So I used a cleaning rod on my 10" barrel. Found that the barrel alignment to the rifle was off. By 14" out from the muzzle, the bullet path was almost a cm down and a little to the right.
This makes since now because when Id keep my scope the same but switch distances from 25yds to 50yds. It would drop more than it should and go right.
All this time I thought it was a scope issue.
However Im using and Aero ultralight single unit. So I was frustrated thinking the upper rail wasnt straight.

So anyway, Im using tacticool barrel nut and carbon ultralight handguard.
Wondering if its possible when I put the barrel back in, it wasnt perfectly aligned?
Wouldnt the barrel nut align everything?
Thanks for the help!!!!
Marry X-mas!!!!!

Take it apart and put it back together again and see if things are the same. Maybe you don't have a nice flat surface for the barrel nut adapter to align with
