There used to be a chronic problem with the Air Arms Pro Sport where the bolt fastener of the cooking link would become loose and the owner would have to loctite it. Has this issue been officially addressed and fixed by AA, or does this still happen in new Pro Sports?

Another question about the FAC version of both Pro Sport and TX200 MK3 in .22 cal. On the official site AA states that the FAC Pro Sport .22 has "14-17" FPE muzzle energy while the TX200 MK3 has 15-18 FPE of muzzle energy. Is the TX actually more powerful than the Pro Sport in FAC configuration? I seem to remember that the Pro Sport has always been the more powerful one so I wanted to verify the accuracy of the information published on Air Arms' site.

Appreciate your help.
