So do some research on these things....
My understanding from the "pros" seems to be that an adjustable BCG is like a last ditch effort...
A well tuned AR would be tuned going top to bottom. Even the adjustable gas blocks are in reality a band aid for those unable to properly tune via port size and/or buffer spring/weight.
1) Ideal port size
2) Ideal buffer spring/weight
3) Adjustable gas block
4) Adjustable BCG
