I know this question is probably only going to apply to a select few, but I'm curious to see if anyone else has gone through what I'm going through now and what the outcome turned out to be.
I have a .308 AR I just built. I'm using a Rainier Arms Ultra match barrel, SLR adjustable gas block, CAR-10 XH buffer and .308 carbine buffer spring from heavybuffer.com. I'm also running a Silencerco Saker. So I initially tuned the gas block without the suppressor in the typical sequence (basically start closed, open it as it reaches the different benchmarks and makes it to a complete cycle, and then up 1 more setting for reliability). My train of thought with this is that I'd always want the rifle functional regardless of the condition and not tuned to only run suppressed. So after the initial tuning, I threw the suppressor on. It increased my gas pressure so much that it is ejecting the spent casing so hard that it catches it on the way back forward. I verified this with slow motion video. When it doesn't catch, it throws the brass at about 1:00. So my gas it obviously way high for shooting suppressed. I turned it down a notch but haven't had the opportunity to retest under both suppress and non-suppressed conditions. FYI, I'm testing with Prvi Partisan 147gr. Eventually it'll be shooting handloads, probably in the 175gr range.
My question is, do any of you have a 308 build that you are able to run both suppressed and unsuppressed without swapping buffers or making gas setting changes?
