NcStar AK/SKS FRONT SIGHT ADJUSTMENT TOOL Review Part One

The intention of this video, is not to bad mouth a company. It is to make people aware that there is a potential problem with this product. There are some, who have had good luck with this tool and have said good things.
I am under the assumption, that this is likely, part of a bad batch of tools that was made, I know how quickly a machining process can go south if the products are not checked often enough.
I have made NcStar aware of the problem.

If you have had a good or bad encounter with this tool, Please mention the variant of AK you are working with, and what you think of it.
The adapter for the elevation adjustment works great.

The problem I had with this tool was the windage adjustment "hole" is too small (.3915") for all of the variants of AK (.3950") that I have, minus the Chinese.
I feel that I have done an adequate job of demonstrating that the hole is too small on those variants. If you have any other questions, please ask.
I would really like to know if this is just a fluke? or if it is a problem that has been swept under the rug?
