All,
I'm putting together the pieces on a precision build around a .223 Wylde White Oak 20" DMR barrel. Will be using this primarily to predator/varmint hunt and improve my marksmanship (in addition to teaching myself how to shoot with milrads via a FFP mil/mil optic I'll pick up - likely the SWFA SS 3-15x). I may get into practical/tactical precision shooting with this setup if there are groups in my area.
From what I've read, for precision shooting a clamp-on gas block is basically mandantory, but there's also concerns of those clamps working loose. It's not as rough-and-tumble as a taper pinned gas block.
A. Go Adjustable?
Since I'm getting a clamp-on gas block regardless, is there a good or justifiable use case for an adjustable gas block here in addition? I don't have any plans on purchasing a suppressor for my rifles, and since it's a rifle-length gas system (and a 5.56 anyway), it's hardly going to be beating my shoulder up.
B. If Yes, What Model: JP or Syrac?
If an adjustable gas block has benefits outside of shooting with suppressors, what model makes the most sense?
On one hand, the JP adjustable model has four screws, which seems like it would provide a more secure clamp onto the barrel. But, there's no way to secure the adjusting screw. Since it's a clamp on anyway, there are potential issues all around for things working loose.

On the other hand, the Syrac has the detent system built in, but that also means you've got to use both hands to adjust the gas, which I'm fairly ambivalent about. I don't know how much of a factor that would be in the real world.
The detent and screw up front don't make much difference to me, as the gas block will be exposed with the 12" handguard I've got. Actually, I think I'd like the position on the side like the JP a little better anyway; easier to get to.

If an adjustable gas block isn't worth it, then I'll probably just go ahead and snag a VLTOR clamp on model and be done with it.
