Me and a buddy were sighting in our ar's yesterday and we just couldnt get his on paper.  The first group was 6+ inches high at only 20 yards and after adjusting the front sight to the maximum it would go he still was 4 inches high at 20 yards.  He has a spikes upper with a diamondhead VRS-T free float rail with troy micro battle sights.  Everything was nice and tight and intalled correctly.  We checked the package the sights came in and they were meant for same plane application which is how he had them.  Any ideas?

Make sure the rear sight is in the farthest back position on the upper receiver (closest to the charging handle) and the front sight is positioned in the closest spot to the muzzle

They are as far apart as possible

hmm...strange. Visually does the rail appear to be exactly the same height as the upper receiver?
here's a quote I found from someone with a similar issue 2 years ago...I would tell your buddy to call Troy and tell them his problem.

I am running them on a 20" P308. I had an issue with the front sight though. It is my assumption that Troy put front sites from their standard sights in their micro sights- the result being that the front sight will not screw in far enough to obtain a 100 meter BZO. After taking a smidgen of metal off the top of the front sight blade, I was good to go.

This is the build it yourself forum. I would post in the optics & sights forum. Move back to 50 yards & report back.

The rail does seem to be good, didnt put a straight edge on it or anything but visually it seems good.  He may have to contact Troy and see if this is the problem.  Thanks

He did build the weapon himself?

The micro sights are not made for the AR. They are made for a rail higher then the AR. You can use them but it's hard to get a good site picture with them. Could be part of your problem. ymmv.
