Ive had a EOTech 512 for awhile now on one of my safe-queen rifles. I never sighted in the EOTech (never knew the proper procedure) but it seemed to be very accurate out to about 50 meters or so the times I have used it. It starts getting inaccurate around 100 yards
Few questions for the EOTech users in here: Do you use front or rear sights as a co-witness when you are shooting? If not, do you just keep the reticle as centered as possible when your shooting? I would think that if your eyesight angle to the reticle is even off by a degree or two, it could make your shooting inaccurate. Is this assumption true? And lastly, is there a write-up or tutorial somewhere on how to properly sight in the EOTech to 100-150 yards or so? Thanks |

Bore sighting an EOTech (or any other sights for that matter)
Take off your upper receiver, remove the bolt and carrier. Look down the bore (the big hole in the barrel), pick out a distant point of reference. Try to keep the "little hole centered in the big hole" while looking down the bore. The little hole is actually the front end of the bore and the big hole is the rear of the bore. You'll see what I mean if you you try it. Look though your EOTech, match up the dot on your sight with the distant point of reference you identified while looking down the bore. You will actually have to adjust the windage and elevation, don't just move the whole thing around. The EOTech dot reticle will look like it's changing position radically, but you'll notice that as long as you keep the optic in the same place and move your head around... the reticle stays centered on your target. Hint #1 Turn on your EOTech. Hint #2 Don't move your upper receiver around while you're adjusting your sight. This is to get you on paper (bore-sighting), continue fine-tuning as needed to get a zero that's acceptable to you. Hint #3 Adjust the sight elevation and windage to match up the dot in the EOTech with your point-of-impact (the bullet hole). Try to keep your shooting consistent while doing this. |

Wherever the dot is, regardless of its position in the window, to the front or rear sight, or to the gas giants in the solar system, is where the round will go when properly sighted in. Do you have the instruction manual that came with the EOTech? No I do not have the instruction manual, unfortunately. When I received the item, it was just the EOTech sight and nothing else |

EOtech, Aimpoint, etc., are designed for simplicity. If not, do you just keep the reticle as centered as possible when your shooting? Yes. They aren't built around long range accuracy. If you are able to aim center mass without covering the target with the reticule, you are using it within its intended range. I would think that if your eyesight angle to the reticle is even off by a degree or two, it could make your shooting inaccurate. Is this assumption true? The reticule does not have to be in the center of the optic to be on the center of the target. And lastly, is there a write-up or tutorial somewhere on how to properly sight in the EOTech to 100-150 yards or so? Sight it in as you would iron sights. Generally speaking, this is between a 25-50 yard zero to acheave a 200-275 zero. Once you find your short zero I would recommend dialing in your long zero if you actually have the room to do so. The bullet travels in an arch. The bullet will arch about 2 inches between the short and long zero in these perimeters. Thanks |

How in the hell do you do that?? Freakin computer whiz. |

Since I use a consistant cheekweld the dot will be pretty much centered, but it's not something I look for (or need). I would think that if your eyesight angle to the reticle is even off by a degree or two, it could make your shooting inaccurate. Is this assumption true?
That assumption is completely false. The whole point of RDS's (Red-Dot Sights) is that as long as you can see the dot and put it on the target you should hit. On a properly built RDS (like the EOTech & Aimpoint) where the dot is in the display doesn't matter. is there a write-up or tutorial somewhere on how to properly sight in the EOTech to 100-150 yards or so?
The instructions that came with your sight should tell you how to adjust the ponit of aim. They are also posted on EOTech's website. Zero at 50 yards. If your EOTech is mounted to the flattop it will give you a nice flat trajectory allowing you to hit beer cans from the muzzel out to 225 yards with a center of mass hold. 50y near zero with a 200m far zero is pretty much the optimal zero for an AR. |
