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.

    'Behaviour

    Do not make inappropriate or offensive posts - including threats, harassment, swearing, prejudice, defamation, deliberate insults or name-calling, other negative remarks about this forum, its moderators and administrators or your fellow members. Even if this is just your own personal opinion, RESPECT YOUR FELLOW MEMBERS.'

  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.

    The “Tune” consists of the following: The rifle is stripped from top to bottom; all the parts are inspected for wear and tear, poor efficiency and general quality. Orings are replaced as standard; other parts may be chargeable although I do replace many damaged parts for free as standard.Hammer mechanism• Ensure the assembly is free of any oil, grease or debris which can cause consistency issues• Hone hammer spring to a higher accuracy • Polish the bearing surfaces in the hammer • Fit PTFE slip disk• Custom made hammer weight & guide to minimise hammer noise & increase efficiency
    Loading assembly• Bolt modified for better airflow, pellet feed and to increase accuracy• Bearing surfaces polished• Probe guide and pellet tray are modified for smoother loading and to reduce pellet fussiness • Cocking is modified on early models to remove the need to pull the bolt back further when loading a magazine if requested• If you include the magazine in with your rifle they are also modified to increase accuracy• The magazine locating pin is modified to give a more responsive load• Lubricant is added to parts of the assembly to allow a smoother action
    Exhaust valve, transfer port & barrel• The exhaust valve stem assembly is modified to run more efficiently • Valve is refaced to a higher accuracy• The valve pressure is reset to give a better performance between heavy and lighter pellets• The transfer port is modified to give a higher degree of efficiency • Breech face modified to reduce wear on the pellet when loading• Crown of the barrel re-cut the to increase the rifles accuracy
    Trigger assembly• Sears are polished to a smoother finish• Hammer latch pin polished & refaced • Trigger pin assembly is reinforced to reduce movement from left to right• Trigger let-off is set to a comfortable and safe amount. • 1st stage travel can be reduced beyond standard adjustment at request • Safety mechanism modified to give an easier movement & reduce noise

    the cost was a little under £400 for all the work and shroud (excluding the new stock ), shot counts well over a 100, would say 110, have had it at the range and it shoots great, very quit and deadly accurate. mite sell it if i dont get enough time to use it so watch the for sale threads,
