MLGS is fine, with the right port diameter for 18" Trying to get an 18" MLGS with a .094" tamed can be a pain in the neck.
I've been dealing with an Underground Tactical 18" MLGS with .094" port that even with adjustable gas, is on the ragged edge between bolt locks back, and failure to extract due to excessive carrier speed. It really needs at least an H3 buffer, if not something heavier.
If your main purpose it to shoot out to 1000yds, I would look at a longer barrel. At my altitude, it doesn't really matter as much, but down closer to sea level, you might want more speed. I'm not sure where you're at.
