Anyone know what size a FAL gas piston should be?

[goon]

Does anyone know what diameter a FAL gas piston should be. I am trying to clear up a minor issue with mine and I think the gas piston may be a little undersized. Also, I have heard that the replacement pistons DSA sells are slightly oversized. Is that true? Does anyone know what size they are?
Thanks.

Try asking over here in the "Gunsmithing and Build it Yourself" section:

Already over there.

Big enough that the one I got wouldn't fit in my rifle. I kept the original. Just have to run the gas setting a notch higher.

I have two Imbels that measure .430 and almost .431. My DSA measures .432.
