    Posted: August 24 2010 at 6:43pm
Hello all, I have a No 4 Mk1 that I got awhile ago and when I went to shoot it, I noticed that the front site had moved far over to the left.  I fiddled with it and found that it slides easily and is not anchored solid at all.  How to fix this.  I thought of trying to sight it in and then lock tite it but that sounds like it would not work.  Any thoughts on how to stake the site so that it wont move?  After sighting it in of course.  Thx

Some No 4  frontsights are secured with a screw with a reverse slotted head. It willl have a blade standing proud.  It can be tightened (or loosened) with a special screwdriver that has a  groove cut in th eend.  Numrich sell a  tool with that tip on it or you can make one using an old screwdriver and a dremel.

If there is no securing screw the sight base should have a "cut" in it, visible from below if you remove the blade.What you can do is to slightly widen the slot's width with a screwdriver & hammer.

Another possibility is that you have the type of blade for the locking screw in a body without a locking screw,  these don't have a slot as the screw does the locking. If that's the case you'll need to replace the blade with the correct type, making sure to get the same height.

If it is the type without the locking screw, you can peen the bottom of the dovetail with a centrepunch, replace the blade and it will be tight.
you dont need a lot of heavy peening, a few dimples and try it until its tight.

A bit of silicone caulking in the dovetail just before you shoot will allow you to set the proper windage. It'll take about 12 hours for it to cure completely, but at least then you'll know where the front sight blade is supposed to be.

Securing the foresight with an adhesive is ok if you dont want to change your load.
You really need to repair it so that you can adjust the sight if you change loads.

I have the same problem with my No4 Mk1, FAZ, 1948.  The front sight does not have a lock screw and I can move it with my fingers.
 
When you wrote "really need to repair", did you mean simply peening the dovetail so the sight fits tightly?  Or something more involved, perhaps?
 
When peening, I leave the front sight in, no?
 
Cheers

Remove the sight blade from the block and using a centre punch, put a couple of light dimples in the bottom of the dovetail, just enough to lightly raise some metal around the dimples.
then it is simply a matter of tapping the blade back into place.
Make sure you support the bottom of the barrel well when doing this, they are not hard to bend.

Makes perfect sense!  Thanks so much.  An easy fix.
