I have an 11.5" and just built another 10.3 upper with the crane spec .070" gas port. All suppressed.
I'm sorting through what is the best combination for the 10.3 barrel suppressed. I have used sprinco blue w/H2 buffer on some of my SBRs.
Although I do have an 11.5 that runs like a sewing machine with a Bootleg BCG. For my 10.3 fighting gun, I do not want to use an adjustable BCG or gas block. I'm thinking H3 with a blue sprinco?
What combination do you use for a 10.3" suppressed barrel to soften things up, eject brass at around 3 o'clock and still remain reliable?
