| Are these parallax free? I was shooting at 50 yards yesterday and I couldn't seem to hit the broad side of a barn. |

Are you just zeroing it? Trying too. I was gonna use it for the hunt but I gave up and put my scope back on. Do I have to have the same cheek weld and sight picture each time? I hit the target twice at 50 yards and then proceeded to miss the entire target about 10 times. |

If you have irons that are zeroed then putting the dot on top of the front post while the irons are lined up is a good place to start. If not removing the upper and bore sighting is my preferred way to zero. If you are bore sighting remember to move the dot in the opposite direction you want the POI to move. You can also zero at a shorter distance then move out. At a shorter distance shoot for groups before you move out. If it holds a group then you know the sight is not drifting. If the dot is anywhere near the center of the window then parallax is not the issue. Let me know how it goes. Marshall |

Alright, I will try it out at the range and see what happens. It may just be that I was sitting on the back of a truck and it was windy. I don't know. I tried lining it up with irons to no avail. I might try at a shorter range to see what happens. If the irons are zeroed then putting the dot on top of the font post when looking through them will get you close. It has to because the dot and irons are looking at the same spot. The relationship only works when the irons are lined up. That is a good place to start but I always then fine tune the red dot independently. |

I really want to go with a lower 1/3 but if the mount is meant to be used as absolute I can see why I would have a problem. |

I really want to go with a lower 1/3 but if the mount is meant to be used as absolute I can see why I would have a problem. Cowitness can be confusing. It is not relationship of the dot and irons. It is where the irons line up in the sight window. Our mounts are lower 1/3. With both absolute and lower 1/3 if the irons and red dot are zeroed at the same distance the dot will sit on the front post when you look through the irons. At short distance where there is some parallax they might be a little off. Also your eye might have a little trouble knowing what to line up on so that is why I suggest fine tuning the zero independently.

I can't stand the fact that the iron sight moves while I move my gun. It feels like I need to have the SAME sight picture each time otherwise it would be off. If you understand what I am saying. I wish I didn't have a FSB. It would make it easier IMO because I wouldn't see the front iron post at all. |
