Two new DSA pistons = .4305
stg58 slightly used = .431
Used Imbel = .4295
Used R1 = .4285
Entreprise = .4270~.4275
Century 2 piece (pos) = .427

Gunthings verifies their pistons at .430

Only tube I can measure right now is an Imbel which runs .433 id at gas block (or threaded end).

Hope this helps a bit.
