I have been reading about Adjustable Gas Blocks and it seems there are two styles......
Flow Restricting - which seems to be the most popular
Flow Bleeding - Superlative Arms
Then there are the:
Clamp On Style
Set Screw Style
From what I have read the Clamp On and Set Screw seem to be about equal depending on who you talk with.
My question is: Is the bleed off a better way to go so that you can fine tune recoil and operation of the BCG??
They both do the same job. Their is no reason to spend a paycheck on an adjustable gas block. As long as you can adjust your gas flow you have accomplished what you are needing the gas block to do, regardless of price. I wouldn't spend more than $50.00 There are to many good adjustable blocks out there for that price.
