    I'd like to tinker with the BUIS on your upper. I can't get my POI up high enough, and my FSP is buried in the sight tower. The rail is mounted straight as an arrow. We need to shoot.

    Markm is this with the ELW upper?
    It is from the construction of underground FEMA camps. I can't say more because there a guy parked in front of house in an AMC Pacer. He is acting like he talking on the phone, but I know better.

    I have to sign off now & put my laptop in the microwave.

    Yeah... I'm almost never running the BUIS so it's not been an issue. But I think the Rear app is low. I mounted it in front of a cut down carry handle, and the small app is visibly lower than a USGI app when bottomed out.

    I was all but certain the back sight was low until I tried one of the KAC USMC flip ups. It matches the Diamondhead pretty closely. But I think I can remember having to spin that KAC sight up to get it into reality.

    I don't have a way to check the Front sight accurately.... so I'm going to have to move irons back and forth to see if I can conclusively find out which sight isn't playing well. I can shoot great groups on paper with the sights... just that the POI is too low.

    Interesting, the rear sight and Aimpoint on my Fluted ELW upper needed to be adjusted pretty far to the left. I can also shoot pretty good groups with mine.

    I am still worried I tweaked the barrel putting the comp on, but the windage is not maxed out, and it holds zero and shoots fine.

    I ended up shooting AGAIN yesterday. I wanted to stay of the range this weekend coming up... but now I have an un-zeroed gun. It's going to eat at me all week.
