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 ## Frequently Bought Together - HOLOSUN HS510C & HM3X Combo Multi-Reticle Circle Dot Open Reflex Sight w/3x Flip-to-Side Magnifier 510C-HM3X - Magpul Rifle Bipod Gun Rest for Hunting and Shooting - Magpul QD Sling Swivel --- ## 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.be/products/177475890-510c-and-hm3x-combo-red-green-multi-reticle-circle-dot](https://www.desertcart.be/products/177475890-510c-and-hm3x-combo-red-green-multi-reticle-circle-dot) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-08-15*
