I have used adjustable gas blocks for several years now.
I have a rifle with JP LMOS components for 3-gun and an adjustable gas block is useful for reducing gas to further enhance the lessened reciprocating mass.
I used an old JP set screw design, and currently have two of the Syrac which have detents and are click adjustable. Syrac is no longer in business but I am very happy with the products. One is on a 3-gun rifle that is tuned to nearly eliminate sight disruption . The other is used in a rifle with a silencer that is overgassed due to the additional backpressure when fired with the silencer attached.
If you are using a standard AR-15 and standard components, they really aren't necessary. Take things outside of the design envelope, and they can be quite useful.
