k-31 front sight adjustment

I have a K-31 and would like to know if there is any special tool to drift the front sight to adjust for windage. Do I simply take a brass drift and move it with some gentle persuasion? Help before I do some harm! reindeer

Yes they do...I am trying to find a picture for you. What it basically is, is a square clamp with a fine threaded screw for pushing the sight fore or aft. Notice your K-31 front sight will be angled(Fr-R, aft-L) The sight will also probably be 'staked' to the original shooters likes. Back when I was looking at buying one they were about 30 or so bucks. Now they seem to be 'collectable' therefore much more expensive.
I did what you were worried about and used a brass drift punch and gently moved it to my zero. The metal in them is pretty hard and therefore won't deform unless you use a bunch of force. Just be gentle with it and move it in little amounts once. Measure from the original stake mark while aiming and that will help get you close to how far you need to move it. -good luck
Or you can tap it with a brass punch lightly.
Aren't they amazing? I just took mine to the range a couple weeks ago and shot my handload for it at 100 yds. I shot several 1-3" groups then decided I better settle down and show the guys just how good these K-31's really are. I held the right corner of the front sight post on the bottom left corner of the square bullseye. When I finished I had four inside 3/4". But, I pulled one an inch away from the group. Still a good group from a rifle that looks more like it might win an "Ugly Betty" contest.
First, I must apologize as these kind of groups are always possible from the rifle. I did not do my part for the first groups. When I got serious the rifle did it's part and I, with one exception did mine. The result was an outstanding group that can typically be had with these rifles. I have typically found they shoot at that MOA at 300 as easily as 100. Provided you have the right target to see at that range.
You have to admire and wonder about what this rifle brought to the shooting world. First the straight pull, which at first seems awkward, but in the end feels solid. And then the cartridge size. It starts out as the standard Swiss 7.5x55 dimensions. Then the case ends up looking something like an Ackley case...Things that make you go hmmm.... Nothing bad against Ackley if it's true, quite the contrary. He did something spectacular with the spent case...and others.
