Adjustable gas block tuning, changing buffers?
I am going to experiment with an adjustable gas block on a pencil barrel build. My goal is the softest recoil and least muzzle movement while remaining reliable with the one load it is tuned for.
A common recommendation is to close down the block until the bolt just locks back on an empty magazine then open it some amount e.g. half a turn. That doesn't seem precise. Would a better way be to tune it to just lock back with an H or H2, then leave it there and run a standard carbine buffer?
