I'm using an Armaspec Stealth Captured Spring (H2 weight) with my 18" MLGS barrel and my action cycles well and I don't even notice the recoil. You can buy a kit of tungsten weights and experiment without buying a new buffer. There are however some barrels out there with gas ports which are larger than Alexander's spec and they may still need an adjustable gas block or gas key to tame them.
