I've been searching for a while now and is there a list of gas tube and piston combinations that work with one another? I am in the process of taking a Maadi AKM and SBRing it with a M92 barrel. Turning down the barrel to fit the rear sight block, gas block and sight are not a problem.
But anyways, initial plan was to take a krink gas piston and use that. But it's way too short to work on a M92 barrel and keep the aesthetics. I can always make the gas tube shorter but I want to have wood on the upper handguard. So then I bought a M92 piston only to find out that it's too big to fit into the gas tube because of the stars. I even went so far as to enlarge the gas tube by heating it up and pressing a 10mm socket through.
A listing of pistons and their measurements would be great. I found a site that had barrel profiles which helped me out tremendously with getting the M92 barrel profiled to work with the Maadi parts.
Build is finally done, gonna try to media blast and paint it this month.
