  • Top notch Optic
Size: One Size Color: Red 2 MOA Dot & 65 MOA Circle (HS510C)
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

  • Bright and Visible, Doesn't Lose Sighting
Size: 3.3 x 1.6 x 1.8 Color: Green 2 MOA Dot & 65 MOA Circle (HE5...
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

  • Excellent, almost perfect optic.
Size: One Size Color: 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 “shake to wake” feature. Can be left “on” for years. EoTech XPS2-0: Rated for ~500 hours with CRA123. Auto shutoff feature means that it may not be “on” 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

  • Beats RMR and Vortex dots. Best value red dot out there.
Size: One Size Color: Red 2 MOA Dot & 65 MOA Circle (HS510C)
I've had an RMR and a few Vorted red dots. The RMR had the dimming issue I resolved with an antiflicker plate and I loved it. The Vortex dots aren't sexy but they just work. I could punch a penny at 25 yards with both. This new Holosun however beats them all. The features, construction, and options put it above the competition at almost half the price. Perfect cowitness with the BUIS that came with my B&T GHM9. Took a considerable amount of left to right adjustment, but the up down was dead on. The shake to wake feature gives it true "Go Gun" status. No fiddling with buttons to turn it on. In a bad situation you don't want to have to try to turn one on when you really need it. Pulling it out of your bag will bring it to life and you're ready to rock. Autodimming is also a great feature my RMR and Vortex dots didn't have. Once enabled you will see a noticeable and immediate difference going from dark/dim to brighter areas. Works excellent outside. The feature is disabled by holding the + button for 3 seconds. This would be ideal if you're in a shaded environment and your target is outside in a brightly illuminated area. In the higher brightness settings you can still see the reticle when you point it towards the sun. You won't lose your dot in bright areas. The reticle options are also very hand. 2moa dot will help you plink pretty far down range and the larger 65moa reticle will give you fast acquisition at closer range. They defiently both have their place. And neither the RMR or Vortex dots offered multiple options. The battery life is supposed to be incredible. I haven't had it long to know, but all testing has shown you'll have years between battery changes. Keep in mind it does come with a spare battery tray so you if your grip has storage you can keep the included torx tool and spare battery with you when it becomes an issue. The solar feature is reassuring. Worst case scenario youre in the field or fight and the battery dies. If you are outside in the sun, or have enough ambient light the dot will still work. If SHTF and batteries are no longer available, you'll still be able to use it. The value, man.. It is just a no brainer. Half the price of an MRO or RMR. More features. More rugged design. The Alamaba Arsenal torture test includes, pouring water on it, throwing it 20ft into the air and letting it hit the ground, freezing it in ice, beating on it, and SHOOTING it with a shotgun, and it still held zero. The quick release mount also saves you an extra $150 if you were running other dots and allows for a perfect BUIS cowitness. Mine fit a little loose when I first installed it. I used the included tool and tightened the mount one turn and it clamped down with the force of an Amazonians thighs during Snoo Snoo. Absolutely solid now and still easy to release with the convenient latch keeper. The picture is incredible. The thinner profile sides and large viewing window give a natural feel and you're not chasing the dot around. No toilet paper tube EFFECT or black glob in the corner like with the Vortex Sparc AR. With boys eyes open you hardly notice the frame. You just see everything as well as a dot in your FOV. I will probably buy another one for my next Scorpion build. Can't imagine anyone coming out with a better optic for the money. ... show more
