatload of view options (2MOA, etc.) This is not an inexpensive sight, but if you are serious about your shooting, the 507 Comp must be considered. Buy one!

I’ve had the Holosun HE507COMP on my pistol for several months now and it’s been a fantastic upgrade over stock iron sights and many other red dots I’ve tried. The large 1.1″ × 0.87″ viewing window makes target acquisition fast and intuitive, and the sight picture feels very open compared to other optics I’ve used. The Competition Reticle System (CRS) is a real standout — I love having multiple reticle options (2 MOA dot plus 8/20/32 MOA circles) depending on whether I’m shooting close targets or dialing in at distance. It gives me flexibility for both practice and matches without feeling cluttered. Battery life has been excellent with up to ~50,000 hours and the Shake Awake technology means it’s ready when I need it without draining power while sitting on the shelf. The controls are intuitive and the lockout feature keeps it from changing settings accidentally. Build quality feels solid — lightweight yet rugged aluminum housing with IP67 water resistance — and it has held zero even after multiple range sessions. Whether you’re into competition shooting or just want a reliable reflex sight for everyday use, this one’s a great choice.

Great Optic and have had no issues with it. Big window size is nice. Red dot is clear.

You will be surprised how much faster you can shoot a Large window RMR sight.

Nice site, but the screws included don't fit a 2011 it seems. Needed M4 0.7 about 8.8mm and it doesn't come with any M4 0.7 in 8, 9, 10, 11mm. This is pretty annoying for a $400 site. I bought a Vortex XL Defender, and they included like 6 different screw types and sizes to fit basically everything. Luckily I had some of the right screws from that, but have to file them down to fit.

It’s like looking though a TV screen it’s so big! If you are used to micro red dots or even 407 size, this Comp version is going to wow you. Let’s you keep the dot in visible frame during recoil. The multi reticle gives you options galore.
