Suppressors adjustable gas block

How necessary? Not very, unless...
Lots of ammo has been shot through suppressed fixed gas guns. Is a Switchblock or other adjustable system nice? Yes because it minimizes blast gas to your face and reduces the over-gassing effect that suppressors can cause.
Consider, though, that the original gas system was designed for specific parameters, among which a suppressor was not. When you shoot a suppressed gas gun, you will experience what I am referring to.
Try an adjustable gas block, for the cheap route. Noveske's unit is pretty trick. Or look at Robinson's system for their gun.
Is it necessary? No. For longest life of your gun? Yes. But so is tuning each gun individually due to friction, ammo, type and amount of lube you use, how dirty you let your gun get, etc.

I shot my 5.56 AR's suppressed for quite some time and thought all was well. Then put a Seekins adj gas block on one and it was like night and day.
Benefits were
Gas in face issue.
Brass goes in a little pile.
Much reduced recoil impulse.
Faster follow up shots on coyotes due to less bounce with scope at high power.
Cleaner rifle.
Accuracy is better due to smooth consistent recoil impulse.

my ACR has an adjustable gas block switch, which is very nice with my m4-2000. I can tell quite a bit of difference in gas blowback and recoil when using the block in S mode vs U mode.
Here is a good post started by George Gardner at GA Precision on suppressing an AR:
