Red dot zeroing

[jeepnuts]

The other day I shot a friend's AR rifle, a flat top with a SiG Romeo red dot sight mounted on it.

He does all his shooting at 5 to 15 yards to simulate combat conditions in and around his home. So, he had chosen to zero the rifle to be dead on perfect at 7 yards.

Well at 25 yards it was quite high (but still usable if you knew where to hold well below the target).
But at 50 yards we determined it was shooting about 4 feet high and 100 yards it was hitting 8 feet above the point of aim. This was ridiculously high --it basically made the weapon unusable at those distances.

That’s what happens when somebody has zero clue what they’re doing.

I use 50 yards for my AR's, which means 1.2" low at 25 yards if I have to use an indoor range for the basic zero. Keeps me within like 5" or so of POA from 5 yards out to 300 yards, I think. More than adequate for anything I am ever likely to use those rifles for.

My Extar EP9, I zeroed at 15 yards... That has me at 3.5" or less of POA from up close to 100 yards which is the practical limit of a little 9mm PDW...

I'm weird and zero all rifles at 100. Easy math on my head and I can pick up any rifle, know my zero, and know my dope at different ranges.

I don’t think this is weird at all. Reckon I’m weird too.

I was going to try these the next time I went to the indoor range.
