Which adjustable did you go with?
The Superlative Arms bleed off one. It's my first adjustable gas block, all I know is that it fixed my BCM 11.5" SBR's malfunctioning with my SIG SRD 556 Ti can.
After running it hard and without issues, using M855, Tula, and reloads:

I know this is an old post, however, I just want to share my experience. I have a BCM low profile gas block and I used Loctite red (#271) on the set screws and DID NOT pin the gas block to the barrel. That was 2 years ago and now I wanted to change the handguard, so I had to remove the gas block. The loctite label says to heat the threads to 500 degrees to remove. I used a Wagner heat gun on high for about 6 minutes until my gas block started to turn a gray/white color. The sets screws easily came right off. Originally, I tightened them to 25/inch lbs, and never had any gas leaks or cycling issues. I hope this helps somebody one day.
