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.

    The XS79 is more versatile than the 78 due to the fact that if you fit an on/off valve to an 88g cylinder you can refill it yourself from a bulk supply thereby keeping your costs down. Lubricant for the seals - Not really a lubricant as such as the seals aren't moving parts, but a smear of Silicone grease or oil will help keep them in good condition and supple for longer. There is no difference in the power output whichever source you use but what you do get is more consistant shots out of the 88g bottle simply because it's bigger. Less waste too. Given that you should get about 50 decent shots out of 24g before the power drops off, I reckon you should get 190 to 200 out of the 88g. It's the same amount of waste left in the reservoir at the end but you will only change the 88g once compared to 3.5 times with the 2x12g. Hence in total less waste. BTW get your CO2 88g from www.tyreinflators.co.uk and you'll save a packet.

    Oh I wish they did as standard! My experience of all the QB/XS family of guns is that they can be anything from under 6ft/lbs to 11ft/lbs out of the box. No two guns ever seem to be the same. However given a little TLC, a few minor mods and a reseal they can be made to give respectable velocity figures.

    As Biffo says they are extremely variable in both quality and power. They are also a doddle to fettle properly and there's lots of info on the web. The big drawback with the 88g is if you haven't bought an on/off valve then if you need to strip it you'll loose the rest of the co2. Not a cost issue on 24g or even 12g plus an empty but it gets expensive throwing away an 88g unit. Cheap enough at £50 but budget for that on/off valve.
