Plan on buying two uppers and doing a P/W job using FCS 6315KM devices. What spring/buffer weight combo should I run for suppressed and unsuppressed use?
Mine came with H2 buffers. Runs great with Dead Air Sandman S and K. Gas block position 3 for S and position 2 for K or unsuppressed. Position 1 for adverse condition or weakest steel-cased ammo.

This.
I'm running both of my PWS uppers with the standard PWS H2 buffers and their tubes. I believe both might have blue sprinco springs though.
