    The majority of users do not want to read about these subjects and people have left the forum as a result of it – this is after all an 'Airgun' Forum. It’s all very well to say they don’t have to read it if they don't want to, but as most of us use the ‘New Posts’ button there is no easy way to avoid it.

    All AGF staff members are in favour of people being able to discuss what they want, but we have to draw the line somewhere if it is upsetting other users. We don’t want to read about these topics either, but are forced to do so to ensure forum rules are followed.

    IMPORTANT- In future, please put all your posts about any offending topic into the http://www.airgunforum.co.uk/community/index.php?forums/adults-only.46/. To do this, you will need to contact admin or a moderator to ask for permission. By doing this, people will not have to read it unless they opt to join in too.

    Staff will not move posts for you if you put it in the wrong section – it will simply be deleted. You will then have to type it all out again and put it in the right place, so heed this warning.

    Although all normal forum rules will still apply; moderation will be a little more relaxed in this area. We will however, not tolerate bullying or personal attacks, racism or any other offensive 'isms'. Its purpose is to remove these topics from the main forum, not give you an area where you can abuse each other. We will not hesitate to ban offenders.

    They are O rings, just visit your local engineering supplies with the old rings and they will sort you out.

    Good grief
    This is proving very tricky to get the o rings
    Tried sever shops online in UK and Poland without any success (some Polish retailers prove difficult in selecting UK as a delivery option)
    If I do not get any further I think I will send the gun back to Poland as it is only a few days old - still awaiting email I sent them as they wanted pics of the missing O ring, but as they do not sell them not sure what else they can do

    Wonder if 8mm x 1mm would do the trick
    They are for the barrel seals on the end, 2 of them in fact

    Check out the Cromwell Tools*website for shops near to you. It must be easier to take a trip to one than risk sending your rifle to Poland.

    * Cromwell are main dealers of o rings but finding the actual ring on their websire may prove trickier than you would expect:rolleyes:

    ps Just looked at CP1 and I see SMK and Pellpax mentioned, have you tried both of them for spares?
    Have you accurately measured the o rings because if you have the size right Cromwell will do them by mail order.
    When you have measured them could you let me know the o/d , i/d and ring thickness and I will check my o rings and if I have any that match will send you some.

    They are very small to measure accurately, but think I have found someone that sells them, presuming the .22 and .177 sets are the same sizes

    As far as I can gather the ring size is 8mm x .8mm

    Ordered some generic ones off ebay hoping one of them will fit, but doubt it

    Is the 8mm the i/d or the o/d?

    on metric o rings the first number is the id and the second the cross section

    O rings are usually specified by the inside diameter and the thickness of the ring.

    8mm x 1mm is widely used on the AA S400 series - one goes on the shaft of the bolt, adjacent to the bolt handle, and another is the transfer port seal. You can get O rings by mail order from lots of places.

    Not sure

    The remaining one that is currently on looks too fragile to take off without breaking it

    Dug my calipers out and the nearest measure I can get is 9.36mm OD when it is on the barrel, so I would imagine the 8mm is the OD

    Also not sure if the rings are different on the .177 and .22

    So the 8mm could be the ID

    My head is spinning over this

    Finally bit the bullet (excuse the pun) and removed the remaining o ring with a toothpick

    It sure does look like it is 8mm ID with a CS of .8mm

    Ordered a couple in CS 1mm and hope they work, as it's the nearest I can find

    In a catalogue and if being measured by someone experienced with using or buying them,yes. If being measured by anyone not sure of what they want then it's best to ask the question.
