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.

    To close this box once you've read it (and the Rules), click on the X in the top right-hand corner.

    Thank you.

  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.

    Can anyone please tell me where I could buy one, I tried blackpool air rifles they are out of stock.
    I would like to try one in my mk3 tx to see what difference It makes to the way it shoots before considering changing the piston rod or paying for it to be tuned.

    There's a few here David.

    The AA seal configuration & dovetail is a pretty poor affair in my opinion.

    My piston noses have a HW fitment so the standard AA seal can be replaced. They can be converted to slip over the existing AA dovetail but you probably won't get the amount of short stroke you want on a MK3 alone MK1 & MK2 will be ok.

    How they work:- On a TX they are designed to be used in combination with my piston latch rods. (which are CNC machined & made from the correct material & heat treated to the correct hardness, not tool steel or case hardened mild steel)

    A groove is machined into the part for a custom made bearing to be fitted so it actually does something.

    On an HW the existing seal fitment is machined away on the piston exposing the latch rod. The rod is then threaded, the custom nose is then machined the required length if a longer stroke is required prior to being screwed & loctited onto the latch rod.

    So as you can see although they can be fitted at home they are not intended to be just a short stroke "add on" they are an upgrade designed to take some of the best custom seals available. I myself use Vac25 from Vortek in the USA in a TX or 25mm HW & the new 2013 26mm seal from HW.

    Other things to consider is the spring, transfer port, spring guide, top hat & piston lightening. Hope this helps ;)
