Best "long term" adjustable gas block?

Do the POF and Noveske vent gas like most other adjustable gas blocks?

Are you asking if the adjustable gas blocks leak? Or are you asking if they use venting to reduce the amount of gas that goes to the BCG?

The SLR I'm using leaks, but it does not use venting to control gas flow. The SLR (and a far as I know the others as well) restrict gas flow

Yes, I guess leaks is the more accurate way to say it.

Am quite certain my SLR Sentry 7 clamp on does not leak, at least around its contact with barrel, as I removed it and journal was completely clean, no trace of carbon. Now front end of gas tube did have some carbon deposits first inch or so, common in my limited experience. This makes sense, as clamping action allows gas block internal surface to pretty much mate to surface area of most of barrel journal. I know some folks dislike clamp on style, but as long as excessive torque on screws is avoided, they are not likely to shear. High temp moderate strength loctite (246) and witness marks are my insurance of gas block not moving.

This thread makes me less willing to try an agb, even slr. Could one get a suppressed sbr to run without too harsh of a recoil impulse/gas to the face by simply using an A5 w/ the "right" buffer, green sprinco and an LMT e-carrier? Let's also assume a surefire socom II is used, and the barrel is a 10.5" centurion arms lw chf bbl.

I mean before today's gas blocks, carriers and charging handles, was it a complete miserable experience to shoot suppressed?

Answer: Yes.

I know I'm reviving this thread but I have SLR, Superlative Arms, and Syrac Gen 2,... had my first Syrac lockup last weekend - destroyed it trying to free it up, other Syracs were very difficult to break free, the SLRs were cake, and the Superlative Arms is newer but still very easy to turn...

I neglect them all equally so take that with a grain of salt but I will move away from Syracs to only SLR/Superlative

Unless something has changed, Syrac is out of business.
