Looking to buy/borrow K31 front sight tool

[C.N. Double]

I know there are some K31 owners out there. I need to adjust my front sight. I know there are replacement rear sights with windage (BAMM legal?), but I'd rather keep this one original. I checked a few retailers, but they all seem to be out of stock.

 

Is there one out there I can buy or borrow until I get my adjustments made?

I've never used a sight adjustment tool.  I used a brass punch, bumped the sight where I needed it, then put a mild stake on it with a center punch so it wouldn't move under recoil.
