Review: Great product - you may need a 510-C spacer for AR platform - Great and solid product. Reliable, great combo. Great case and form fitted. Quick mount is fantastic, of course. The one thing i do not understand is that for an AR this is absolute co-witness (1.41 inches) and i have to push my face into the stock for alignment. There are included1/3 Co-Witness Spacer for both the red-dot and magnifier with the required screws. For the combined price and how solid this product is with quick release picatinny and along with the case - this is a great product. I may purchase another so that i do not fiddle with absolute zero between two different rifles when at the range. ## 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. - EASY USE: The reticle can be switched between a 65 MOA circle with 2 MOA dot, a 2 MOA dot only, or a 65 MOA ring only at the push of a button. Better yet, the same LED projects both reticles, so no re-zeroing is necessary. - 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 | B081DCD2K7 | | Aiming Scope Sight Pin Size | 1 millimeters | | Best Sellers Rank | #14,623 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #27 in Gun Sights | | Brand | HOLOSUN | | Brand Name | HOLOSUN | | Color | BLACK | | Compatible Devices | Rifle | | Customer Reviews | 4.8 out of 5 stars 1,084 Reviews | | Eye Relief | 7 centimeters | | Included Components | Lens Cloth, Riser, Tool | | Item Dimensions L x W x H | 3.3"L x 1.8"W x 2.31"H | | Item Weight | 4.96 ounces | | Lens Color | Red | | Magnification Maximum | 3 x | | Magnification Minimum | 3 x | | Manufacturer | Holosun | | Manufacturer Part Number | 510C-HM3X | | Material Type | Aluminum, Titanium Hood | | Model Name | 510C / HM3X COMBO | | Mounting Type | QD mount | | Number of Items | 1 | | Number of Packs | 1 | | Objective Lens Diameter | 32 millimeters | | Product Dimensions | 3.3"L x 1.8"W x 2.31"H | | Product Style | RED RETICLE | | Reticle Type | Circle Dot | | Sport | Hunting | | Sport Type | Hunting | | Style | RED RETICLE | | Thread Type | UNC | | UPC | 605930625714 | | Unit Count | 2 Count | | Warranty Description | Limited Lifetime Manufacturer Defective Warranty | ## Product Details - **Brand:** HOLOSUN - **Color:** BLACK - **Item Weight:** 4.96 ounces - **Magnification Maximum:** 3 x - **Magnification Minimum:** 3 x - **Material:** Aluminum, Titanium Hood - **Objective Lens Diameter:** 32 millimeters - **Product Dimensions:** 3.3"L x 1.8"W x 2.31"H - **Sport:** Hunting - **Style:** RED RETICLE ## Images ![510C & HM3X Combo RED/Green Multi-Reticle Circle Dot Open Reflex Sight w/3x Flip-to-Side Magnifier 510C-HM3X - Image 1](https://m.media-amazon.com/images/I/61-akSNwl5L.jpg) ## Available Options This product comes in different **Color, Style** options. ## Questions & Answers **Q: Does the magnifier enlarge the red dot's MOA or does it stay the same like a holograph?** A: Magnifiers always enlarge the reticle. With holographic technology like in EOTech, the central dot can be made small enough (~0.3 MOA) that it remains smaller than human eye resolution even after it's enlarged 3x. This, however, is not a holographic sight but a red dot. The central aiming dot here is 2 MOA large *before* magnification, so it does get proportionally larger with a magnifier. The flip side is that the reticle is crisp, and battery life is measured in tens of thousands of hours, not in hundreds. **Q: Is this a knockoff?** A: No this is a factory original product. **Q: Does it flip over to the left or to the right? It looks left, which would put it in front of your left eye when shooting eith both eyes open.** A: I’m fairly certain that it can be switched based on your preference, mine flips to the right. It can also be setup to flip 90* or 135*. **Q: Did the riser come with longer screws? I have longer screws for my magnifer and it mounts fine but the optic came with the same length screws.** A: Mine came with both long and short screws ## Customer Reviews ### ⭐⭐⭐⭐⭐ A game-changer for anyone in need of a versatile and highly effective optical solution *by A***M on October 19, 2023* The HOLOSUN HS510C & 3X Magnifier Combo, featuring the HS510C red dot sight and the HM3X magnifier, is a game-changer for anyone in need of a versatile and highly effective optical solution.
