Thanks for that! I was looking at earlier models and how their sights are attached. What i was trying to nail down was whether the difference in sights was the cut out being on the barrel or the sight. I think, based on the few pictures I could find, the rear sights on the earlier 340/350 target models have the relief cut into the barrel for installing the sight, vs the sight having the relief cut, like the one you pictured.
It seems as though there was a direct carry over of the set screw retained sight from the previous model, but the relief cuts are different.

I've install the 340B sight on a ES350B barrel, it is possible (it could slide both for- and backward. It is maintain in the barrel grooves but there is a lot of lag.
I've tried to install a ES350B sight on the ES340B grooved barrel. It is fitting in the barrel cut out but could not slide neither to front nor rear.

Perfect, that is exactly what I was looking for. So the barrel on these models must be cut for clearance to install vs the later B series having the clearance cut on the base itself.
I'm not a machinist.
On Es340N and Ms420N, the rear sight is sliding in the grooves first in the receiver continuing in the barrel grooves.
I guess that these grooves were machined in the receiver and barrel in one operation after receiver and barrel being assembled.
There is something different in barrel or receiver between grooved and not grooved in the N series.
Have a look here at the receiver-barrel junction : https://www.k98kforum.com/threads/t...2-rifles-and-the-grooved-es-340b.47170/page-2 post #30

The first Mauser B series .22 rifles and the "Grooved" ES 340B
Just a picture showing what you explained : from top to bottom ES340N, ES350N and MS420N grooved barrel. I just realize that the DRGGM is missing on the ES340N barrel The next one from top to bottom ES340B Grooved,, ES340N Grooved, ES350N and ES350B (if not on the picture, i got the numbered...

This post probably shows it best. So for the ES340N, with the grooved barrel and set screw retained rear sight, the rear sight must be slid from the rear of the receiver into position?

On the following picture as I didn't wanted to remove its rear sight again I've tried to show this with the ES340B rear sight.
The B rear sight is passing on the N receiver but could not enter into the barrel grooves (depending the direction it is inserted...)
