I went drastic on mine. H3 (5.4oz) and a heavy spring. and it still eats the nosler brass on a hot round.
the weights and springs needed are dependent on the distance of the gas port to the end of the barrel. the longer gas systems seem to be much easier on brass.
I have a white oak 24" barrel with the extended gas system that I use the H3 and heavy spring that requires no gas adjustment.
also have an 18" AR Stoner barrel with the same setup that could use some adjustment to the gas system on a hot round.
keep in mind that I am using handloads that create much more pressure than factory ammo.
I did some handloads for another member using an AR Stoner Barrel that cycle his gas system but when he tries factory 62gn ammo the gas system doesn't cycle in cold weather.
