I am looking at buying a magnifier for my 512...
I see mounts for magnifiers but listed in two hights. I assume the xps is higher and needs the elevated mount and the 512 does not require this higher mount right? |

Quoted:
I have the XPS magnifier...it came with a spacer...it absolute co-witnesses out of the box and with the spacer, it 1/3rd lower co-witnesses. I do have to say, the optic shifts the impact point a bit, so shots over 200 yards are all over the place. thanks! |

I run the Aimpoint Magnifier in a Larue Flip to the side mount behind an Eotech 512. I believe its the tall flip to side mount from Larue and it clears my Back up irons when the rear BUIS is folded down and opens with no problem when the Magnifier is flipped to the side.
It looks like it is a little high and not centered with the eotech window, but the magnifier adjustment screws took care of that and the dot is centered up in the magnifier. I have not noticed any POI shift with the magnifier? I shoot three gun with this rig out to 300 yds and its POI is the same with or without the magnifier. Make sure to use a small amount of lock tight on the mounting screw and it will hold zero much better and longer. DONT use to much or you will have to heat and hammer the optic off and take it completely apart. ask me how i know. It sucked Also watch your reticle when you turn on your sight. when it blinks its telling you to change your batteries. |

Out of curiosity, did you buy the $300+ 3x magnifier produced by EoTech, or one of the knock-offs? I have heard of the issues you mentioned with the cheaper knock-offs, but not with the EoTech produced 3x magnifier (which is not to say it hasn't happened). |

Then again im no science major. |

Then again im no science major. If it is just glass than why buy a $600 Leopold scope versus the $50 Wal-Mart scope? Cheaper made products are typically not as precise, don't use quality materials, don't have as tight of tolerances in their production, etc. That is why they are cheaper, because the manufacturer had to cut costs somewhere. I've been researching purchasing a magnifier for my EoTech and everything I have read says stay away from the knock-off cheaper magnifiers. Just my opinion though. |

I believe that if the lens on the magnifier is distorted, it will cause the virtual holographic reticles that the EOTECH projects to become somewhat displaced, changing the POI. |

I would agree about buying quality glass.. I can see where the glass may not be as clean or as crisp or even as magnified as a nice magnifier or in a scope all the internals that make it a scope. But how does a shitty piece of glass (just the magnifier) change POI on site that is not attached to it. i could hold saran wrap behind my Eotech and that wont change where the Eotech is pointing or its zero. i guess i just dont understand |

The magnification does not work for only a limited space infront of the magnifier. If it shifts the sight to the left it will shift the entire field of view to the left. |

Sounds like we need a physicist in on this discussion. My thought (and I'm no scientist, I'm just speculating here) is that what we are really talking about here is light waves and magnification of them. When you are on the surface of the water looking down at a fish under water there is a distortion of the light which causes the fish to appear in a slightly different location than it actually is. And with a telescope, the clarity of an object at distance is only relative to the power of the telescope to magnify the image. Perhaps the problem is that a cheaper magnifier lacks some of the clarity to magnify further objects (say out past 200 yards) and therefore everything is actually distorted. But the EoTech reticle is a hologram than tricks your brain into thinking it is projected downrange and on your target. Therefore perhaps it creates an illusion and tricks your brain into thinking the target, like the fish, is someplace it really isn't and your therefore holographic reticle is actually on target when it isn't? I think I just had a brain aneurysm trying to logically think about stuff way above my pay grade. |

However i would see the magnifier as the surface of the water and the hologram and the target below the surface of the water. So even though they are offset they are offset equaly. I know a physisist. Maybe its time to give him a call.. |

I have a 6.8SPC with a 517 Eotech and a less expensive Primary Arms( $100) 3X magnifier mounted on a Larue swing over mount.
I haven't shot the thing beyond 200yds but I haven't experienced any noticeable poi change when I swing the magnifier in or out. But I'm not doing bulls-eye shooting with the thing either.... |

Just curious, have you tested this in a controlled environment (or as controlled as possible) to eliminate other possible variables that could be causing your rounds to be off at 200 yards? |

Something interesting about the EoTech holographic reticle is that as you move your eye the hologram can appear to move yet it actually stays on target (even though it doesn't look like it is to your eye). So perhaps the magnifier is the water, your target the fish, but the holographic reticle is somehow its own factor? Just thinking out loud really. |
