Works well

I think a different coating would raise the quality nickel or chrome. Only has four adjustments. I run this on my 10 300 aac with socom762 rc2 and my 18 223 Wylde mk12 clone with AEM5. Really a properly sized gas port is all you need but when running a suppressor this helps take the edge off a little. I find when its shot a lot (300ish rounds) with the suppressors adjustments are difficult to make on the fly. So like a standard adjustable gas block set it and leave it. It is pretty easy to clean no screws to strip.
