I’m building a 12.5 upper and for different reasons a chrome-lined midlength Faxxon barrel cut down from 16” to 12.5” is what I’m going to run. Gas port measures 0.075”. Gun will be used 50/50 supressed/unsupressed running M855 or similar duty grade brass cased ammo only. Gasport large enough to run it unsupressed? If not what size would you recommend? I have an adjustable gas block I could use to run different settings for suppressed/unsupressed if necessary. Any thoughts?
