The only reason I mentioned the RLGS, is because the gas port pressure , “should” be at a lower level with the RLGS over the Mid-LGS.
I say “should” be, provided the gas port isn’t drilled over sized.
And the lower pressure level will make for a “gentler” cyclic speed.
This chart, while for a .223… shows the differences in a .223… but you get what I mean
