| I was talking to someone today about placing an Eotech, particularly the model that comes boxed with the M&P 15. I think that generally you want it as far forward as possible on the receiver to put the reticle out in front of you where he suggested it go back like a scope. To me having it too far back makes you have to put your eye too close to the optic, that and to me the model we were discussion looks like it is cut to be able to be placed over the handguard. I don't know I have zero experience with an Eotech as I do not have one and the online instructions I guess say it but what is the consensus. |

Wherever you feel most comfortable with it. It doesn't matter how close or how far it is, it will still operate as intended. This. I prefer as far back as possible (w/o affecting balance), maximizing FOV through the optic to make it more forgiving of sloppy cheekweld when shooting from awkward positions (YMMV). Tomac |

As stated - wherever you feel comfortable with it; however, things to consider:
- Balance: Putting it towards the middle helps my rifle weight be distributed evenly - Buttons: On some models, it's hard to hit the buttons if they are backed up too close to fixed / deployed folding irons rights |

With a big optic like an Eotech it does not matter imo, but with a small optic like the Aimpoint Micro then I would say mount it forward at the end of the receiver. ETA: People do like the micro farther back for odd positions, but I have not tried that yet and have not had any issues with it forward in roll over prone.

It seems with he Eotech XPS series notably, in all the pictures they have it as forward on the receiver as possible. |
| Well one thing and I have been searching for an image of it but cannot find one from the right angle it seems like the model that comes with the M&P anyway seems to have a curve under the battery compartment to allow it to be mounted at the farthest forward postion on the receiver and have the battery compartment over the handguard. |

My older ones have this feature also. I like to mount mine as far fwd as possible while still on the receiver. It makes it easier for me (not sure why) to remember to keep both eyes open. |

Well to me it looks like if you have it right up to your eye it is harder to not instinctively close one eye. If it is out on the receiver more it places the reticle more out in front of you so it easier to defocus the actual unit and look through it. |
Definitely not as far back as possible  . There isn't any issue with eye relief and FOV isn't really an issue considering you keep both eyes open (meaning the further back the optic is, the larger it appears so the more it will block your FOV). Also, the further up the optic is on the rifle, the faster you can pick up the dot as you bring the rifle up... which means the better you can anticipate snap shots. As far forward on the receiver as possible is what i do. Decent placement and good balance.

As far forward on the receiver as possible is what i do. Decent placement and good balance.You're contradicting yourself. Regardless of whether the optic is mounted forward or rearward, situational awareness remains unchanged as long both eyes are open. However, the further forward you mount the optic, the more critical eye placement is for acquiring the reticle. This is where FOV through the optic (which has nothing to do w/SA) becomes important as the greater your FOV through the optic, the faster/easier it is to acquire the reticle and the more forgiving it is of sloppy cheekweld. Place your optic at the far end of a table then bend down and see how long it takes to acquire the reticle. Then place the optic at the end nearest you, bend down and see how long it takes to acquire the reticle. The results will speak for themselves. Tomac |

Put it far back. The reticle is easier/faster to find. No drawbacks. Except that all the tactical dorki will berate you on here saying that's not what Costa does. Seems like we should all just compromise and put it in the middle. That's why im going to do when I get home in a couple months to my Eotech that just arrived. |

Tomac Great then why does the manual online say to mount it as far forward on the receiver as possible??. |

Tomac You DO know we are talking about a "red dot" , right? You do know an Eotech is not technically a "red dot" right?. The reticle of an Eotech is a dot inside a circle with almost a crosshair going through that circle. |

Everyone needs to find the location that works best for them. Personal experience has led me to place mine as far back as possible (YMMV). Tomac |

The FOV thru the window isn't really much of a factor since it is your total FOV with both eyes open that is going to be important. If the FOV thru the window was so crucial ppl would never use Aimpoint T-1(s). I guess it is whatever you are used to and works for you. I have always been taught to keep it somewhat forward |

I have always been taught to keep it somewhat forward To each his own, I don't believe there's a single 'right way' any more than there's a 'perfect optic for all needs' or 'perfect rifle for all needs' (if there were, we'd all be using them...  ).
However, if you have access to a 30mm Aimpoint and an Aimpoint Micro, try this little test: Place the Micro close to your eye (say appx 3"-4") and note your FOV through the optic as measured against a wall or terrain details. Repeat w/the 30mm Aimpoint held the same distance from your eye. Surprisingly, the shorter OAL of the Micro appears to compensate for the 30mm's greater diameter, resulting in appx the same FOV through both optics. Tomac |
