Rather than starting a new thread, I thought I would just add to this since it relates to the same rifle. I got my gas dialed in and my SA gas block is superb for handling both suppressed and unsuppressed fire( which rarely happens,lol)
Currently it's a 20" monster but I have an itch to assemble an upper with a longer barrel to get all I can out of this, with a gas gun at least. I'm leaning toward 24" but 22" isn't out of the question. My goal is 2800fps at approx 1-2000 DA in order to maximize BC. I imagine there are diminishing returns at or above 24 but 'think' it should just about do it. Any input from the more knowledgeable ones?
The other thing is gas system length....would going plus 2 or even 3 be beneficial as far as dwell time since it's pretty much always suppressed? An extra 2 to 4 inches of barrel is quite a lot and I can't fully wrap my head around that specific aspect of dwell time and bolt unlocking optimally or early, etc.
I'm going to a Precision rifle class this fall and these guys mean business, I don't want to fall short when things get out past 1k.
