Windage can be adjusted for by using Armourers Drift No1 ( small brass punch) and drift foresight towards the error. Or use the correct foresight cramp, (Armourers used the punch and hammer method as it was quicker). If the foresight needs moving more than 0.050" then you have an issue with the fit of the forend and you need to find someone with the correct skills to rectify this.
how do you contact terry?

Google is very efficient, failing that

Thanks for the info, guys. Thanks for the pics, Gaz.
Right, so turns out after years of assuming it was a pin holding the foresight in, turns out it's a punch mark. I assume to align the blade with the block.
Anyway, if I am to replace my blades, may I ask how? It's not like changing batteries, and can this be done at the range? If not there's gonna be a long time between blade changing and rezero'ing. I assume there's a magical, armourer's method to use? I don't really fancy just whacking the sights with something heavy.

A quick google shows there was a foresight cramp to adjust the sights under service conditions, so in the absence of that I think you may be reduced to a lump hammer and a bit of wood...

Place the sight block on a block of wood and using a brass drift and a hammer and just knock the foresight blade out. File the punch mark burrs flat and put a lower height foresight in. You will need to gently tap the new blade in.
A well known gunshop at Bisley sells blades for £2 each and will fit them for free if you feel that you are unable to do this task.
Bring the rifle to Bisley and I'll zero it for you and give you the correct height blade free of charge (you pay for the target hire).

And that is a complete rip off for the gullible. Individual blades should cost no more than £2 each. That is £14 for the complete set.

Many thanks for the advice, Steve. Thank you for the kind offer, i'm down my local range soon, I should really try and zero these rifles at 100 yards/metres before I do anything.

Either of those would be a simple solution.
Couple of things: If you buy just one sight, make sure its not too low (again, if you go to 'a well known shop at Bisley' they can advise you) other wise you'll have the opposite problem (which is one of the reasons I got a sight that was just a bit lower for my M96 and filed the rest) - The other thing; is that what Steve is saying about using a drift and hammer for zeroing the windage isn't as hard as it sounds...takes a bit of trial and error but is easily doable at the range...also one of those small hammers with the rubber/nylon ends makes the task easier and also gentler on the rifle.
