    Default Please help. Bam b21 won't cock

    Hi guys
    I have a bam b21 or b30 side lever rifle(its the one with fibre optic sights >. Problem is that when you pull back the locking lever it just hits a dead stop and won't cock
    Can anyone guide me to some detailed trigger diagrams or tell me who might be able to repair this. I'm in Capetown.
    Thanks in advance

    Thanks. That helped quite a bit. I think the problem is a koeksister shaped spring is causing the piston rod to not locate correctly. Anyone know where I can get bam springs and seals etc?

    35 coil springs, estimates:
    19.5mm diameter (outer)
    13.3mm inner
    Length about 280mm
    Price around R120, i keep instock.
    Piston seals 25mm but i cant remember price. Send me a mail in the morning.
    If im not mistaken, some gamo models came out from bam factory so most probably will work

    Hi guys

    I don't mean to hijack someone else's thread, but since I have the same problem with the same air rifle, ie. BAM B21... not cocking, I decided to write here instead of opening a new thread.

    My B21 suddenly did not cock. After opening it, I saw that the little piece which has the 2 trigger adjustment screws seemed to be leaning in the wrong direction. I realized that something was wrong with the spring which holds that little mechanism in the correct place. To worsen things, I made the mistake of pulling out the pin which held this spring in place and now have no idea as to how the spring should be.


    The spring I am talking about is a tortion spring which is held in place by the same metal pin which holds the metal piece with the two trigger adjustment screws.

    Is there anyone who could help by means of a diagram or sketch as to how this spring should be placed.
