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.

    Hello all, will be doing a hpa mod to my ratty soon and have a quick question about the pressure it's running at/can handle. I'm aware that it's designed to run at 800-850 psi but surely it's been tested and rated to much more than that? Anyone know what it's max safe working pressure would be? Basically I'm looking at the option of running 900 - 1000 psi, im well aware that this will boost the power so will get it tested as I mod to make sure I don't go over 12ftlb. Also has anyone ever had/modded a ratty to fac level? I only ask as I have held an fac for the last 8 years so would maybe consider applying for the variant and modding the ratty to fill the slot
    Thanks in advance
    George

    Have looked at the hipac but not so keen on the lack of a regulator. Just going to use a regulated air bottle

    Ratty's can easily make 12ft/lb with 800-850psi (your normal regged air pressure presuming you're using a paintball bottle). So personally, I wouldn't risk using any pressure above this, you'll also get less shots per fill.

    in the states they run them at pressures up to 1600psi (regged paint ball tank) my king ratties are running 1350psi currently
    as to power depending on caliber power levels above 50fpe can be obtained if you use the aftermarket pcp tubes that are rated for 3000psi fills
    don cotheran has developed a valve to fit his pcp tubes that gives over 220fpe with a .357 cast bullet
    a std discovery tube and a 2260 tube(provided that the area of tube with the roll stamp isn't pressurised) will take 3000psi if uprated valve retaining screws are used according to one of the respected airgun tuners in the states(i personally wouldn't go over 2200psi)
    when he pressure tested both 2260 tubes and discovery tubes to destruction the threads on the filler caps failed at about 9000psi
    if you're looking to go fac with a 22xx or discovery look on a few of the american forums
