SVT40 gas adjustment?

[Soxfan9]

What are you guys using to adjust the gas systems on your SVT40's? I have seen a repro tool available online, but the ad for it says that the gas adjustment portion of the tool wont work on most rifles (too sloppy).

I bought one off a guy on Gunboards that works great. He makes them and has a gunsmith shop. Price was cheap too. Search through Gunboards forums for the link.
