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.

    Just a quicky, maybe!
    Would either of these be any good in an air rifle?

    It looks like it would be extremely hard to machine/fabricate out of one piece of material, as for sound suppression I have no idea.

    It looks like it would have to be made as an insert to go into a silencer 'casing',I'm not sure what it would be like to be honest,it looks like it's for real firearms?

    The top picture looks simular to an old Parker hale I have using washers.

    The first part of your answer is the challenge I like.
    It's the sound suppression part I really want the answer too. :)

    They are designed for firearms. But I'd like to know if they would work for an airgun as well. I can't find anything specifically for air rifles.
    Ps. They are the internals. There would be a sleeve over these.

    With air power vs powder burners, the air powered variants can use a wadding around the outside of the strippers. A bonus in my book. One of the most successful mods is the HW mod, which uses washers, hair rollers and felt.

    Perhaps shrink the entire diameter of the designs and introduce two or three extruding rings between the baffles? Then you could add wadding (brillo/scotchbrite/felt) between them, and still fit the whole lot in a sleeve leaving it centred?

    The internals look good for the expansion/dissipation of air, but I'm unsure how it would work in practice.

    No worries. I should have made that clearer.
    The pictures don't help, that's for sure. :)

    I keep reading this. What are extruding rings? Do you have an example of these. Are they cones with holes, for stripping/extruding the air behind the pellet?

    Honestly, the HW mod uses 2 washers, 3 hair rollers and some felt. Big chamber, wee chamber, big chamber. Kicks the arse out of a lot of fancy ones too. I've since put hair rollers to a variety of very good applications. :D

    The top CAD cap looks best suited to it, as you could extend the machining on the first, third and sixth baffles (and the muzzle and barrel ends) to provide the seal for the sleeve.

    Any idea what the white fabric is btw?

    Tend to find the scouring pads break up and foul internals after a while. Always wondered.

    My A&M is straight out heavyweight felt, but takes up like 5mm. Love to get me hands on some of that white wadding.

    My 55s isn't threaded but tbh I recon they are too long to have a silencer on as standard,the newer models are threaded and come with the silencer I described above,it's a good unit,a little on the large side though.

    My 60 is threaded. I was thinking of making a short mod that directs some air back down a shrouded barrel.
    I don't like a mod just stuck on the end of a barrel. My old rifle was a Fenman, almost all silencer. :)
