Review: Excellent - Holosun is a fantastic optic, Yes it is made in China and they are making a very durable and top of the line product. Excellent sight picture ,very clear and durable optic, I shoot a lot and I believe this is my eighth one I have purchased for the collection of rifles I have, I own EOTECH and many others, there is nothing more durable than EOTECH but this comes pretty close when you look at it has solar so you really never worry about it working, shake awake, fog and water proof, night vision capabilities, reliable to zero every time, don’t worry about the battery and don’t forget to buy a cheap cover to go with it, you really can’t go wrong with any of the Holosun line Review: Best quality optic for the money - I waited almost a year after buying this to do a long-term review. To all the haters who told me I NEED to buy a top-tier optic like an Aimpoint or an Eotech and this isn't reliable, I can honestly say this optic is very sturdy and reliable. I've ran this in several competitions now, it's been thrown around in the back of a truck, been drenched in water, and been attached to a carbine with almost a thousand rounds of recoil and it has held zero and still as reliable as day one. I can hit 1/3rd ipsc targets at 100 yards without any problems, and I'm not exactly good. Granted, I don't abuse my equipment all that much, I'm not going to be taking this thing to war or running over it with a truck just to prove a point, but for 99% of "normal" applications this thing is rock solid. I shopped around a lot before buying this, compared against other brands, I get less "star burst" with my astigmatism compared to other brands of red dots (specifically the Sig branded ones are bad for my eyes), the optic is clear and the illumination is plenty bright for bright outdoor conditions with plenty of brightness settings for any situation (fwiw, the Vortex optics IMO don't have enough brightness settings, and don't get quite bright enough for direct sunlight, but an etched reticle can fix that problem). Holosun is the real deal. I might buy another one soon. ## Features - ADVANCED TECHNOLOGY: The Holosun HS510C New advanced technology LED allows up to 50,000 hours of operation on one CR2032 battery. - PROTECTIVE TITANIUM ALLOY HOOD: The Holosun HS510C Circle Dot Scope with 3 Reticle Options is waterproof down to 1m and durable enough for even the heaviest calibers. - COMBO SET: Includes Holosun HS510c Reflex Sight, Holosun HM3X 3X Magnifier and a protective storage case. - PROTECTIVE STORAGE CASE: Includes protective storage case so you can keep your Holosun items safe at all times. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0793T3WP4 | | Best Sellers Rank | #7,972 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #27 in Gun Sights | | Brand | HOLOSUN | | Brand Name | HOLOSUN | | Color | Red | | Compatible Devices | Firearm | | Customer Reviews | 4.8 4.8 out of 5 stars (4,602) | | Date First Available | January 1, 2020 | | Global Trade Identification Number | 00605930624991 | | Included Components | Holosun HS510CFDE: Fde Housing, Red Multi-Reticle | | Item Dimensions LxWxH | 3.3 x 1.8 x 1.8 inches | | Item Package Dimensions L x W x H | 4.69 x 3.66 x 3.03 inches | | Item Weight | 4.94 Ounces | | Magnification Maximum | 1 x | | Magnification Minimum | 1 x | | Manufacturer | Holosun | | Material | Aluminum, Titanium Hood | | Model Name | 510C-PAR | | Mounting Type | Quick Detach Mount | | Night vision | No | | Number of Items | 1 | | Package Weight | 0.39 Kilograms | | Part Number | HS510CFDE | | Product Dimensions | 3.3"L x 1.68"W x 1.78"H | | Reticle Type | 2 MOA dot with 65 MOA circle | | Size | 0.91 x 1.26" | | Sport | Hunting | | Style | FDE | | Suggested Users | unisex-adult | | UPC | 605930624991 | | Warranty Description | Limited Lifetime Manufacturer Defective Warranty | ## Product Details - **Brand:** HOLOSUN - **Color:** Red - **Compatible Devices:** Firearm - **Item Weight:** 4.94 Ounces - **Magnification Maximum:** 1 x - **Magnification Minimum:** 1 x - **Material:** Aluminum, Titanium Hood - **Product Dimensions:** 3.3"L x 1.68"W x 1.78"H - **Sport:** Hunting - **Style:** FDE ## Images ![510C Multi-Reticle 2 MOA Dot & 65 MOA Circle Open Reflex Sight - Solar FailSafe Shake-Awake, 12 Settings - Red/Green Reticle - Image 1](https://m.media-amazon.com/images/I/41XltHB+TVL.jpg) ## Available Options This product comes in different **Color, Style** options. ## Questions & Answers **Q: How many reticle option can we choose from this model?** A: The HS510C has 3 reticle options: 2 MOA single dot, 65 MOA circle only, and dot and circle together. Hope this helps. **Q: Can you use this red dot on a Springfield xdm osp Pistol?** A: No this is a carbine/rifle sight look at the the 407/507 **Q: Is it water and fog proof and will it set a Browning silver slayer real?** A: The HS510c is IP67 rated. Complete protection against ingress of dust and airborne particles. Protection against water and liquids, up to and including immersion in up to one meter of water. It looks like your Browning does not come with rails therefore you just have to add a Picatinny rail mount. Hope this helps. **Q: Does the solar cell recharge the battery?** A: No. But it doesn’t use the battery if it has solar. Been using the same battery that was in the unit when I bought for more then a year now with no problems and I don’t use the solar settings very often. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent *by K***9 on November 22, 2025* Holosun is a fantastic optic, Yes it is made in China and they are making a very durable and top of the line product.

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!! ## Frequently Bought Together - HOLOSUN HS510C-FDE-R Red Multi Reticle, Open Reflex Sight, Solar, Shake Awake - HOLOSUN HM3X-FDE 3X Flip-to-Side Magnifier w/QD Mount HM3X - Protective Case Scope Cover for HoloSun 510c, Optics Red Dot Lens Rubber Sight Dust Cover for Holosun HE510c-GR Elite --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.at/products/58810603-510c-multi-reticle-2-moa-dot-and-65-moa-circle](https://www.desertcart.at/products/58810603-510c-multi-reticle-2-moa-dot-and-65-moa-circle) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-04-23*
