I spoke to UA last week and the Superior liner barrel kits are coming out for the 480mm Dreamtac. When who knows. I raised my regulator pressure from 150 bar to 170 bar and shooting the hybrids at average 860 fps (I hear the hybrids like 900+ FPS-but they sure like 860) with a deviation of 4 fps. I did though have to change my moderator to .30 as they were clipping. Without a moderator, no issues, but as you know this gun barks. FYI, I measured the Decibel readings on the .25 and .30 moderator (Donny FL Ronin-Nice can) and negligible difference.
