    You made your piston system out of tool steel and titainium. I was planning on making one out of aluminum and stainless steel. If I made one like this since I would use softer aluminum I'd put a little shoulder on the spicket (?) to keep it from being battered into the gas block, and make the spicket a non removable press fit so I wouldn't wallow out the hole from taking it in and out. I figure it would be similar to the mini 14 gas block. Do you think that will work ok, or see any problems with it? and what type of SS should I use?

    Good! It might be easier for people with less machining experience (like me) to make a working piston system if there's fewer parts.

    I was thinking of a aluminum gas block with a stainless sleeve for the piston bore for my next varmit ak. the same idea would work here as well.

    What would be the best type of aluminum to use? Would 6061 t651 aluminum be ok?
