The micro is just a custom drilled gas port on a standard block. I'm probably going to go with a .053 instead of the .043 with most suppressed blocks. Should be enough to run unsuppressed but not let too much gas come back intoy face.
With the full size can the back pressure was low enough for me to use the standard noveske low profile without any over gassing problems using only an h2 to slow things down a little, but the specwar K is going to force me to swap over to a micro govnah and just leave it at the suppressed setting.
That's a 11.5" noveske barrel and 11" noveske nsr rail. It took a gem tech 1/2 turn spacer to get the clearance but now the can sits perfectly against the rail. Now I just have to wait for my specwar k to clear and it will be my dream rifle.
