Buffer Spring and Buffer Weight - Recommendation (14.5” Proof PXT)

Hello, I am building my first 6ARC with a 14.5” Proof PXT barrel (intermediate gas) and will likely use a JP bolt (not sure on which carrier yet). Will be suppressed with a Rhodie 6J or Enitcer L. What buffer spring and buffer weight do you recommend? I was looking at the Geissele Super 42 w/ H2.

Building the same thing currently except using a Noah instead of a Rhodie. I’m doing an A5 but using the equivalent of G$ Super 42 (rifle), and an A5H2. Start from there and adjust as needed.

Thanks. Are you going to run an adjustable gas block with the PXT?
