- Reviewed in Canada on April 29, 2020Verified PurchaseI bought this for my 45/70. I was a bit worried about the recoil but after some research I found out that this red dot can handle a lot of recoil. The sight is very clear, reticle is nice and crisp. I would buy again.
- Reviewed in Canada on April 1, 2023Verified PurchaseI have owned at least 8 Holosun red dots and have been happy with all of them. The HS510C is no different.
I'd also like to give koodos to SRS Tactical, their service is top notch!

5.0 out of 5 stars Outstanding red dot.
Verified PurchaseThis is just an awesome red dot. Super easy to install, love the quick disconnect. Nice big clear glass and your choice of dot or circle or both. Easy to sight. Long lasting battery with wake function if sight is moved. You will love this sight. Great price for an outstanding red dot!

5.0 out of 5 stars Excellent, almost perfect optic.
Verified PurchaseGlass 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.

5.0 out of 5 stars Top notch Optic
Verified PurchaseI 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!!

5.0 out of 5 stars Worth Every Penny
Verified PurchaseThe old adage, "You get what you pay for" holds true for this sight. I really tried to find a lower priced sight that would be "almost as good" as this sight. I'm not a fan of overpaying for something that's a couple of percentage points better. I believe that I will never regret paying the extra price for this sight. The construction of it is exceptional. I purchased it for my Ruger PC9 and it sits perfectly! The large screen (glass) is super easy to sight. I like the built-in solar array to support the battery (it doesn't charge the battery but the sight runs off of it instead of the battery in bright light). I also like the automatic mode where the unit changes brightness depending on the ambient light and turns off after 10 minutes of inactivity. Then is wakes up when it senses movement, and it doesn't take much. I have red dot sights on my handguns as well and I've always like them. This sight has a 65 MOA ring that can be selected along with (or by itself) the red dot making it extremely easy to locate even in high stress situations. You won't be disappointed that you purchased this sight. Although you might have to eat beans and wieners for a few meals to pay the extra price. Do it. You'll be glad you did in the long run.
