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.

    About to leak test a pcp. I don`t have a diver bottle but do have access to high pressure nitrogen , normally use a pump but in this case not ideal for multiple charges in a short period. My question is has anyone used nitrogen in a pcp and before I start is there any glaring reason I should not , thanks:confused:

    Its possibly illegal, have a search, its been done a few times on here.

    Any reference to an air rifle, air pistol or air gun—

    (a)in the Firearms Acts 1968 to 1997; or

    (b)in the M1Firearms (Dangerous Air Weapons) Rules 1969 or the M2Firearms (Dangerous Air Weapons) (Scotland) Rules 1969,

    shall include a reference to a rifle, pistol or gun powered by compressed carbon dioxide
    .

    So, an air rifle, is by legal definition, run on air, the amendment to S.48 of the firearms act was included to allow carbon dioxide.

    And....

    By virtue of section 48 of the 1997 Act, firearms using compressed carbon dioxide as the power source are treated as air weapons and, if not regarded as ‘specially dangerous’ (over 6 foot lbs in the case of a pistol or 12 foot lbs in the case of other air guns and air rifles) are thus exempt from the firearm certificate procedure. Firearms using other gases are not so exempt

    We have had this topic raised several times, and the opinion is that nitrogen is ok, as breathable air contains mainly nitrogen, so your seals should be fine. Legally it may not be ok as you are using something other than air or co2, which may not be permitted with air guns.

    Thanks guy`s , had not considered legal implications was only thinking of potential damage to gun. A classic example of what makes this site so valuable. Never intended to use nitrogen as a propellant purely to test for leaks just goes to show how dangerous ignorance can be even with the best of intentions.

    I'd say stick to what it was intended for, Breathing air only.

    If you find yourself needing repeated fills and a pump is not suitable, why not invest in a tank?

    If gas rams are nitrogen filled, why does not that make them illegal then?

    I would guess gas rams are ok because the nitrogen is not the propellant. A gun with a gas ram still uses air produced by the ram and is therefore still an air rifle.

    The ram is also a sealed unit. Although rifles like the Theobens or HW90, use regular air and require a special pump to increase/decrease power.

    my guess would be as the gas ram pushes the air which then propels the pellet its still classed as "air powered" the ram is just the replacement for the spring.
