Bill A. found that .094" gas ports are most optimal for 20" and 24" barrels, while 16" MLGS barrels have a .078" gas port. I'm not sure what the MLGS 18" have, but you will want more than that with a RLGS 18", so .082" sounds like a good starting point. With factory 123gr, you should be running well. Who knows what it will do with 100gr and under with moderate/lighter loads. I guess we shall see.
I'm interested to see if 123gr loads that produce certain velocities in 20" barrels will be within 50fps out of yours, since you have a RLGS.
