The quality of AGB has come a long way. Klem has a good routine and it will help keep the port clear. I have run 800+ rounds down one pipe with an AGB, and started to have short stroking. 8 clicks closed, 8 clicks back open and life is good. You could forget about that with the original AGBs from 6-7 years ago. They were locked up solid with carbon at that point and were done.
If you have the right wrench for adjustment, then it is not a PITA.
Better to have it and not need it.
Cons - if you are wanting the smallest OD handguard possible, 100% free floated barrel with no recoil contact, then you are going to have some issues unless your handguard stops short of the GB.
