May be a dumb question. I have a JP SCS H2 for a build. Mega upper and lower, head spaced bolt, adjustable gas block and a Barg CLE 224V 22” barrel.
Any suggestions on which of the 5 springs to start? Have a spare steel and tungsten weight to tune. Want to push a bit on velocity and not beat brass up.
