    Question Air Arms Pro Sport loose bolt issue

    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.

    The FAC difference is only the barrel length the HC is the same, the bolt you mention is not the best way to connect linkage to the cylinder but AA did improve the bolt a bit on the later models.

    yes longer barrel will help in FAC.
    ALso you can squeeze a little more stroke out of the TX with a few mods, and a few more mil if you have a lathe.

    It will also be a hell of a lot easier to cock !
    Always looking for any cheap, interesting, knackered "project" guns. Thanks, JB.

    My early Prosport's bolt never came loose but I have thread locked it when I tuned it, my other Prosport I had many years ago never came loose either.

    Just thought I would post a picture of the small difference with the later ones I have also added a picture so you can see what I mean by a shorter barrel the same as the HC.

    I was wondering if you knew about the weak cocking lever on the early PS, AA did update the lever on the later models

    You are my new hero! Thank you very much for the fantastic information that certainly puts my mind at ease buying one.

    You should head AA's technical department since you know more that they do, judging by the useless email they sent me

    I believe they are discussing the hex head screw which attaches the cocking link to the compression chamber.
    If it comes loose the underlever won't return to the correct position after cocking.

    I have 2 Pro sports.

    One has been my main hunting rifle for over 15 years with zero issues on the cocking arm.

    I sold my prosport. Could not get on with the uncomfortable cocking lever and my boney fingers. Tx is much better to cock. Id not have another prosport.
