Several years ago I sold a left hand stocked, left hand bolt Daystate Huntsman for several reasons. It was mechanically, noisy to me. It made a burpy sound and the shot string took a lot of adjusting to get an acceptable bell curve. Adjusting the hammer spring tensionnot a user friendly process. It had a one piece tube instead of the easier to service two piece action that the Regal comes with. In short, it was more of a looker than a great shooter. The Airstream factory LDC was the least effective, hardest to remove factory moderator I've ever owned. I had to destroy the shroud end cap to remove it because it was epoxied in place and overlaps the shroud. It looked nice, but it doesn't noticeably reduce the sound level of a FAC powered Huntsman.
Early this year a forum member advertised a near new Daystate Revere true lefty sidelever PCP with O db moderator, extra magazine, and a 4-16X MTC scope at a price I couldn't pass up. I had recently sold a Daystate Wolverine 2 HP which had disappointing accuracy for it's cost. Every shortcoming I posted above about the older Hunstman (pre Regal) was totally improved with the new Revere. It is laser accurate, not pellet fussy, has excellent power and low extreme spread due to the factory regulator, is easy to cycle, has a much improved magazine, and is a keeper for sure. It is powerful and consistent with no adjustment necessary. It is quiet at the shooters ear, and the O db moderator makes it whisper quiet downrange. It is one of my favorite PCPs ever. The ugly duckling is now the swan.
