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.
