Does the magnifier enlarge the red dot's MOA or does it stay the same like a holograph?

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.

No this is a factory original product.

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.

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*.

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.

Mine came with both long and short screws
