Hi Peter, sorry to post this again , I should have explained instead of asking you to run all through the butchery thread again.

The problem with low mounted rear sights is probably genuine and probably comes from the no1mk6 rifle having a different rear sight set up from the no4 rifle, instead of a spring and plunger under it they seem to have a spring and ball, as per the no1 mkV. As the sight shape is not no1mkV but no4 style it's gone unnoticed here that the underside is shaped differently for that ball.
I've been trying to get a rear sight to work on my mk6 for sometime. It mounts but will not pivot due to being about .070 lower in the axle compared to my 1955 no4.
I bet our earlier friend with this problem has an A marked rifle.

But in addition to this I just realized what you'd said in your last post, that this affect the front sight greatly, and on this I can only agree and wonder just how the armorers solved a front sight post that had to be .070 lower, is there room just to grind the post down? ...and, I suspect plenty of A rifles lost their original non standard spring and ball pivoting sight over time, what did the armorers do with a non pivoting sight, bung on a 300/600 and leave it fixed, which is how mine came? (Although that would have meant it shooting low)
