Watching the video, you get the impression that the ProSport gives off a 'sproing' noise. I've never noticed that about my fairly recent TX200, so I'm gonna guess that's an illusion provided by the sound equipment. Even if the noise is bona fide...who cares? The rifle shoots like a laser!!! This is a fine, fine air gun, but would not replace my TX in my stable...however, it would be a worth addition to it! When I bought my TX, I considered the PS, but really, they are two different rifles that share the same powerplant...and for my uses, I believe that the longer rifle works better...but I wouldn't kick the ProSport off my wall for eatin' crackers!!! Good video, love seeing springers being featured, since PCP's just leave me...cold.
