I went shooting the rifle her yesterday and I must say it regulated fine and it didn`t blew up. Thank goodness!!.

However the line of sight and the line of the bulletpath doesn`t meet at any distance.
Shooting at 50meters the rifle printed 40cm below point-of-aim.
To prove what I suspected I went to shoot at 100m and the rifle printed 70cm below point-of-aim.
The line of sight versus the centerline of bore is orthogonal.
The further distance the further apart!.
I doubt the gunmaker has never used the original sights to regulate the rifle with.
Yes the rifle regulate but not in horizontal line with the sights.

Solution: The front sight must milled 3mm down and a new slot milled out for the sight-insert. Thankfully I know someone who can do it.
I was about to get itchy nerves.

The ejectors work perfectly not throwing the cases 2miles away but merely releasing to an easy grab.
