Ive had a barrel issue for years and have replaced barrels on virtually every pcp Ive owned and some get a few, I found the AA CZ my go to back in the day as well as the MPR/hft500 LW barrel but Ive had luck with oddballs like the Crossman and Cometa barrels on my old mk1 rapids, its why I was interested in the Cometa boingers, that said I found an old rfd that had bought hundreds of bsa barrel blanks from the 90’s, these were for a project but dozens were left, these barrels were exceptionally good and I passed them to lots of my friends too, most still have them fitted to something and one in particular keeps appearing on the sub12 guys utube site
