CAI Galils with GLN Serial Numbers are good to go. CAI Galils with GAL Serial numbers generally have soft receivers. Best source for mags I have found is Palmetto State Armory. They will run like an AK if you keep good ammo in them and they are acceptably accurate. Maybe 2.5-3 MOA from a bench. I enjoyed mine and will be buying an actual IMI one if I can find it.
