Adjustable gas key
#2
The advantage to this approach is that you no longer are choking the gas port, which is a factor in early port erosion on your barrel. We want gas to freely flow through the gas port into the tube, rather than hit a choke device in an adjustable gas block.

Critical to its functionality is going to be prevention of leakage in the rear of the key where the set screw is, and the continued ability to turn the set screw, which commonly is carbon welded in place on gas block systems.

I'll look into these myself and try one out. You want to degrease the carrier and key thoroughly before installing, which I would use acetone on heavily until it is bone dry. You also want to compression stake the Grade 8 fasteners with an appropriate tool.
