I have owned this little optic for about a year now. First on a rifle but now resides in my home defense shotgun. I have found this to be a tough well made optic that holds zero even through punishing recoil of a shotgun. I have had zero issues with the QD mount attaching to the picc rail of my firearm and once there it is rock solid. The reticle is crisp and clear even with aging eyes. The adjustments in illumination level is easy and is palpably visible. There is some blurring on the highest level, but this in no way makes the optic unusable at this level. The sighting adjustments are a little mushy, but you can feel each click. I was able to Ranger Wrap my 510c to match my A 300 and that was like icing on the cake for this tough little guy. One drawback is that it has an open emitter that could become dirty or occluded. After several range trips in dry dusty conditions, I have yet to experience a failure in function. This optic is a solid addition that you can depend on plus your wife won't kick you out after purchasing it!! ... show more

It just works very well. It's clear, bright, and the reticle is very visible. Highly recommend this optic. I dialed it in with a bore laser and was hitting with accuracy using 300 blackout AR pistol

    • Excellent, almost perfect optic.
Style: Red 2 MOA Dot & 65 MOA Circle (HS510C)
Glass Optical Quality/Characteristics Holosun 501c: Excellent – Glass adds almost imperceptible blueish color. The coating on the glass nearly completely blocks red laser light. EoTech XPS2-0: Excellent – Glass adds almost no color. Trijicon MRO HD: Good – Has almost imperceptible magnification factor (probably around 1.05x). As noted by other reviewers, it is possible to sometimes see a reflection of the emitter/circuit board. This reflection is only visible under unusual/momentary lighting conditions. Neither the magnification nor occasional reflection bothered me. Dot Quality/Characteristics Holosun 501c: Excellent – nearly perfect line/dot quality. Very cool ability to switch between a single red dot and a red dot surrounded by a 68 MOA segmented circle. EoTech XPS2-0: Good – but the center dot and the segmented circle is slightly fuzzy, like it is made up of a bunch of tiny, smudged pixels. Cannot switch to center red dot only. Trijicon MRO HD: Excellent – nearly perfect line/dot quality. Very cool ability to switch between a single red dot and a red dot surrounded by a 68 MOA segmented circle. Parallax Holosun 501c: Very good – almost no/very little perceptible parallax. EoTech XPS2-0: Excellent – almost no perceptible parallax. Trijicon MRO HD: Very good – almost no/very little perceptible parallax. Battery Holosun 501c: Rated at 50,000 hours with one CR2032 for dot-only, 20,000 hours for dot + segmented circle. Also has β€œshake to wake” feature. Can be left β€œon” for years. EoTech XPS2-0: Rated for ~500 hours with CRA123. Auto shutoff feature means that it may not be β€œon” if grabbed in the middle of the night. Trijicon MRO HD: 2.5 Years of continuous use of dot; 75 days of continuous use for complex reticle. Bulk/Field of View Holosun 501c: Largest viewing window, with several milimeters of additional height over the XPS2-0. Thinner/smaller metal casing, resulting in near-perfect field of view. No visible battery compartment. EoTech XPS2-0: Large viewing window. Slightly thicker casing than Holosun, but forward battery placement allows for otherwise unobstructed view (i.e. compared to Aimpoint PRO). Trijicon MRO HD: Smaller tubular viewing window, but still easy to use with both eyes open. Slightly bulky control wheel on top (also holds battery). Construction Holosun 501c: Made in China. Overall seems well built. Quick Detach level is relatively thin metal and could break or bend if dropped while half-way open. Otherwise, seems like it could hold well through hundreds of QD cycles. LED emitter is not fully enclosed and could theoretically be damaged (but very unlikely as it is recessed). EoTech XPS2-0: Made in USA. Seems very well built. Trijicon MRO HD: Made in USA. Seems well built. Mount is not quick release and requires unusual keyed tool to attach/detach with screws. ... show more

I put this on a 12 gauge KSG. I had the gunsmith sight it in for me, and its dead on... even at 100 yard slugs! Obviously, this speaks to the gunsmith's ability more than the sight. However, even after nearly 50 slugs, 50 buck shot, 200 birdshot shells, the sight is still perfectly on target. The dot is also extremely crisp, and being able to switch between single dot, dot and cross, and just cross was a neat surprise! Well worth the money, and frankly I won't be buying EOTech again after this legendary performer. ... show more

Review Image by John John
It has been through about 370 rounds (About 250 were bird load) in 2 days. This HE510C-GR is great overall sight. Easy to use, easy to quick mount/QD (If it ever fails). It has an Eotech style reticle which is very crisp and clear; I'm settled with the 65MOA circle only for now since it's mostly for bird and 00 bucks. Most of my other sights are green(ACOG and RMR) because I can pick up that green reticle super quick and easy. No, it doesn't lose contrast when aiming at trees, I was able to hit two skeets this afternoon when they fly into the green leaves, and the range is also surrounded by trees. The fact it is solar and battery powered are great features for my use, and the auto on/off and brightness make this sight very smart. The auto brightness only goes from your setting to the max brightness is so thoughtful (which means I can change the minimum brightness anytime). And push both buttons can turn it off if I have absolutely no need to use the sight and push anyone to awake it to the previous setting is just convenient and will help extend the super long battery life. Shotguns in general are pretty rough on the sights, I had this sighted yesterday and it held zero just fine. The titanium hood has already protected the Al body from a few light scratches. The mount is pretty solid and I did try to QD it a few times for the training and it returned to zero no problem. This sight let me use the middle position for the M4's butt stock which is nice(as the picture is shown), the full length of pull is kind long for me, the middle position gives me less felt weight and shorter overall length (which makes the aim faster and less strenuously). It just let skeet shooting more fun and relaxing, and I can teach someone totally new to shotgun super quick on how to shoot it. I mean, shoulder the gun, both eyes open, put the circle on your target, pull the trigger (safely, of course), what can be more straight forward? Especially when you have a Benelli M4 with this sight? My friend(new to guns) started hitting flying clay within 5mins from I handed him the shotgun while teaching him how to use it. ... show more
