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.

    my airpistols muzzle crack is louder than the pellet hitting the target. in the interest of others i want to make it quieter. so maybe a silencer is in order.

    i cant find one, if they do please direct me.

    failing that im going to make one. so i have a few questions and need some advice about silencers and making airguns quieter.

    firstly about fine tuning the gun for quiter operation.

    1.does valve shape and port champhering/reshaping effect noise levels? i know this wouldnt apply to most quality airguns, but a lot of the internals of this p17 arnt the best quality. would maticulously removing burrs and other minor defections of the internals help?

    2. does barrel exit shape effect noise, the barrel end seems pretty flat. would putting a little bevel or cup shape effect noise? more simply would using a countersink bit or putting a step in the inside of the end of the barrel, or chaning its shape in any way effect noise?

    3. any other ways to make a single stroke pnuematic pistol quieter beyond my two possibly silly ideas?

    secondly about a silencer (because the first section might of been dribble)

    1. i know real silencers are engineered with baffels etc, but will a peice of metal tubing the right shape filled with some foam plugged into the front make a difference? this is the easy lazy idea i know.

    2. due to the cocking mechanism a silencer will have to be removed each time the pistol is fired. the fake compensator part of the pistols front is where im going to be push fitting it for ease. will a couple of orings, the right sized pipe for and super snug fit suffice? or will i need a better locking mechanism?

    3. what baffle material should i use and what shape? particularly density and shape/design, possibity of varying density layers in ring cross section shape

    4. bottle shape or straight? will a wider cross section silencer with more room for baffle material be better?

    5. length? how long or short? is there a minimum length or a maximum length

    6. body material? steel, stainless, ally..... copper pipe maybe, im am an a-grade oxyacet braiser ; ) maybe on the flipside would some stiff plastic be ok?

    7. opened ended exposed foam/baffle or a cap? that question pretty much explains itself

    8. bullet path baffle cutting? drill/cut a bullet path in the hole, or fire a round through to cut one? does it matter if the foam/baffles are touching the pellet or not?

    a lot there again, as i said im looking for advice

    thanks for the help in advance
    jim
