First, my air gun experience is at best limited having only own 4 in my life. After buying the last gun, Umarex Gauntlet, I began looking at air guns from a different viewpoint. The world of PCP guns is very interesting and want to ask a few questions, I have reviewed the posts, but have not found an answer to my questions.Question 1: I will be referencing my questions using the Gauntlet as my basis. I have noticed the barrel tuners and it is interesting, to me, as to why the tuners are mounted on the barrel shroud? The barrel shroud of my gun is very weak, is this the case in most guns? After removing the shroud I noticed that the barrel is anchored in two places, the Breech and the air stripper. It appears to me that the barrel can and will move in several planes when the gun is fired. How does the shroud-mounted tuner help with the harmonics since it allows the barrel to dance in all directions?This is WHY those who really are chasing the best accuracy from PCP's Do Not shoot PCP rifles of this build design. Unless barrel and receiver are VERY SOLIDLY attached to one another will there be no movement between them. Add a barrel band further out towards muzzle and any shift in air tube with pressure moves the barrel with it ... BAD for accuracy. Most high accuracy guns run with floated barrels only being anchored to receiver and optics mounting. Question 2: Since we are trying to control the harmonics of the barrel, would it make sense to control the barrel movement via "O" rings mounted to the O.D. of the barrel with a diameter that would allow the shroud to slide over the barrel/"O" ring combo yet provide some damping? Another approach would be to mount metal rings around the barrel again with just enough clearance between the I.D. of the shroud and the O.D. of the metal rings to allow the shroud to be replaced onto the barrel? In either case, the "O" rings or metal rings could be moved along the length of the barrel to aid in the harmonic damping.Thinner a barrel is ... worse will be its harmonic whip tendency. Stiffening shrouds ( disguised many times as silencing devises ) simply add weight and length making barrel flip and wiggle worse !! In these designs anchoring the shroud in rubber etc within a barrel band works to some degree, but still remains a crutch in addressing barrel wiggle from a shotty attachment at receiver connection. Please, comment with an eye to allow me to better understand this sitution.Don't take that as a low blow on what rifle you own or others who read this who also own such rifles of similar design. These are simply matter of fact design shortcuts to make an inexpensive to manufacture and sell airguns.Knowledge is power and more you know better is your ability to wade threw sales hype and better grasp straight up mechanical comprehension of cause & effect in designs manufacturers use.ThanksLarry
Motorhead, I take no offense to the answers you have supplied. This is just a part of the learning experience for me. I am very eager to learn more. I am aware of some of the higher-end air gun designs with the open barrel ( no shroud), but you must stand before you walk. Look forward to learning more and asking more questions, again thank you for your response.Larry
