Hello!
I’m thinking of building out an 11.5 with a Rosco patrol length gas system and was wondering what I should go with for a buffer weight. I’m thinking of using a Sprinco red spring, and am planning to suppress it later on down the line, but run unsuppressed for now, and I’ll ideally have an adjustable gas block on it. I mainly shoot 62gr PMC green tip if that helps. Thank you in advance!
