Just for clarification, when testing the various GCS do you check all 4 configurations i.e. Suppressor on and off, gas settting suppressed and Un-suppressed? Going to the range tomorrow and want to make sure.

I checked it with the Suppressor off, Gas Reg on Normal and with the Suppressor On, Gas Reg on Suppressed - loaded single rounds to ensure it lock back on an empty magazine, because you will get it to work / load following rounds but fail to lock back eventually.

It should still work suppressed on Normal Gas setting (it'll be overgassed) and I don't care if it doesn't work without the suppressor but on Suppressed gas setting.

Also do it for the weakest ammo you typically fire, but check with all you intend to fire.

Copy that thanks!

Follow up- I settled on the 1.3mm. No function issues with this size.
