1. The Forum Rules have undergone some minor changes and updates.  Please take the time to read them; it will only take a couple of minutes of your time. By doing so, you lessen the chance of incurring the wrath of the moderation team or making yourself look foolish to other members.

    90% of users posting adverts in the Sales forums need to be reminded to read the rules as their posts are wrong.  This is unnecessarily time-consuming and will no longer happen - if your advert doesn't follow the Sales Rules it will be deleted and you'll have to start all over again.

  3. Dear members,

    Our membership (like our country) consists of people from all walks of life; different in far more ways than can be listed here and each with a different view based on their experience of life - regardless of their colour, religion or cultural heritage. Every single person in the UK has been born of mixed race – we are a multi-coloured and multi-cultural country.

    As many of you are aware there are a handful of individuals amongst this membership that persist in making provocative, inflammatory, racist and otherwise offensive comments. This has been happening across the forum to a certain degree but is most especially prevalent in the Adult section.

    The moderation team has tried to stay on top of this, however unfortunately because of the ‘offensive’ nature of much of its content we don’t monitor the Adult section quite as much as perhaps we should. As a result much of this behaviour has gone unnoticed unless it has been reported to us. While the team always intended to take a "light touch" approach to the Adult section it would seem that some people aren’t quite adult enough to be left unmonitored after all.

    This behaviour is, and always has been against Forum Rules as well as the specific stipulations of the Adults forum and it will no longer be tolerated. We feel it's time to draw a line in the sand and as such from this point onward offenders will receive an immediate and permanent ban from the forum.

    In order for us to achieve our goal of restoring the forum to the friendly and tolerant place it once was, we ask that ALL members be mindful of the content they post and help us to stop unacceptable behaviour by using the 'Report' tool at the bottom of any offending post - the results of which can be seen only by Admin/Moderators.

    You should all receive a copy of this message by PM.

  5. Postings on Politics, Religion & Controversial Off-Topic Material

    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.

    IMPORTANT- The discussion of politics and religion is no longer allowed anywhere on the forum (including the Adult section).  The only exception is if it's airgun related - they must be put in the Airgun Related Politics section..

    We will not tolerate bullying or personal attacks, racism or any other offensive 'isms'. we will remove these topics from the forum, we will not give you an area where you can abuse each other. We will not hesitate to ban offenders.

    I was hoping you all could help with an issue that has developed on my Cometa 300s springer. I mounted a new scope on it with standard, one bolt, high rings and after about 50 shots the scope had shifted all the way off the end of the dovetail mount. The rifle has no scope stop plate or holes for a vertical scope stop. Any ideas on how I would solve this issue? ATB

    Get an arrestor block, that'll stop it.

    Would it be necessary to use a single piece mount and an arrestor block or would the single piece mount be ok on its own?

    Do the arrestor blocks work without a hole for a vertical stop screw??

    Yes. I think it's down to their weight.

    would a single piece mount do the trick on its own?

    Your 'One bolt' scope mounts sound a bit feeble, they probably aren't really up to the recoil of a springer, getting a one piece mount could be the answer, as could an arrestor block: http://ant-supplies.co.uk/Pages/DovetailRailArrestorBlocks.aspx.

    You could try Loctite or even superglue on the grooves, it won't damage the finish but will need some cleaning to get it off afterwards.
    Also if you are happy to do a little metal work you could drill & tap the cylinder for an arrestor stud, I would pick M6 thread as it uses an ordinary 5mm drill bit, you will have to take the spring & piston out though.

    With that sort of movement I would be worried about damaging the scope. If you arrest the movement with a block the shock will travel through the scope. I am quite new to shooting but summise that scopes for springers must be available which will take the shock load.

    True - I would hesitate to put an expensive scope on a springer they have a reputation for wrecking scopes, the weird backwards & forwards recoil is worse than a normal centrefire firearm

    I've got a Hawke Airmax which are supposed to be extra sturdy & rated for airguns, & a Dampamount on a gas rammed Lightning - after 5 or 6 years, so far, so good.
